I built a mini DI-box into an electric guitar to change unbalanced into balanced and to reduce the impedance significantly. Works like a charm, very fine sound and I'm able to go directly into a mic.preamp. Just advantages so far. But now I miss the possibility to alter the volume on the guitar, hence my question: how to put a vol.pot meter into a bal.-low impedance line. Thanks again, Arie

Phil In order to keep the lead from the pick up as short as possible and to avoid putting in another component in the chain that might affect the quality of the signal, I removed all the controls in the guitar. Hope that helps, Arie |
