Dig it! Master Guitar FAQ #4 - Other Guitar Electronics.

Don't forget pots come in two types - Audio Taper and Linear Taper. Audio increases and decreases exponentially so it is more acceptable to our ears as it is a gradual change. Use disc caps for the tone control and not electrolytics or tantalums. The later are polarized and are designed have some type of polarized DC potential on them which is great for Power Supplies.

You can also use shielding in the cavity whether it be lead based paint or copper strips to help reduce unwanted noise. I like using a .01uF cap between ground and the bridge wire. This way I don't get zapped from stray 60 Cycle or DC voltage as well as provides an efficient HF ground path.
 
tgk03! I hope my walking offstage attitude about equipment doesn't seem harsh for you,
especially if you're not used to putting it out onstage, and handling audience comments.
On the road, what looks so nice and graphically interesting becomes worn and dirty,
unless you like a ritual of cleaning your guitar, a nice thing to do, killing time in rooms,
or just waiting out a rainy day when you're in a city without your own transportation.
It would be a better world for me if I could boil strings to refresh them like bassists can.

Godin is really pushing their new guitar technology, plugging in to most synthesizers and working.
I don't see any new electronics as generating new sounds that are practical,
unless you are still using music as a weapon, through your own p.a. or a military application,
as the C.I.A. used against the Nicaraguan leader, Daniel Ortega, blasting super loud Metallica for days at his residence.

And as someone who was so caught up in the world of Marshall stacks and effects, after seeing Jimi,
I'm willing to say weird sounds that are moderately acceptable have been found already.
Knowing the world of classical music, all the different "voices", those frequencies generated by wood and metal and gut,
when rock musicians glom onto those, even through left-over home entertainment organs,
then musical complexity, and a new template of rock band might be possible.

What Modern Saint is typing about audio versus linear tapered pots works the same way acoustically onstage,
even if you're thinking about the historic human experience with different sounds and instruments, even symphonies,
what goes deep into our soulful consciousness, just like the rattle of the turtle drum shaker.

I'm sorry for my knee-jerk reaction. I appreciate your input and enjoy your posts. I've been a sofa noodler for so long and I want to bring it up a notch faster than middle aged coordination and reasoning allows.
 
oh look, John Watt has a completely reactionary and ethnocentric point of view. shocking. :rolleyes:
you mean you understood that? :confused:

back to the topic at hand, I'd like to throw this in there.

I will never again buy an instrument with active pick-ups/electronics.
or, perhaps I should say it so:
if I do, they'll be replaced with a passive system.
my "stage" bass has 'em, and they're fine for MUNG gigs, but at home, I have no need, or use, for them whatsoever
 
I'm about ready to strip the thread of posts that are not on-topic, since this is really supposed to be a USEFUL reference for the forum.
 
I really like the Gibson style varitone circuit. It is a cheap way to add a lot of different sounds to a guitar. I'm surprised more guitars don't have them, actually. I guess there never was a huge desire to have them, so guitar companies never bothered installing them, but they are a really neat device. They basically are a 6 position rotary switch wired in or out of the circuit on a push pull pot or toggle switch. When in the circuit, the varitone is a series of capacitors that provide various frequency cuts to the output signal, one capacitor value per switch position. This can really sculpt the sound of a guitar in pretty dramatic ways. The positions of the standard Gibson model are shown below, at least these are the values on my blueshawk.

Position 1 : Bypass (no effect)
Position 2 : -5dB at f0=1875 Hz
Position 3 : -6dB at f0=1090 Hz
Position 4 : -7dB at f0=650 Hz
Position 5 : -10dB at f0=350 Hz
Position 6 : -14dB at f0=130 Hz

Next time I rewire a guitar, I am going to add another one of these to the circuit. A couple of builders, aside from Gibson, make these things pre-wired and ready to drop in. I think they run in the range of 45-50 bucks.

