I'm thinking of having a few FET PCBs made and wanted to get opinions on the best way to implement a relay to switch it in and out of the circuit using a single input jack.  The relay would be located on the FET PCB.
The easiest way I can think of is to use the same DPDT relays as used on the PAB and OD/Clean selection and configure it as a true bypass switch like an effect pedal.  Has anyone tired this or can think of a reason it won't work?  Thanks.

Re: FET PCB with Relay
Should work,  TR does this on a few of their models.  I have thought about something similar (but won't use a FET,  there are much better options out these days).
I would take care to make sure that the FET input is grounded when bypassed as it could create a lot of noise on the V1 supply line.

Re: FET PCB with Relay
Thanks. My favorite clean boost with dumble style amps is the Xotic RC pedal. It's especially useful when running the amp at lower volumes. I never alter the bass or treble (always set flat) and rarely alter the gain or volume. I may look at what's in the circuit and build something similar with a variable output in place of the standard FET.glasman wrote:Should work, TR does this on a few of their models.
