The sound of this distortion pedals used on its own is fairly neutral on the whole, not super aggressive, even treble the bottom. The serious, for against, send svrement. A substance has a distortion sounds like a vintage kind between ds1 and pushes enough overdrive. Personally, I use it as a booster plutt canal of a saturated amplifier lamps. L is your exact trs cool, we add just the extra gain, the sound becomes richer harmonics and sustain are especially emphasized (rglage level 10, gain 0 or 1, treble bass and 12h) and that, although respecting the sound of the amp. Trs diffrent a mt2 (quite aggressively) that imposes his personality that is a plutt complment add an amp or a little feeble to go solo.
Well, this is no longer manufactures pedals for a long time, this is a Japanese version, the serial number of APRS information on this site has boibote t fvrier factory in 1984.
I got in exchange of another faith and my pedals, pedals for-ago quarter century, not bad at all.
