Guyker 2Pcs Brass Concentric Stacked Knobs, Dual Knurled Control Knobs, High Grade Dome Volume Tone Knob Replacement for Electric Guitar or Precision Bass - CNC Machined (Black)

Fits perfect on my Sire v7 vintage

I bought these after installing a Bartolini preamp in a bass. The plastic Bart knobs were kind of lame... They fit well, and look and feel excellent. My only complaint is these stacked knobs and the same manufacturer's non-stacked versions are very different shades, even though they are sold as the same Smoke Gray color. They still look good together, so I won't knock off a star, just be forewarned if that might bother you.

Concentric dule purpose knobs!Don't be a dense do two things at once...

The overall quality is great. The sizing for some knobs may not match every bass. The bottom stack knob was size a little different so I mixed-matched it with a black bottom. It works fine.

Installed a BART preamp with stacked controls and needed to find concentric knobs. The have a premium feel to them and look great. I just wished they sold them individually as I only needed one. FYI they do match the regular knobs sold by the same company.

I have a Katana 100 guitar amp, it has two concentric control knobs one of which broke on me (tablet fell and struck it) I was hoping these would work, they are too big for that application. They are about the size of most aftermarket guitar volume/tone knobs. If you’re looking to fix your Katana, don’t get these.

My fault but these inner hole diameters are much too large for CTS stacked pots which appear to be typical for a Fender Jazz bass setup....

I bought this to match my other knobs also pictured, ( Guyker 3Pcs Guitar Potentiometer Knobs with 6mm (0.24") Dia. Shaft Pots ). Being that they are from the same manufacturer, it's a perfect match!I did notice while installing them, that they seemed a bit prone to scratches on the tops. But, I'm new to guitar making, so it is likely something to do with how I have my shop setup.
