I've tried both versions of the DS-1 and DS-2 ( in terms of Japan and Taiwan models )
basically, MIT DS-1 and MIT DS-2 dont sound good ( in my very honest opinion ). however, the MIT DS-1 is a better buy as compared to the MIT DS-2 as it has a whole lot more modding options to choose from.
for the Japan versions, I would say that the MIJ DS-2 ( they exist but are as easy to find as chicken teeth :lol: . ) totally kills the MIT DS-2. it has so much more gain and warmth. its so easy to get feedback out of your amp just by turning the distortion knob. the Taiwan version cant do that. basically, the Japan version has a hell lot more gain. very good for hard rock.
however, I personally prefer an MIJ DS-1 over an MIJ DS-2. I prefer it cos its more smooth sounding. I use it as a booster to boost an overdriven amp or just a GT-2. very "full" sounding in a way. since I dont just play hard rock, I decided to keep the MIJ DS-1 and sell the MIJ DS-2.
oh, one thing I like about the DS-2 is the external footswitch thing. can change between mode I and mode II. really good in a way.
