Would This Work?

[wickerwolf]

Hey would something like this Variable caps be usable in a custom guitar circuit? (Eg, in a varitone etc so different tones can be dialed in)

[micpoc]

It probably would work. But it looks like it might be rather large, and would it offer any advantage over using the standard varitone / rotary switch implementation?

Hmmmm...don't think it will work. The range of the variable capcitance in those units is usually in the order of 10pF to 100pF or so. The capacitance is so small that it becomes unusable for guitar work - they're ideally suited for circuits that operate in the hundreds or thousands of KHz region (ie radio), not audio circuits.

Not to mention the fact that a tuning capacitor will start doing exactly that--tuning in radio signals and making the first circuit in your amp with spurious oscillation start tuning in KOMA out of Moore, OK.
