This Kit contains everything you need but the momentary switch:
- PCB
- programmed microcontroller
- Fujitsu FTR-B4C relay
- CPC1017NTR Optocoupler (SO-4)
- 78L05 voltage regulator
- BC549 or equivalent transistor
- 1N5817 diode
- 100nF MLCC cap
- 100uF p-electro cap
- 3 resistors
- 3mm clear LED (red,green,blue,orange – specify with your order or you get a random color)
Soft touch momentary switch can be ordered separately.
When kits are on backorder you still will receive it in 3-5 days time.

I used this to make the reverb on my Fender Princeton Chorus foot switchable without running the reverb signal through the foot-switch. The relay unit’s voltage is regulated down to 5VDC by a 78L05, so you can use a higher voltage than 9VDC. I ended up using the 16VDC rail in my amp. I used the relay to ground the reverb return signal at the PCB. The unit is small and it was easy to find a spot to mount it in my amp. It functioned flawlessly.

Used a pair of these for a loop switching/blend unit for my delay and reverb, and they work perfectly – no more switching noise.

Works great!
I modified this, to include a second FTR-B3CA-4.5Z relay, in parallel with the main relay, for switching of two status led’s (green=on/red=off). Added a heatsink to Q1 as part of this modification.
