The MU-FFSYN is an extremely durable and versatile synthesizer cart. At 58" wide, it's able to accomodate just about any sized synth; All the way up to 88 keys. Smaller keyboards leave plenty of room on the top shelf for additional hardware samplers, like the Yamaha DTX or Roland SP-404 MkII. To top it off, the top shelf is height adjustable from 29" to 37" for player comfort. 
 
The bottom shelf is great for storage of pedals, cables and any other extras that may need to be on hand. 1.5" square steel tubing lines the front and sides for clamping anything that can be mounted with standard percussion clamps.
