We sell these pots individually, the image shows two so that you can see more detail.

The best guitar pots we're aware of are made by CTS - this is the brand that pretty much every American guitar company has used since the 1940s.

This particular pot is designed for rear-rout applications, where the pot bushing needs to be long enough to pass through the guitar's top while still allowing enough threaded length to use the appropriate nuts and washers, (which are included). Most rear-routed guitars are designed with a 1/4" or 6mm top thickness, and the longer 1/2" threaded bushing on these pots makes them perfect for these rear-rout applications.

Be advised: These pots have 1/4" diameter shafts (6.35mm), and they are designed for knobs that are held on with a setscrew. Most imported guitars that have setscrew knobs come with metric pots with 6mm shafts - and accordingly, they come with knobs with 6mm holes - and these knobs will not fit on our pots unless the hole in the knob is enlarged to 1/4".

While this might seem like no big deal, in practice it's not something the average consumer will find trivial. A drill bit that grabs a metal knob and spins it in the hand risks cutting the hand, and especially if it has a setscrew sticking out on one side. Unless you have a drill press and a way to hold the knob from spinning without marring it, you might find it advisable to buy new knobs. All of the Fender and Callaham setscrew knobs we sell will work, they all have 1/4" bores and are designed for CTS pots with solid shafts.

5 star pots are first rate fit great shaft a little longer for rear routed guitars nice feel to the knobs up/down...cts pots good quality 👍

Too Much Torque

I ordered 10x 500k solid shaft with 1/4" bushing and 10x solid shaft with 1/2" bushing. The pots with 1/4" bushing are awesome straight out of the box. Very low torque, really fast.

Unfortunately, the pots with 1/2" bushing are considerably higher torque. I had to disassemble, remove the silicone grease, and adjust the tension of the wipers on all 10 of them. Worth the effort. Now they are smooth and low torque, exactly like the 1/4" types.

Great service

Needed to replace one of the pots in my guitar. Found the site and ordered the pot, it came on time and works great thanks so much for having what I needed.

10/10 would recommend

Just used a pair of these to build a harness for my Fender cabronita bass. Can’t beat the look and feel of genuine CTS pots.
