| Gustav | Re: building onboard active preamps 10 meg will let the piezo sound good. If you have access to a scope connect the scope probe to the pickup(pickup disconnected from the circuit) pluck a string and look at the voltage output, the clamp will help keep the fet safe( the clamp clamps the voltage at about +.7v above Vcc and -.7v below ground) |
