Sign in to disble this ad
The volume knob of my Yamaha BB1200S is located very close to where inattentive strumming can cause an inadvertent volume drop. The rotational tension of the volume pot is pretty loose; an accidental impact from the picking hand to the volume knob can send it spinning, and suddenly the sound drops out. Aside from crude remedies like using tape or blu-tack to keep the knob from accidental volume changes, is there any other hardware that can help prevent this? A "weighted" pot? Some kind of spring-tab activated "knob brake" or lock that can be fitted unerneath the knob?
I don't really have an issue with it myself; when another one of my band members is using my bass on a particular song where I play regular guitar, his crude and inattentive technique causes this to happen almost every time, even when I warn him before the song to be careful not to accidentally hit the volume knob again. Some kind of small metal spring-loaded device that can be slipped under the knob would be ideal. Has anyone invented such a simple thing?

| | | | Take said bass away from crude inattentive player untill he improves. LMAO. Well, how about stuffing a peice of foam under the knob, betwwen it and body, just enough to hold it in place when clumsy is playing it. Lol.

If you don't change the volume at all, convert to a trim pot and use the hole for switch (active/passive, series/parallel, mid switch etc.)

Firms up rotation and does absolutely no damage to the finish. |

|  | LICENSED TO KILL - any song I play! | | | | | I have used felt washers. I take the self-adhesive felt "feet" sold in hardware stores for protecting furniture and such and punch a hole in the center. I then remove the knob, sandwiching the felt washer between the bass and the knob. I use the adhesive side against the knob. This creates resistance, keeping the knob from inadvertent movement. You might also try rubber O-rings, thus eliminating adhesive completely.
YMMV

| | | | dope slap FTW, followed by a rubber faucet washer from the hardware store. (you have to stuff a lot of felt under there to get any decent drag on the knob.)
oh, and who "strums" a bass?

oh, and who "strums" a bass? | Depends on the control hardware. If I loosen the volume set screw on a handful of basses, I can lower the knobs to a point where they come in contact with the face. Rubber washers do work well, also.

Riis | true enough, but since most metal knobs like that are sort of hollow at the bottom, the outer edge could indeed hit the finish while the inner part still had clearance. you'd have to either use felt big enough to stick out under the knob (ugly) or like i said stuff a lot under there.

| | | | not necessarily, some new pots are very loose.
besides, that's a lot more work than getting a $.50 washer from the hardware store.

also, I like the felt -- and if you need a lot of mass, just sandwich something thick, like a rubber gasket/washer, between two pieces of felt. Thick, stable, and won't mar your guitar.

I have one of these. Anyone who borrowed it and played it hard enough to knock the volume knob would not be invited to play it again.
