when to braid wires and when not to?

All frequent questions on switching: true or not true bypass, transistor-based or mechanical.

when to braid wires and when not to?

Postby zilla » 28 Jan 2015, 00:12

In an effort to try and clean up the wiring in my builds i'd like to try and start to braid the wires going to the pots.

i'm guessing/assuming that tone controls shouldn't add noise, but gain and volumes controls make me nervous, especially with high gain pedals like the dr. boogie.

can i safely braid the wires going to the gain and volume pots without adding noise or oscillation?

Wires in proximity form a tiny parasitic capacitor. Depending on what signals flow through those wires, it might actually reduce noise or HF oscillation (e.g. in a negative feedback loop) or horribly aggravate it (e.g. coupling input and in phase output).

Twisting the wires introduces inductance as well, providing higher resistance for higher frequency AC signals. That could probably eliminate some HF-noise, if used carefully.
