On my bass there is a magnetic and a piezo pick-up. A simple onboard preamp adapts impedance for them, and there is only one treble control, and it works only on the piezo. When both are blend 50/50 the sound is as i like it, except it needs more treble. Adding treble after the onboard preamp adds more hiss than i like.
Do any of you know an onboard thing with possibilities for my setup (piez/mag) - and with tone shaping possibilities - and with low noise? Please tell me...
