Twin 12ax7 tube preamp pedal

The PlexiVibe – Golden Era of British sound

PlexiVibe is an all-tube hand-built Overdrive/Distortion preamp guitar pedal.  Despite its relatively small size, it achieves versatility and various tone options, being constructed with 2 12AX7 tubes.

PlexiVibe, as its name implies, gives you that “Plexi” vibe and is not an attempt at MIAB, it is the real McCoy, producing sounds and tones reminiscent of the “golden era” of that British sound amplification.

Producing easily the most sought-after classic rock and hard rock sounds, PlexiVibe does everything from late 60s bluesy-inspired Plexi tones and goes through to more modern 80s modded Plexi sounds.
