I accidentally purchased this thinking it was the full Kraken V4 180W amp head model, so it has never been used.
A rock-solid, award-winning, all-valve pedal preamp ready to breathe new life into your guitar amp, pedal board, or recording rig.
The V4 The Kraken is a two-channel pedal preamp that delivers a full-blown all-valve overdrive. Connect it directly to the front of your amplifier or recording interface, or combine it with your amplifier's FX loop to completely bypass your existing amp's front end for a whole new sonic experience. This is definitely not your "run-of-the-mill" overdrive pedal!
All-valve signal path
Featuring one EC900 and three CV4014 amplifiers operating at high plate voltage, this is the first pedal-style guitar preamp with four valves and an all-valve signal path. This is not your average overdrive pedal!
2 channels
Like its namesake amp, Gain 1 is a little looser, with a more vintage British-style gain sound, while Gain 2 has tighter lows, more mids, and of course more drive.
Amp Thru Mode Description
Amp Thru mode uses the effects loop of your guitar amp.
When the pedal is on, it bypasses the front end of the amplifier.
When the pedal is off, connect it to your amp as normal.
It adds two new "channels" to your amp that are independent of the amp's front end. Imagine being able to feed the front end of a Countess, Sheriff, or Kraken into the power section of a Fender Twin. That's when your single-channel workhorse becomes a three-channel monster.
Can't use the FX loop? Use standalone mode to put it right at the front.
