I have a lower end P-style bass. It's a Lyon by Washburn. I have had all kinds of Jack troubles, so I want to replace the jack. Since this is a backup bass, I want to experiment a little. I personally prefer the tone of the bass at full volume, so I was wandering if there is any way that I can wire the bass to bypass a volume knob, but include a passive treble and bass cut. I have never worked with wiring before, so good descriptions, perhaps even diagrams would be GREATLY appreciated. Thank you in advance!
