SWR

Overview

A direct descendant of our classic Bass 350, the 350x is the perfect solution for anyone who wants the classic SWR tube preamp sound in the most affordable amplifier package available. It's perfect for pairing up with a Goliath Junior III 2x10 or Son Of Bertha for small gigs, or with any single 4-ohm cabinet (Goliath III 4-ohm, Goliath Senior, Henry the 8x8, Triad) for a killer head-cabinet combination. And like all X Series amplifiers, it comes equipped with our exclusive Subwave effect onboard.

Features

Features: 350 watts @ 4 ohms, classic SWR tube preamp with Aural Enhancer, Subwave, studio-quality three-mode XLR out (direct, direct + Subwave, line) with ground lift and level pad, three-band active EQ with variable midrange, automatic limiter with defeat option, side-chain effects loop with blend control, fan defeat switch, tuner send, Speakon and 1/4" outputs. Footswitch for Subwave effect included.
