I just got a Spider III 150 amp and it came with the FBV Express and they worked together when I got it.
The presets from the last owner were not my thing, so I did the factory reset (hold A and turn it on). But now, the floorboard won't work.
It gets power and the LED next to VOL lights up, but it doesn't change channels, wah, tuner, or anything.
I unplugged it and plugged it back in with the A button pressed on the pedal itself and it ran the TEST mode, everything seems to be okay there. But it still doesn't work to change amp settings.
Of course, being an older model, I can't find anything helpful on the topic, so I joined here to figure this out.
Any help is MUCH appreciated in advance.
