Re: Less electronic knobs
For strongest, brightest signal all the time, go without knobs altogether! I saw a guy once whose bass only had an on/off switch. I actually thought that was kinda cool.
Personally I like having a little more control. It is true that pots can sap some of your tone & volume, and for a while it wasn't unheard-of for some players to wire a "blower' switch that connected their bridge pickup directly to the output jack.
But these small effects can be a positive factor, too. Many have fine-tuned the tone of their instruments by choosing different volume pots, for instance- it affects the sound even when the controls are wide open.
