BENSON 424 MKII: 4-Track Channel Strip in a Pedal

Nostalgia Made Pedal: Where Tape Demos Come Alive
The Benson 424 mkii captures the raw, characteristic essence of legendary 4-track tape recorders, translating the soul of the Tascam 424 mkii into a guitar pedal. Designed for those who grew up making cassette demos, this pedal delivers that warm, character-filled distortion of slow, spartan opamps but with modern portability and versatility. It’s not a perfect emulation—it’s a celebration of the imperfectly charming.

Its magic lies in the dazzlingly low input impedance that loads down your guitar pickups like they owe it money, delivering that vintage, compressed sound. But we understand that high frequencies and proper impedance bridging have their place too, so we included a switchable buffer circuit. The result is a sonic journey that starts in clean boost village, travels safely through distortion forests, and climbs fuzz mountain without breaking a sweat—all with 18V of internal headroom for when you need to punish an amp.
