Prampli lights (4 * 12AX7) three channel (clean, crunch, ultra).
legalization for passive and active clean for both leads.
Between high and low gain, the rear connector complre, especially for the effects loop.

UTILIZATION

Simple, turn the knobs, you push the gain and it sculpts his sound quickly.

SOUNDS

This time it's a pramp for rock and nothing else.
I tried it with a Peavey 50/50 power amp.
The clean channel is not bad, except that with humbuckers the crunch quickly, so you have to play with the gain low (<4) or with simple microphones.
The crunch and ultra are similar, with a bit more gain on the Ultra.
The saturations are good, especially if you pull the knob towards you gain (+ gain even "pull gain").
The legalization is effective, with a pull to shift mediums, there is a wide range of sounds.
But the sounds are generally quite mediums, to have a dig its trs must activate the pull shift, lower mids -9 -12 or while pushing the bass and Aiges. Be careful even above 9, the low cause a "quagmire" dsagrable, and treble screaming deviennet trs

OVERALL OPINION

In the end this little prampli is nice: trs reasonable weight, simplicity of use, many possibilities To insert effects loop, but in the clear sound could be better, and the saturated mdiums has too much, and then gain a level not enough to balance me, voodu valve is better for it.
Nanmoins to make hard or mtal simple with good sound and without taking the head is a good investment trs
