It is a clone of the Colorsound Power Boost is the analogue of which will boost the fuzz (with the gain pushed) through the overdrive.
Compared to the original version, a master volume was added.
It's pretty simple to use, volume, gain, bass and a knob of another treble.
Quality is to go, we have a clean boost, a treble booster if you boost the treble, overdrive or a fuzz when you push the beast, it's "vintage" and the possibilities are pretty huge.
It's excellent with humbuckers for sounds to Jeff Beck for example.
The pedal operates quietly significant, we can use it to push an amp to its limits and to saturate, or to bring sparkle and presence to get out of the mix, it can also increase thanks to the knob of his serious without falling into the muddy
This is the 4 pedals in a (clean boost / treble boost / overdrive / fuzz), with eq very effective, very good copy of the Colorsound Power Boost once used by David Gilmour and Gary Moore ... Jeff Beck n ' is not far as it used 9v version known as the Colorsound Overdriver.
It is very versatile, but with a vintage 70's soul good.
