    I am trying to get a bit more high end out of the Fender Roscoe Beck.

    I like the "passiveness" of the bass but I am wondering if I could enhance the shy top end by:
    - changing the volume pot to 500 ohms.
    What are the pots on the RB anyway? 250 or 500 ohms?

    - using a push/pull pot/switch to take the tone and volume pots out of the circuit when needed. I don't want this to be a permanent thing.
    What pot would I need to do this? Who could describe me the wiring?

    You can get all sorts of documents on your RB at www.fender.com in the support section.

    Looking at the wiring diagram, you could take the signal before it reaches the volume control (after the pickup selector switch) and run it to the volume/tone bypass switch.

    A volume/tone bypass switch would need to have two functions...1) send the pickup's signal to the output jack rather than the volume control and 2) disconnect the volume control/tone control from the output jack. This is done with a DPDT switch (one section connects to the output of the pickup selector and either sends it to the volume control or the jack, the other section connects the jack to either the volume control or just to the pickups).

    The RB5 uses 250 Kohm (kilo ohm, not ohm) controls. Switching to 500K ohm controls might help.

    What mode are you using the pickups in? The parallel humbucking mode should be brighter than the series humbucking mode. The single coil mode would be somewhere in between.

    The RB5 has a pretty complex wiring scheme. If you're not very familiar with instrument wiring, you should probably have a tech do it. The initial cost is good insurance against future (and untimely (like mid-gig)) headaches.

    Good luck!!!

    1.) Brighter round-wound strings
    2.) 500 K pots might help.
    3.) Lower capacitance and shorter cable might also help.
