FREQUENTLY ASKED QUESTIONS

What is the difference between A/C and M/N Blend pots?

Both blenders are passive. The A/C blend type has the advantage of having very smooth blend, but the disadvantage of lowering the output a bit. The M/N blend type has the advantage of higher output, but the disadvantage of the blend sounding a bit jumpy around the center detente.

What is a simple way to remove the correct amount of shaft from a stacked pot so that the concentric knobs will fit?

Slide a 1/4” brass conversion sleeve over the top of the shaft. The top that is exposed is 3mm. Grind the shaft down to that point and the concentric knob should fit perfectly.

Exactly what I needed!

I just needed a simple item - pots for an active preamp.
But finding the right combination of attributes (value, center detent, mounting depth) was seemingly impossible.

FBT had exactly what I needed, at a great price, and shipped them FAST!
