ive got a ht-dual. i bought it to get a bit of valve action in front of the cheapy marshal mg30dfx amp i have, cos ive never really liked the tone of the thing.
i use channel 1 of the dual set to clean and the 2nd channel for distortion. id whole heartedly recommend this pedal if you cant afford a valve amp.
running my danelectro blue paisley overdrive into the clean channel of the dt-dual sounds great. ive also run my digitech hendrix pedal though it too (not extensively though) with no nasty hum issues.
ive since bought a fender champion 600 amp. it sounds great paired with this too.
