I know it's an amp, dingus
but now I want someone to make
Harder amps.
and
Rockier guitars/basses
I can't help you with that. but will the fact that Sundown (no relation to Sunn amps) made Rocky amps back in the late 80s ease your pain?
Regarding the OP question - I've had my fair share of good and bad stuff. At the present time (and I'm feeling pretty good about these), I'd have to say:
Guitar - my 2013 Gretsch Country I love my 1954 Country Club, and my Fender Toronado, and my Fender Esquire will (assuming I don't need to sell things due to a money crunch) always have a place in my aresnal. Ditto for the Schecter Jazz 7-string, and the Alvarez acoustic, but my 2013 FilterTron loaded Country Club has turned out to be amazingly flexible sound-wise, for everything from jazz, classic rock, to even heavier rock (with the right EQing, and taking care to keep the feedback under control). It also has a killer neck that plays sooo good! I've already pretty much made up my mind, that my 2013 Country Club is going to be THE guitar I'm going to play in the band, at the picnic gig the company I work for, is going to have in late spring or early summer.
Amp - Laney Cub 12R. It's tube, it has a 12" Celestion speaker, is 15 watts of power. It also doesn't weigh a ton, which makes it less of a hassle to lug around than the 50-100 watt 2x12 loaded amps I used to gig with years ago. Sure, its reverb is digital, but its fine for what I do (I'm not a surf guitar nut). The Cub 12R also has both a master volume, and an attenuated channel (that knocks output power down to about 3/4 of a watt), and takes pedals (including dirt pedals - the amp also has an effects loop) very well. It's not as high gain as some of the amps I've had in the past (with the gain cranked, you get 70s era hard rock sounds), and I've debated with myself about getting a Mesa Mini Rectifier, or an Orange Dark Terror, but, I end up realizing that with my dirt pedal (a Boss St-2 Power Stack [I never thought I'd see the day, where I'd use a Boss dirt pedal - I always thought they sounded awful]), I can get the same grind tones those two amps get. Oh yeah, and I paid all of $225 (used), for my Cub 12R. It's great for home use, and plenty loud for smaller gigs.
