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 ?

I think you'd be on your own trying this... don't know why it wouldn't work... but certainly don't think L6 can support doing this.

Well yeah. Of course it isn't going to be supported; I AM a realist! :)

The real actual FBV has to wait until I can scrape together another $200 for the shortboard (sigh). In the meantime, I just want to update it to its full potential.

It would be nice if L6 could at least give me a heads-up as to whether this is safe and isn't likely going to hose my stuff -- even if it's full of caveats and misgivings. It's not like ppl haven't been poking around inside their amps / pedals / etc to customize their guitar tone since... forever? It's unsupported activity, but experts can still provide friendly, helpful info to a conscientious & careful tinkerer, right?

...right?

Line6 personnel were no longer reviewing posts on these forums (old version), so may not see your question.  You could try opening a support ticket to see if they answer.

If you bought your amp from a brick-and-mortar store near you, you could bring your amp there and ask them if you could do the update through their demo FBV.  I've heard of others doing this.
