Good quality, fast shipping

Works great on my bass guitar. The knob fits snugly. Only giving 4 stars because the solder lugs were a bit stiff to bend.

Perfect replacement for my Strat

The 18mm shaft was exactly what I needed for my thick pickguard. Smooth rotation and no crackling sounds after installation.

Exactly as described

I bought this to upgrade the tone pot on my Les Paul copy. The long shaft cleared the body thickness perfectly.

Great value

Can't beat the price for a 500k long shaft pot. Installed two of them in my custom build without any issues.

Smooth action

Very smooth taper. Makes volume swells much easier to control. Highly recommend for DIY guitar projects.

Decent but knob is loose

The potentiometer itself works fine, but the included knob feels a little loose on the shaft. Might need some extra padding.
