Darn, it's tough not having a Two Rock dealer in town! I'm looking for a small amp and honed in on the Two Rock Jet based on soundclips I've heard and what everyone says about it. However, I'm undecided on a few things: 1 -- Standard or Signature? -- I've read that the main differences are that the Signature has mid and deep switches as well as better reverb. However, not having heard them side-by-side, I have no way of knowing if the plusses are significant. Has anyone tried to compare the two? 2 -- Combo or head + cab? -- I like the convenience of a combo, but have read that people think that the combo "limits" the capabilities of the Jet. Is that the consensus? Also, I've read that some people use their Jets through 2x12s. I had assumed that because of its power, that a 1x12 will suffice. Does it sound better through a 2x12? 3 -- If combo, then what about the Jumbo Jet? -- I can't find anything on the website about this. All I've heard is that the combo is bigger and has a 2x10 speaker config. Does the bigger box make up for what people earlier felt was a box that limited the amp? Thanks!
