In like new condition in original box with all materials included.  This is one of the most versatile attenuators available. See the features below. Transform your rig into the ultimate setup for practice, stage and studio.Back in 2012 when Bad Cat released the original Unleash, it was the first device of it’s kind. The worlds first re-amplifier booster / attenuator. This Unleash would take any amplifier from 1 to 100 watts and transparently attenuate or boost the signal. With the Unleash any amp could go from whisper quiet in the bedroom, to 100 plus blaring watts in the club. Now Bad Cat has released the first upgrade of it’s original groundbreaking device. The Unleash V2. Improvements include , switchable input impedances, for 4,8 and 16 ohm amp outputs. Silent recording switch, and headphone output. The general operations of the device include:Boost The Unleash V2 is very simple to use in application. To boost, plug the speaker output of your low wattage amp into the unleash input and the output of the unleash into a speaker cabinet. Set the input impedance to match the output of your amplifier. Now you have your favorite small wattage amp with the tone intact and 100 watts of available power.Attenuate How often have you wound up the gain on your 100 watt fire breather, rolled back the volume on your attenuator and hit the front end with a booster and got nothing? It just got dirtier with no appreciable boost in volume. With The Unleash you have boost to spare without changing the tone that you took so long to dial in. Having two channels to switch between affords the ultimate clean boost. Try putting an EQ in the effects loop and the tonal shaping options expand.Transparent Reproduction The unleash V2 leaves your tone intact like no attenuator that has come before it. The reactive load circuitry fools the tube amps output section into thinking it is still reacting with a speaker cabinet. It will bloom and squash just as if you are plugged into your cab.Effects Loop The unleash V2 has an effects loop. The effect is sitting post tube power amp and in the position to deliver a studio like effect to your live sound. Try placing an EQ after your favorite amp and open all kinds of tonal possibilities. Silent Record/Direct OutThe unleash come with a direct out to record or send to a board. Silent record switch disengages the Unleash speaker output . The Unleash V2 Reactive load circuitry will act as a cabinet for your tube amp , you won’t need to plug your amp into a cab. This feature is useful for those late night recording sessions.Foot switch (available separately) The foot switch allows you to have two volume controls, which can be switched back and forth with any single button channel switch pedal.
