GT412SL/ST Guitar Enclosure

Your Crate GT412SL/ST 4x12 Guitar Cabinet is built
from the finest materials and components available. The
cabinet is carefully constructed and then covered with
extremely tough Tolex®. The cabinet is then loaded with
four Celestion Seventy 80 speakers.
The GT412SL/ST comes standard with casters, steel
handles, a heavy duty metal grille for ultimate speaker
protection, and a switchable, dual-impedance mono/stereo
jackplate. The GT412ST features a straight baffle while
the GT412SL features a slanted top baffle.
For those wishing to use multiple cabinets, the casters are
removable to accomodate stacking the cabinets.

IMPORTANT SAFETY INSTRUCTIONS:
1.Read, follow and keep these instructions. Heed all warnings.
2.This speaker is capable of producing high sound pressure levels that may cause
permanent hearing damage. User caution is advised and ear protection is recommended during use.

are equipped with caster cups on their top surfaces are to be used underneath a
cabinet which is equipped with casters.

away from any possible accidental contact.
