I had one of these not too long ago but ultimately felt that the Darkglass Microtubes v2 900 was more my "voice". That said, I do miss the 7Pro. I know that Ampeg has their Classic analogue and combo SCR-DI pedals, but do they come close to the 7Pro? I've been watching for the Sushi box (SBVT) and Broughton's (SV-Pre) versions, but those are either a price premium/tough to come by.
DG and Dingwall go together. It is the bass sound that defined "djent". Not to say Ampegs don't work with Dings, just that most who get a Dingwall are looking for the Ding/DG sound.
The SV-Pre is awesome. If you can't find one that's affordable, I'd probably go with Sansamp pre instead.
