K20-X Preamp

I’m working on a veroboard (strip board) layout for a Dean Markley K20-X preamp.  It’s almost complete, but still untested.  Once I finish it I will need someone to do the testing since I don’t have time for that bit.  Then I will be making a version that can run off a single 9v battery (current one requires bi-polar supply of at least +/-6v).  I will build that one myself and then I can decide what other bits I can omit.  I’m thinking about not using the 3 band EQ at all since I will be using mine as an effects pedal anyway.
