it's quite clean, also I have WGS 10" G10C/S 75WATT speaker inside which keeps the amp really clean even at high volume/gain. BUT, before I used boss blues driver which is not a gain heavy overdrive, I would say its kinda in the Centaur range and I could get all kinds of mild cruch to heavier overdrive with it at room/apartment volumes, using Minotaur clone in HX, setting level to unity and gain to 10 I get only slight crunch, maybe a little bit more when I hit the strings really hard, seems weird, I dont know, maybe thats my setup's character? Also I notticed that some of the drives are not that sensitive to tone change on my guitar.
@codamedia 1. thanks for reply! yes I tried different cables, 2. nope no effects before drives 3. how to add dbs? you mean using eq as pedal in the chain?
anyways, I really like the unit so far, great effects
