Description

The Unleash V2 by Bad Cat

The Bad Cat Unleash V2 is a reactive load box, power attenuator, and re-amplifier designed to give guitar players full control over their tube amplifier’s volume and tone. It allows you to push small amps into higher power output or safely attenuate loud amps down to bedroom or studio levels without losing the natural tube amp response. The unit uses reactive load circuitry so the amp “feels” like it is still connected to a real speaker cabinet, preserving dynamics and tone. It also includes features for silent recording, an effects loop, and a built-in headphone/direct output with speaker simulation. Overall, it is built for players who want maximum flexibility between live performance, studio recording, and home practice.

Specs:

• Power handling: 1W – 100W tube amplifiers
• Reactive load design (cabinet-emulation behavior for natural amp feel)
• Switchable impedance: 4Ω / 8Ω / 16Ω compatibility
• Dual speaker outputs with impedance matching
• Two foot-switchable channels (for volume/level switching)
• Built-in effects loop (post power amp placement)
• Silent recording mode (disables speaker output)
• 1/4" line out + headphone output with speaker simulation
• Speaker phase switch for compatibility control
• Compact chassis design (approx. 5.5" x 5.5")
• Weight: approx. 4.5 lbs (about 2 kg)

REVIEWED: BADCAT UNLEASH V2 ATTENUATOR AND REAMP UNIT - Mixdown Magazine

mixdownmag.com.au

A clever problem-solver for amp lovers, the Unleash V2 earns strong praise for combining attenuation and re-amping in a way few rivals manage. The review highlights its realistic silent mode, smart reactive load design, impedance matching, isolated effects loop, and the ability to tame a 100-watt monster or beef up a smaller amp without sacrificing feel. It’s framed as especially useful for recording engineers and home players chasing cranked-amp tones at sane volumes. The catch: it’s not pitched as a universal must-have, and its real value depends on whether you actually need what happens “between head and cab.” Still, within that niche, Bad Cat’s attention to tone, safety, and real-world usability makes it come off as sturdy, trustworthy, and impressively well thought out.

Bad Cat Unleash V2 review | Guitar.com

guitar.com

A clever problem-solver with real gigging chops, the Unleash V2 makes small amps far more usable, letting you hit anything from bedroom volume to stage levels while adding genuinely handy extras: dual footswitchable volume presets, an FX loop, silent mode, headphones, and flexible impedance options. It’s compact, light, and especially strong as a re-amper/power amp for boosting low-watt combos with a drummer. The catch: it’s not the quiet, transparent attenuator some players may want. The cooling fan is now noticeably noisy at low volumes, and compared with simpler attenuators it can sound a touch brighter, thinner, and slightly fizzy. If your priority is pure attenuation at home, there are cheaper and arguably better-sounding options. But as a feature-packed live utility box, it earns its keep.
