Hello! (and congrats on the new forums!)
I have a Spider IV 75 that I want to update to the latest firmware, etc. The MKII FBV Footswitches are a little pricey for me atm, and so I wondered if I could simply use the PCB from a FBV Express MkII to do the job?
I've found them on ebay selling for ~$10 for just the bare main circuit board; this is much more within my price range! None of the other FBV parts are included: no lcd display, no leds, no dummy input loads.
I recognize that I will be unable to use the pedal's other functions (like, for instance, the pedal-y or stomp-y parts), and that's fine. I just want to update my amp.
Since it appears a non-trivial amount of current flows to the FBV unit from the amp, I'm going to check first before I blow my $300 amp + $600 PC
Ultimately I want to know:
Assuming all cables are attached properly,
1) can the bare PCB from a FBV Express MkII can be plugged into the Spider IV amp & my PC without risking damage to the amp or my PC?
2) Will I be able to update the amp with this setup ?
