Big Muff Pi EC3003-A, this particular one an early "Frantone" era model. This one really runs the gamut of tone everywhere from wooly with the tone counter clockwise to really raspy and cutting as you get higher on the tone knob. One of the best sounding Big Muffs I've ever played.

No functional issues with this one. Has the battery door. Sounds fantastic. Lots of mojo. Case is sturdy. Tested and works with either power supply or battery - no issues.

Cosmetically, please evaluate the photos for yourself - plenty of scratches in the paint. The cosmetics are the only reason it is not listed in a condition higher than Good. It's seen some playing in it's day for sure. Bottom does not have any of the rubber feet. There are two new parts: 1) the replacement knobs and 2) the battery clip terminal. When I got this, the knobs had been replaced with generic knobs - not the right look. So, I went out and found Davies style knobs to replace them. Now it looks as it should. I replaced the battery terminal as the other was shot (I will include the original terminal as shown in photo for posterity sake). Everything else is stock. I tried to photograph this pedal well to show the cosmetic condition, but please let me know if you have questions - happy to talk gear.

Please check out my other listings. Fast shipper!
