I just got an email from Analogman on my KOT order. In this email, he states that it will be a long wait and he suggests using a Maxon OD-silver. Not sure what a silver is but I have a OD-9 and I would put that pedal up against any other pedal out there. The Maxon is a permanent staple on my pedal board and I rarely ever not use it. I get tired of my other OD pedals and will switch them out occasionally but that Maxon stays put. It sounds so good and it just cant be match in tone that I have discovered! Any other OD-9 owners out there that are as happy as I am with mine??
