Hi everyone,

 

Classic 2 Band preamp  (MM SR type) kit. = Volume, Bass and Treble.

 

 

I bought a couple of these kits, but realistically I don’t need the others any time soon.

I built and fitted one in a Cort bass with MM humbucker and it was a vast improvement

 

Ideal for upgrading a poor preamp or even making a two band eq pedal uses 9V dc supply from PP3 battery.

 

Good quality PCB and components , takes about an hour to solder up, all parts are included except wires for pots and a 1/4" stereo jack socket.

 

Alpha pots are 1/4” type so need appropriate knobs to fit (6.35 mm and  NOT 6mm).. I had to buy new knobs.

 

Uses the classic LM4250CN op amp, and comes with a socket.

PCB designed to be installed/mounted off the Bass pot, which has lugs to mount on PCB.

You could also mount this is another ways such bass cavity somewhere, and cutting off the lugs on the Bass pot and soldering to it in the normal way. 

 

**This is a kit, so need to be fully soldered and assembled**

 

£25 delivered

 

Thanks Neil
