I wanted a tube amp with glistening, bell-like cleans and tight, heavy distortion, with a budget of $600. On paper, this amp seemed to be absolutely perfect. In reality, this has turned out to be half true. The clean channel is absolutely gorgeous - crystal clear and smooth like butter. Honestly, I preferred the clean channel to even the Fenders in this price range. One of the few amps with which my guitar actually sounded great using the neck pickups (for some reason in most amps, my neck humbucker ends up sounding too muddy to be useable). That said, it can be difficult to get a crunch out of the clean channel at all but the higher volume settings - something to keep in mind if you were going for touch sensitive breakup. The overdrive channel on the other hand, has ultimately disappointed me. From the demo videos it seemed that the HT Studio 20 had a searing, cutting distortion that projected well and handled gain without becoming loose and undefined. No matter how much I fiddled with the EQ and ISF tone-shaping feature, the overdrive sounded like it was coming from under a blanket. The EQ and ISF changed the shape of the tone *under* the blanket, but for the life of me I couldn't get rid of the **** blanket. To my knowledge (and from my research) this unit was not defective and exhibited none of the signs of defect noted by other users. With my Schecter Omen-6, this amp sounds squashed and compressed and muffled. It sounds like there's a great tone hiding under the blanket, but it simply has no presence. The overdrive has been heartbreaking, because the build quality on this amp is absolutely superb, up there with some boutique manufacturers. It's a very manageable weight, and boy does it get LOUD if you need it to, though it can also back down to a bedroom level and still have workable tone. Additionally, the digital reverb on this baby is pretty sweet sounding, ranging from a subtle spring to some Edge-like, cavernous echo. Honestly, I couldn't tell it was digital. My suggestion would be to try it out for yourself, and compare it to other amps in the price range, and even high-end models to get your bearings. The problem with the overdrive could potentially be the speaker - I tried an HT 20 head with a Traynor cab at a local music store, and it had the exact opposite problem - the cleans sounded muddy, and the overdrive sounded much clearer (but still squashed relative to other amps...). Hard to say really. Give it a try though - maybe you'll have better luck.