The only thing I have found that is more versatile is actually having active pickups with an active pre-amp. With an active pre-amp unit (active meaning it can boost AND cut frequencies, unlike the varitone or capacitor that can only cut signal) I can turn up the treble or bass, turning my EMG equipped guitar from a metal guitar into something that sounds like a tele or a fat jazz box. Combine this with something like a dual mode EMG like the EMG89 (both an 85 humbucker and a SA single coil in the same housing), and put a hollow steinberger body under it and a giant metal trans-trem behind it, and the tele and jazz box claims don't seem so crazy.

i have a pedal called the Catalinbread Varioboost. the original was a Varitone with depth and volume knobs so that you could keep the level consistent. it's a cool circuit. (later versions were changed to a parametric EQ.)

as for the original premise of the thread, i tend to be a bit more specialized in my approach. for instance, the volume and tone pots on my PRS and Ibanez are push/pull. each pot puts a pickup into parallel operation for a thinner, but still humbucking tone. combined with a 3 way switch, i like the combinations, the thinner sounds, and the silent operation. i go with audio taper pots, but tend to leave the treble bleed mod off. i just don't think it's really necessary in my setup. but i do like the premise of treble bleed caps.

regarding different value pots, it does make a difference. nobody is ever going to want to use a 500k pot on a tele bridge pickup. the treble will shear your eardrums apart. but depending on the humbucker, i would even consider a 1meg pot.

i don't go for cloth wrapped wiring or silver solder, or any of that corksniffer stuff. a clean solder joint is a clean solder joint and none of the expensive metals are going to have a different tone than regular old tin solder. electrons only know that they can pass, not how much you overpaid for something.

I agree on the series/parallel wiring idea on humbuckers. I really like this and have added it to a couple of my guitars and set it up to a mini toggle. I also agree on the 'non cork sniffer' choices of materials. I use whatever wire and solder I can find kicking around in my toolbox. Doesn't seem to make a darn bit of difference.

I pretty much roll with electronics as is in a guitar. Pots need to have a nice smooth taper and no abrupt turn on point. Pickups need to be articulate and percussive which pretty much means I prefer low power pickups. For replacement parts I use CTS pots and switchcraft jacks.
 
Electrons and their activities should not be taken for granted by any electrician, or serious artist.
Electrons are the building block of life on our planet, what makes our brains work, if nothing else.
No-one on earth understands this life-giving, and earth-transcending aspect of our existence.
No-one knows where this energy is created, or where it goes when we die. But we do exist.

Your electric guitar is a live circuit. Mixing variables of electronic values creates a complex magnetic field.
You defragment your computer, why not look at your guitar that way. It is more complicated,
feeding off human input, and human musical input at that, far beyond mans' ability to build a similar "machine".
For me, it's all about the potential, the different sounds, environmental absorptions, of your synapses and guitar pickups,
so you can reach out and blend with everyone's musical heart, and take it from there. That's not an act.
That's being a musician.

please show, with quantifiable data, that a signal passes through standard tin solder more poorly than other forms, and that it can tell what wattage iron the solderer is using.

until then, you're just dancing about architecture.
 
No... no... Flamencology, even if you're right, but no... Help!I'maRock! is right, coming in from the storm.
Architecture is a good build term, and eventually, why I like it onstage, I do get dancing, around it, and all over it.
I did get gigs where I was told nothing before the mike, no whipping with guitar cords, no hitting the cymbals, etc.
But that's my problem here, the dancing of it all.

Different solders, wires, lengths, all create or interfere with optimum magnetic patterns.
So, Help!I'maRock!, I'm not trying to be trippy, dancing over it, thinking in terms of holding a drill in front of a pickup,
to make motorcycle and chainsaw effects, or avoiding vacuuming when your guitar is close, to maintain field strength.
That's how delicate our types of magnetic fields can be.
Look at Tesla, for a historic electronic example, relevant to our commercial supply, what our guitars use.
We're using Teslas' variation, what we now call AC-DC, as a current characteristic, but not his distribution method.
Dr. James Watt used wires to proliferate his electrical generation, and as we all know, we're talking watts now.
If Tesla was followed, we'd be living in an electronic atmosphere, scientifically possible, but...
would you want to live in a world where hydro capacity fills the atmosphere, and individual homes and outdoor appliances
just need to stick an antenna up to catch some juice. That would be medically wrong for our brains, not known back then,
except for maybe to Dr. James Watt, who travelled the world to mitigate the potential damages of the electronic revolution.
That's historic, scientific, but... is it still something that helps you understand electric guitars. It should.
Uh-oh... office hours over.... gotta go!
 
Along with my literate approach, enjoying myself, I supplied irrefutable, quantitative data.
You might not have seen it that way, because I'm expecting you to try for yourself.
I'm hoping you'll find an active electronic, magnetic field, by trying a drill or vacuum cleaner, as described.
You'll never see it, unless you can form a nucleac cloud of magnetic material that will coalesce in the air, revealing a magnetic pattern.
I've never had that opportunity, just spending a lot of time in front of a 100 watt Marshall stack, mostly by myself.
And as easy to hear as the drill and vacuum are, you are degrading your electronics by doing that.

