Göldo JB-Style Knob Small

Göldo knobs are super close to the original JB knobs. The aesthetics are almost identical and I think even the JB nerds wouldn't notice the difference. I have this one (the smaller version which is for tone control) on my original JB, and it blends perfectly with other two bigger volume knobs.
So if you're missing tone knob on your JB style bass, just go for this one, you won't regret it. Of course, since this design is pretty awesome, you can use it for any other potentiometers with standard shaft dimensions.

I actually bought these for one of my Orange Micro Series heads rather than for a bass, but they look great, fit perfectly and the quality is top-notch.

Absolutely no complaints!

This potiknopf is excellent for my bass guitar savrsenos e fits with the color of my bass. Easy to install and it does not slide. I recommend everyone to purchase who makes his guitar, or when changing an electronics on his old guitar.

These knobs look great and feel good. I bought 3 of them to replace the knobs of an Electro-Harmonix pedal (which I find really boring and almost ugly compared to other knobs). Looks much better now.
