When you want to attach your pedal to a board without destroying its re-sale value, the 125-B bottom plate is a work-around sub for the plates that Roland and Ibanez won't sell separately. A few caveats:

• The standard Boss screws are too short, so please use #4 x 3/8" self-tapping, SKU 8004N.
• You-ll need to file a little on the inner lip to get a proper fit.
• The standard Ibanez screws are long enough, but you will need to bore a couple of holes to make use of the existing screw holes. Also, you can't use the battery door.