I'd think of the electricity leaving your pickups as water down a drain.
If it's flowing all together, not a combination of soapy, greasy, or hair product water, like having too many electronic values,
then it's obvious the water will flow most efficiently, providing a focus that can be aimed efficiently.
Think of the water circling your drain, now with your finger in it, creating a sub-vortex that is part of the main flow.
Who cares about that, or how different art works, icing for cakes, to animated screen savers, can look good,
because different materials repel each other and make their own patterns.
Electricity is more atmospheric than that. Shuffling your feet on a rug while you're playing to create static electricity,
is as much of a variable source of electricity as different 9-volt batteries.

Musicians say if you can't sing it you can't play it.
Scientists say if you can't describe it, you can't build it.
John Watt, inventor, says people don't care for something they've never seen or heard of before, or tried.

Peeker! If you want to come over, I'll let you look.
If you promise to behave, and not leave lipstick stains, I'll let you sit with my guitar upside-down to try it.
Only maybe by the time you're done it won't feel, uh, upside-down.

Mr. Mark Wein! Yes, I would question the usefulness of my semi-solid-body references.
All along, the guitarists I consulted and talked to said it would be a low percentile invention,
something only 5 to 12% of electric guitarists could understand, hear or feel the difference.
I kept boosting everything in balance as best I could, having a real good time,
getting a lot more than I thought, and invented "accelerated acoustics".
That's so pickup focussed, nothing else matters to me anymore,
getting acoustics through the pickups trumps any new sound effect,
because it makes the whole guitar more playable, plugged in or not.
The unexpected, greater neck feel is the best bonus.

I typed inventor. But at my age and experience, having something new and exciting is a real miracle.
Those acoustics were out there already, waiting, and I certainly didn't create that world, and universe.

you provided nothing, John. you made an assertion and have nothing to back it up. the truth is that nobody can tell the difference between solder types. unless you can prove it, and you can't, you're just talking out of your ass. again. and it's that kind of blind corksniffery that fleeces people of hundreds of dollars buying stuff they don't need.
 
I'm not talking about the differences in solder, even though there are. I'm talking about too much soldering, unbalanced soldering design, and the "luxurious" electronics that get soldered into guitars. My bottom line about solder? Take your guitar, cord, effects and amp, and what sounds just as good, gold wires to your speakers soldered with NASA technology, or just twisting the wires together? You're right again! Unless you are just trying to extend a speaker as far as possible, over a hundred feet away, and just measure for volume, you and I won't hear a difference.

tgk03! I'd like to comment on your line about being a middle-aged couch noodler,
thinking that and your middle-aged brain are going to hold you back. I think you're totally wrong.
In the symphonic world, most violinists aren't considered virtuosos until they're sixty or sixty-five years old.
Let me apply that to you.
But first, from a real world, real life, perspective, you're there already.
You have a residence, definitely a couch, and have equipment and are playing already,
and are hot and heavy enough about it to be posting here, and coming across, at least to me.
So you can afford to just be as professional as you want, when it comes to performing.
You don't have a band to be responsible for, and you're not known as a single, acoustic artisit.
So not only can you be anything, but you are financially grounded, and can afford be and do what you want.

And you're not beaten up, physically, by having been a road or full-time player all these years.
Even if your mature self loses it, and you come out of rehab, it's new news that might pump up a career.
You're an unknown quantity, and will be a fresh and new act, in a band or solo.
You haven't been part of a recording act, so you can enter competitions because you don't have a contract.
And with a couch, you might have a garage or basement you can use for band rehearsal,
making you an attractive potential bandmember, even for young and hot to trot players.

What you might be unaware of is the extent you have to exercise and loosen your fingers,
to keep them going past middle age, into the virtuoso vector.
Don't be so self-conscious, definitely don't be shy, unless it's Peeker, just let him see a little.

I recommend getting into the song "This Masquerade".
You can be rootsy with it, gettin' Nawlins wit'it lak Leon Russel, who wrote and first sang it,
or you can elevate yourself with Mr. George Bensons' version, who set a new standard for jazz-funk-pop production,
playing guitar like the genius he is.
