I have a 9volt only NTMB pre 3 knob 1 switch. Vol,blend,tre/bass stack with a mid boost/cut switch. The switch can be moved out and a mid pot can be wired in. 65.00 shipped in the us only Thank you
no camera pics but this the best way to explain it. the pre came from an MTD grendel it has 3 boxes and can only be wired for 9 volts. it's very similar to the pre pictured here if not the same.
