I Built the circuit for Guitar Control (http://redcircuits.com/Page69.htm)

i Wanna use it for my Bass Guitar.

and it works fine... but there lots of clipping...(the breaking and cracking noise) mostly in the beginning... I checked all the connections and all the POT's but still the Clipping occurs....

and when i turn it off there's a buzz and then Becames silent...

other wise the sound is awesome... it rocks...

Can you tell me how to stop the clippings... is there's any solutions for the same...

FWIW:

My guess is 90% of those who read this can't read let alone understand that schematic (including me). You might be lucky and get some feedback from those on the board that make aftermarket pre's.

Speculating that won't happen I'll throw out a common sense take. Cracking and popping I'd speculate is poor connections. The clipping is a result of the usual, too much output of the pre.

Try ampegamps.com. Pretty tech oriented site and you probably would get some feedback of use there. In spite of appearance, the site has no affiliation with the Ampeg bass company I'm aware of.
