Notice the little JHS volume box on top, that in the loop has made this all possible, I can get the tones I want at home volumes and they sound good, I'm using the 20 watt mode, no need for the 5 watt mode since I have the JHS, both modes sound good though. So a couple observations and a couple things I tried, jumping the channels is the way to go, plugging into each channel individually was either too fat or too thin, so I tried 2 ways of jumpering and got good tones all around, bottom inputs provide lower volume and gain and top inputs more. I find the sweet spot for me is both channels on 7, I get edge of breakup and dig in for crunch. The normal channel adds the amount of bass to your tone, the higher you turn it up the bassier your tone, the high channel adds gain, the higher you turn up the gainier it gets, 7 on both channels is perfect for me, I can play Zep and ACDC all day long. I settled on jumpering the high channel bottom input to the normal channel top input, the reason being I plug into the top input of the high channel with my Gibsons and plug into the bottom input of the normal channel with my Strat, this is what sounded best for these guitars. The loop works well, it doesnt cut volume when turned on its very transparent and no loud pops when turning on/off unbuffered pedals, I have the JHS volume box and an LPB1 boost pedal for lead volume boost in it, works well. Currently I've been playing it through my G12T75 2x12 cab, sounds good so I havent tried anything else, I will break out a pair of greenbacks at some point to try. The stock Marshall tubes sound good too I might just leave them alone, no hurry to try other tubes. For higher gain I have a pedal board with various ODs for varying levels of gain, they all sound good, currently on the board - GE7 for low gain, RAT for medium gain, ZW OD for high gain. I have about 2.5 hours on the amp at this point and have been happy so far with what I'm getting out of it, it could be a keeper! One thing though, its got me wondering how a 1959 Super Lead compares, at the new SV20H price I could easily afford a used 1959. What the SV20H has going for it though is it sounds good, is smaller and light weight, and has a good loop, those are all major pluses. Yup I've got 45 days to think about it, I might even order up a 1959 to compare side by side! So that's my initial review.
