The Crate VC3112 preamp section is the multi-stage tube preamplifier paired with the VC3112's EL34 power amp, providing clean and gain channels shaped by 12AX7 triodes. The dual-channel design allowed players to switch between sparkling cleans and a harmonically rich overdrive voiced after classic British and American reference tones. Together with the power amplifier, the VC3112 represented one of Crate's most fully realized all-tube designs.
