Great Overdrive! Pigtronix Fat Drive - $90 shipped OBO
Just got this in. Plugged it in, dialed in some tone, and knew it wasn't for me. GREAT sounding pedal, great for getting a nice thick tubey drive but overkill when joined with my Meatsmoke Tube Preamp.
If you've got a B3K and are looking for more warmth, I'll throw cash in on my side.
It occured to me that there's not a lot of samples of how it sounds on bass out there, so here's a tiny sample. Straight through, no blending.
