    My rear routed bass has a hole for a knob/pot that I'm nolonger using. Know any creative tricks to cover up the hole? I'd rather not use a dummy knob because the positon of the knob gets in my way.

    I've seen and used several options for this type of thing.

    The most expensive is to plug the hole with a dowel of the same type of wood, cut it off flush at the surface and blend the finish in to the original.

    I have seen other people glue coins, marbles, fake gems, and other items into blank pot holes.

    Put a switch in. There is always somethin interesting to do with a switch.

    Brilliant! A switch it is! One tone knob (or maybe master volume), and a switch to bypass it! My two holes are now filled. (Man I hate knobs. Pickups to jack and nothing in-between.)

    I'll 2nd the switch. I just had some work done on my Schecter Elite 4. I went passive (although now I've changed my mind and am going back to active/passive) anyway.. There were 4 knobs, and we were left with a vacant pot hole, so my luthier put in a coil splitter switch. I'm still keeping it, I'm just using a stacked bass/treble pot to take up one hole.

    Maybe a kill switch?

    I've done this many times on both wood bodies and plastic pickguards. Inside the cavity, cover the hole with a good stout masking tape or duct tape. Then mix a small amount of 5 minute epoxy with a bit of alcohol and lampblack powder in it to get it to flow right and make it black. Then, with the guitar laying flat, drop a few drops of the epoxy in the hole. Use a toothpick or small wire after every few drops to make sure there aren't any bubbles. Once it's filled flush, I put in an extra drop or two with a toothpick to give it a slight crown so it looks a little better. After it cures, take the tape off of the inside. True, it ain't as nice as making a plug and repairing the finish (which will always be seen as a patch job anyways), but most guys won't like the $200.00 bill that comes with that. For a decent fix on a workingman's bass, this will usually do fine.

    A year or so ago, I filled two unused holes in my fretless, but I had matching timber and it was right before a refin.

    I've done ThundePig's idea also, but I put the tape on the outside of the bass/pickguard. This way it doesn't need as much flatening etc. Experiment with pigments and materials etc and results can be pretty good.

    If your jack is in the side of your axe, I would think about relocating it to the front (a personal preference).

    But I think the switch is the best idea! Leave it disconnected and when a sound engineer complains about the bottom end, let him watch you switch it, and ask him if it helps... nine times out of ten he'll say "yep that's much better"...
