Video here: http://vids.myspace.com/index.cfm?fuseaction=vids.individual&videoid=&release=104156649 This is a DOD 250 Preamp/Overdrive that I had modded with a tone stack added and controlled via a tone pot (white knob). The input/output caps, diodes, and op amp chip are all socketed so you can swap parts in and out to your liking. I am including, free of charge, two extra op amp chips, two capacitors (larger value for more bass signal passing), a silicon diode, and a germanium diode. I have a non-stock op amp, red LED, and original input/output caps installed, as I thought this setup sounded best. This will ship installed in the pedal. The tone pot is ESSENTIAL for this pedal, as you can dial in more bass/roll off nasty treble. This pedal can replicate BJFE Blue Berry Bass OD tones with ease. $125 shipped USPS Priority Mail w/ insurance. My loss is your gain (no pun intended).
