Micah,
I have 2 Soldanos. I have the Lucky 13 that has an incredible clean channel. It sounds almost exactly like my Fender Pro Reverb, and it has Reverb.
The Hot Rod 100 can cover any ground from EVH to Warren Haynes (who uses the SLO) to all out Death Metal.
The Clean channel is pretty good too, very articulate.
There is really nothing that I don't like about the Hot Rod 100, other than the shared EQ for both channels. Although, I can dial in really good tones in both channels with the same EQ settings very easily.
I was looking to get a high gain Boogie, and had a few guitars for sale. The owner was looking for a new guitar, he wanted my PRS, but I told him no. He really liked my US Strat Deluxe that was for sale, so we traded. I gave him the Strat and fixed some stuff for him.
In short, I have a great Soldano and would never use this amp. I really liked the Reverb and the Cleans on the Roadster and need something more versatile than the Soldano for possible future gigs. The Lucky 13 is incredibly versatile, as is the Hot Rod 100, but I like bells & whistles.
Jackie,
I used to have a Mark IV and tried one out next to the Roadster. The Mark IV didn't have as nice of a clean sound, and it has to be cranked to get where I want it. For my tonal preferences, it fell very short of where the Roadster was.
It's funny too, I was starting to think that I should get another Mark IV because of it's versatillity, but the Solo feature and separate EQ's for each channel sold me 100%. Plus, I love the Vintage/Spongy/Tube Rectifier settings.
As for weight, I think it's somewhere around 100 pounds. I could still lift it with 1 hand, but it would be a pain in the butt to lug around like that. It has side handles like the Tremoverb combo, and casters so it is really easy to transport.
I can't wait. I just have to sell some stuff on Ebay to raise the rest of the money.
