Used DarkGlass Electronics MICROTUBES B7K ULTRA V2 Bass Pre-Amp Pedal

The Darkglass Electronics B7K Ultra V2 Bass Preamp Pedal is a studio-grade bass preamp and overdrive pedal built for players who demand precise control and aggressive tonal shaping. This unit features Darkglass’s signature Microtubes distortion circuit alongside a full 4-band EQ with selectable mid frequencies, plus controls for drive, blend, level, and master. It’s in excellent condition with light cosmetic wear consistent with normal use, and all functions operate as intended.

The B7K Ultra V2 is a go-to for modern bass tones, delivering everything from clean, articulate low end to tight, grinding overdrive that sits perfectly in a mix. The blend control keeps your low-end intact while dialing in grit, and the onboard cab simulation with XLR direct out makes it ideal for live gigs, recording, or direct-to-FOH setups. Whether you’re playing metal, rock, or anything that needs clarity and punch, this pedal gives you pro-level tone shaping in a compact format.
