For $550, the VH100r is a nice deal. I do kind of miss the one I had. It had 2 channels, each with 2 boosts (I basically treated it as a 4 channel amp).
The amp size itself is huge. I thought the clean was great. Distortion was nice too. It is a bright amp and at the time I had a bright 212, so that was not the best match. I kind of wish I could try one again through my current cabs. Lots of nice features on the VH100R, I would give it a go.
