The Asymmetric has completely transformed this pedal at volume. I had a meeting in our Midtown office this afternoon and was able to drop off my Tele for a once-over to Matt at 30th Street Guitars, which he completed right before band practice with my cover band. I was able to play both the Tele and my Rev bass through the pedal and it's just plain awesome.
There's still a bass cut, so it can't be the only pedal on bass. But it no longer flubs out and has an incredible high gain sound.
On the tele, it's just perfect. I love the Tele with the Llama. But because this is a traditional overdrive/distortion pedal that's really based on the MXR Distortion +/DOD 250 (there's a couple of minor changes in the circuits, but they're all very close); it's voiced very differently. You do get that bass cut. It does goose the amp. It can be used as a dirty boost or a full out fuzz. The Llama has a more full range sound and sounds great with humbuckers. But the RAT, especially with the mods, just has something with single coils the Llama doesn't. I'll try to pin it down over the next couple of weeks. But tonight, I'm very happy.
