Descripción en inglés del fabricante:
"The first re-amplifier and attenuator in one easy-to-transport, USA-made housing.
Unleash the world's first re-amplifier/attenuator. The Unleash Amplifier / Attenuator Booster will take any amplifier from 1 to 100 watts and either attenuate or boost, from whisper quiet in the bedroom, to 100-plus blaring watts in the club. Two footswitchable volume controls allow for rhythm and lead volumes. Unleash also offers an effects loop and direct out. Another first from the engineers at Bad Cat.
Boost
The Unleash 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. Now you have your favorite small-wattage amp with the tone intact and 100 watts of available power. Don't forget that the Unleash has an effects loop to plug that delay or chorus pedal into.
Attenuate
How often have you wound up the gain on your 100-watt firebreather, 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.
Sound Transparent
The Unleash 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.
Input Trim
When the input trim LED lights up, it is an indication of sufficient signal to drive the full potential of the Unleash output. Try to set the input trim to light up when signal is peaking. Feel free to push it harder. You cannot hurt it.
Effects Loop
Don't forget the ability to insert effects post tube power amp. Try placing an EQ after your favorite amp and open all kinds of tonal possibilities. The Unleash come with a direct out to record or send to a board while doing away with the necessity of plugging your amp into a cab. This is useful for those late-night recording sessions.
Direct Out
The Unleash comes with a direct out to record or send to a board. This is useful for those late night recording sessions. This direct out is a line level signal."
