This is a day late and a dollar short.
I have a friend who has a 65'ish twin. His comment about the Roadster channel 1 in tweed sounds almost like his Fender. Note: my cab is loaded with EV Black Label speakers. The only way I prefer V30's are with the Royal Atlantic 100.
Compared to the Mark V (when it was a head) he also liked the tone out of that too. I had since then converted the V to a combo (yes, also stuffed EV in there too). Just does not sound right with the V30's or MC90. When my friend was over last, his preference was for the Roadster.
Also had a Mark IV (now sold) No comparison to the Mark V. The tweed on the Roadster I feel is much better than the Mark V (tweed in the Mark V is terrible and harsh at full power, but sounds a bit nicer in variac mode). Too bad the V does not have Rectifier capabilities at 90W, at 45W it seems a bit lifeless. Roadster at 50W or 100W is a pleasure to play with. I love the character of the rectifier sag I get from the Roadster, seems non-existent with the V.
The two amps I use the most: Roadster (though EV cab) and RA100 (through V30 cab). Mark V basically took the back seat since I got the Roadster. Same thing happened to my Mark III when I got the Mark IV, as well as the Mark IV when I got the Mark V. I still like the V every now and then.
