I have a Woolly Mammoth clone pedal. I have never played through an actual Woolly Mammoth, but this one sounds like the reviews online to me. It shakes the house when I play it.
I'd like to trade it for your Octave Pedal (Aguilar, mxr, EBS, OC-2, etc), or even your Preamp Pedal (Sadowsky, etc). I'll throw some cash toward the right pedal.
Or surprise me with a trade. I'm also looking for some 4 string Jazz pickups (Sadowsky, EMG, Bartolini, etc.).
