DESCRIPTION

These concentric aluminum bass knobs are a clean, low-profile option for stacked controls and are now available in your choice of Black or Silver. Each set features a prominent line indicator and the solid feel of machined aluminum.

The lower knob fits an 8mm potentiometer shaft and the upper knob fits a 6mm potentiometer shaft. They're an excellent finishing touch for compatible stacked volume, blend or EQ controls where you want a clean, coordinated hardware setup.

BUILD A MATCHING KNOB SET

Have both stacked and single controls on your bass? Pair these concentric knobs with our matching single aluminum knobs to create a coordinated set across your entire control layout.

Choose the matching finish for a uniform look, or mix Black and Silver knobs to create your own combination.

The single knobs are designed for 6mm solid or 1/4" split-shaft potentiometers and include a brass sleeve to accommodate the different shaft sizes.


FIT & COMPATIBILITY

Upper Knob Shaft: 6mm 

Lower Knob Shaft: 8mm

Available Colors: Black or Silver

Construction: Aluminum

Indicator: Line indicator

IMPORTANT: Measure your potentiometer shafts before ordering. These concentric knobs require a 6mm upper shaft and an 8mm lower shaft.

Sadowsky Preamp Compatibility: These concentric knobs do not fit the Sadowsky preamp and are not suitable replacements for imported basses and preamps without first verifying shaft dimensions and fit.

FREQUENTLY ASKED QUESTIONS

How can I get these stacked aluminum knobs to fit a compatible preamp where the potentiometer shaft is too long?

Some compatible preamps use the correct 6mm/8mm shaft diameters but have a top shaft that is approximately 3mm too long for this low-profile knob. In those applications, the shaft may need to be shortened by 3mm for proper fit. Always confirm the pot dimensions and installation requirements before modifying a potentiometer.

Can I get matching knobs for the non-stacked controls on my bass?

Yes. Our single aluminum bass knobs can be combined with these concentric knobs so stacked and individual controls can share the same style. You can match the finishes throughout the bass or mix Black and Silver.

Everything was as advertised

These guys are great to work with. I rebuild a bass and ordered most of my part from them. I mistakenly thought a part hadnt shipped so I contacted them. They answered right away and you can tell they were concerned. Turns out the part has already been delivered. That's customer service you just don't get anymore. Will definitely use them for any other projects I have.

Brilliant product great customer service

I ordered some bass control knobs and the arrived fast and well packed. There was a manufacturing that was purely cosmetic not Fat Bass Tones fault. They immediately replaced the faulty product which arrived swiftly. Very happy with the products and also the friendly service.

FBT - Bravo!

I live in the UK and have supreme confidence when ordering overseas from these guys. Their speedy communication and willingness to help customers is second to none. My bass is fitted with two of their products and I’m waiting to install another product on another bass guitar.

My only regret is not discovering Fat Bass Tone sooner!
