BV412RVB/SVB Guitar Enclosure  
Your Crate BV412RVB/SVB 4x12 Guitar Cabinet is built from  
the finest materials and components available. The cabinet is  
carefully constructed from 13 ply Baltic Birch and covered with  
extremely tough Tolex®. The cabinet is then loaded with four  
Celestion Vintage 30 speakers.  
The BV412RVB/SVB comes standard with casters, steel han-  
dles, a heavy duty metal grille for ultimate speaker protection,  
and a switchable, dual-impedance mono/stereo jackplate. The  
BV412RVB features a straight baffle while the BV412SVB fea-  
tures a slanted top baffle.  
The BV412RVB/SVB also comes with a 14 gauge speaker  
cable to help insure maximum power and full frequency response  
from your new cabinet.  
For those wishing to use multiple cabinets, the BV412RVB has  
caster cups on its top surface to accomodate the casters of a  
second cabinet, stacked on top.
