ampy2000 0 Posted September 2, 2013 Hello all, I have an older FBV Foot Control. I use it on a spider 3 120 and everything works as it should. I also have a Spider 4 120 combo and the FBV will toggle from bank to bank but it will not let me save or edit on the Spider 4. any suggestions? Share this post Link to post Share on other sites
fflbrgst 1,832 Posted September 3, 2013 The FBV (even the MkII) is not used for saving/editing on the Spider IV amps. You have to do that with the front control panel (or Spider Edit if you have a MkII and have it hooked up through USB to a computer). Share this post Link to post Share on other sites
