Our all-rounder all-valve pedal preamp: ready to breathe new life into your guitar amp, pedalboard or recording rig
V4 The Jack is a two-channel, all-valve pedal preamp that delivers genuine valve overdrive. Use it straight into the front of your amp or recording interface, or alternatively use it in conjunction with your amp's FX loop to bypass the front end of your existing amp entirely for a whole new sound experience. This is definitely no 'ordinary' overdrive pedal!
The Jack changed from the Countess in late 2020 to better represent the versatility of the amplifier, it’s still the same amplifier inside and the changes made are purely visual and in name.
