So in general, there isn't really a necesity of an intensity pot for the sustainer?

So I put the pot for changing the intensity of the Sustainer into the amplification circuit? Is the preamp in the Fetzer/Ruby the JFET and the LM386 the main amp?

Hey I got an idea: would it be possible to put an extra volume knob between pickup and preamp, additionally to the one between pickup and output jack? This way I wouldnt need a switch, I can just turn the sustainer off by turning the pot to zero, and change it's intensity by using the pot?

And just to make sure: I would use a 5k or 10k linear pot for that?

Hey thanks a lot for your help. Now I only need to know which values should be changed for a bass in comparison to a guitar.

I'm not sure, but doesn't the driver need to be "stronger" to drive the bass strings? How can I make it "stronger"? Higher voltage from preamp? Or maybe a stronger magnet?

Anyways, will a regular humbucker magnet be fine for the driver, if I use it as the core of the coil?

And where in the circuit would I put a potentiometer to be able to change the sustain? Between preamp and driver? And which impedance should it have?

Between preamp and driver is also the right place to put a DPDT switch for an out of phase mode, right?

Thanks for that link, helped me a lot.

Two more questions came up recently: Will the sustainer only work if the bridge PU is a humbucker? On the Fernandes Website they say their system only works with humbuckers.

And isn't it preferable to conncet the sustainer before the Volume? Otherwise, if I turn down the Volume knob I can't use the sustainer properly.

Will it be something like this?

Bridge PU -> Volume -> Tone -> Output Jack

Hello, can someone please be so kind and help me with a shopping list for the Fetzer/Ruby Amp, and and wiring diagram for a bass with 1 Pickup, Volume, Tone, and a Sustainer?

Has anyone tried the sustainer on a bass yet? And isn't it possible to buy a small preamp like this, or will I have to build one?

I can wire a guitar, but apart from that I know pretty much nothing about electronics...
