cstevens5918 0 Posted December 7, 2013 I have a Spider 112 amp (red face) that is over 10 years old and I am looking for compatible FX pedals. I recently purchased the FBV Express MkII and it did not work with the amp. Is there any way to make the two work together? Share this post Link to post Share on other sites
TheRealZap 7,337 Posted December 7, 2013 you need the old floorboard or the FB4 (NOT the FBV4) for that amp. its in the manual here: http://l6c.scdn.line6.net/data/6/0a060b316ac34f0593561ea81/application/pdf/Spider%20User%20Manual.pdf you'll likely have to find this on ebay.
