Any questions you might have about any pedals here I will try and answer them. This is my board trying out my old original SansAmp, a Barber Burn Unit and a Barber Tone Pump. Lately I have had a Honey Bee OD and a Zen Drive Gold in the slot. Some of the pedals I tested out. The mini pink one is a Shini Fuzz MHammer style. More OD. My tubescreamers and an old Boss OD. A couple of fuzzes I like. These are the switches on the SansAmp. It is actually pretty nice. I have had it for many many years. I don't remember the last time I used it. At least 10 years.
