OTT gain

[tcpoint]

I had a brief spell of madness over the winter.  This is what resulted.  Basically, it is an amb a20 line amp modified for a gain control.  I whipped together a bipolar power supply.  It has more gain than you can use but it's a lot of fun and sounds great.  If anybody wants to try this out, I'll pif a board and most of the parts plus I'll get around to writing up instructions - you'll have to supply an enclosure and power supply.  If there's more than one person that shows interest, I'll figure out a fair way to pif it.  Here's the amb project http://www.amb.org/audio/alpha20/.  btw, OTT stands for over the top - there really is no reason to have 0.1 ohm output impedance for a pedal.  I guess I could alway beef up the power supply and drive a speaker.

Mad but cool.  I did the enclosure and knob too
