This is not the FBV or FBV Mark II, it's an old FBX shortboard that I just found in a new house I moved into. Anyone know if it is compatible with any of the spider IV amps? I cannot seem to find any info on the FBX and am curious if I can even use it.
Try it. The worst that will happen is it won't work. In that case, you can always sell it.
It will only work with spider I series, Flextone I/II, AX2, some original POD 2.0 will use them also, but no L6 amps made in the last 10yrs will work with the old floor-board
