This is the EWI Tourcase tm Model SVT road case, which is a pullover style case suitable for housing an Ampeg SVT bass guitar amplifier. Two versions are available the SVT-13 and SVT-14 with a 1" difference front to back between the two cases.
The side panels are constructed with 3/8 inch hardwood plywood and covered with a black ABS laminate surface. The extrusion is all aluminum and assembled with aluminum rivets. The rivets on the 4 recessed handles are backed with washers to ensure strength and durability and the inside of the case is fully lined with 1" closed cell foam rubber.
The SVT case is equipped with 4 recessed butterfly latches to secure the cover to the tray and four 4" swivel casters are included, two of which are locking style. The casters mount to a 3/4" plywood caster board.
EWI Tourcases are manufactured to exacting tolerances with excellent fit and finish. This is a well made case that is sized nicely to house one Ampeg SVT amp, however: Check the dimensions of your amp for proper fit before ordering since your amp dimensions might be different.
