The Handling is fairly easy. You can either use this device as a normal overdrive or distortion pedal in front of your amp, plug it in directly to your Power Amp Section as a Preamp or you can also send the signal directly into a PA mixing board, since it emulates a guitar speaker.
Six knobs: Low, Mid, High, Level, Voice and Drive. Input / Output and a connection for a power adaptor.
The Voice knob is the really interesting feature. It controls the shape of the mid frequencies. The more you dial in, the thicker the sound will get, ranging from early Mk II Sound to the super thick Hi Gain Sound of the latest Rectifier series.
This device is supposed to emulate guitar amps that are build in Petluma, California. And it does! I did an A / B comparison with a Dual Rectifier and it comes close, very close.
Like with the original amps, be careful with the amount of Bass you dial in. This pedal has LOTS of it.
The integrated speaker emulation cannot be turned off, although that is not a big deal, since you can compensate that with adding more High Frequencies.
When you dial in full Drive and full voice, it makes a very strange humming sound.
But in reality this is never a problem, because the pedal have tons of gain reserve, you actually do not need to turn it all the way up.
Therefore I tend to presume it's the Chinese sound for: Warning! Too much distortion.
From the outside this thing is built like a tank. The knobs are very easy to move, some will find it a bit too easy. The on/off switch is indeed positioned a bit close to the knobs, but that is no problem because it is elevated and you will not touch the knobs with your foot.
The only thing that is to criticize about this pedal is the battery compartment. The battery is to be clamped directly under the PCB circuit board. And that can't be a good thing.
