I've got a DMM modded by Howard Davis that I may put up for sale. It's got the TL072 and input headroom mods that cost about $100 (with shipping, etc.). It's dead mint with paperwork, box, etc. I really can't research the price of this pedal, as there are not lots of Howard Davis' modded DMM's on the market. I paid $225 for the pedal and with the mods I've got $325 invested. What's a fair price? BTW: I reserve the right not to sell this! I am just considering!!
