Each case is designed specifically to fit each model of instrument. Heads and cabinets can seem to be very similar in size, BUT they're NOT exactly the same. Even 412 cabs are slightly different from each other. It's extremely important that each case is fitted properly, in order to allow the 1" foam lining to protect and allow maximum FLOATING ACTION in order to provide correct SHOCK PROTECTION for your delicate equipment.
If the case is TOO LOOSE, your instrument is shaking around inside; if it's TOO TIGHT you'll be struggling to remove or put on the lid each time you unpack. With 33 years of experience, the design team at affordable-cases is qualified to designate the CORRECT size fit for each case to properly fit your gear.
