Mesa/Boogie Subway+ Bass DI-Preamp II
The MESA Subway+ Bass DI-Preamp II brings premium MESA bass tone into a compact, pedalboard-friendly format. Designed for active or passive basses, its extended-range J-FET preamp delivers the feel, response, and flexibility the Subway Series is known for.
Deep and Bright switches, a variable Hi-Pass filter, footswitchable Boost, and separate Gain and Master controls make it easy to dial in everything from warm clean tones to mild overdrive. A Variable Voicing control and active 4-band EQ offer even more precise tone shaping.
