Stock is most definitely good enough. Case in point: yesterday evening, I ran sound for Reb Beach (of Winger, Alice Cooper, Dokken, Whitesnake fame) and his band. He also played my own DSL100 head and '80 JCM800-badged 1960B (with G12Ms and G12T75s). He was playing his Suhrs into a Boss tuner, Suhr Shiba Drive and MXR mini Carbon Copy in front of the amp, and an always-on DD-7 in the loop. And sounded INSANE. For sure, he's a world-class player and has been for 30 years, but that was one of the best rock tones I ever heard in my life. And coming from a rig I've been gigging for 10 years (actually re-biased the amp on Sunday for EH EL34s), so no mod whatsoever (apart from swapping tubes, that is). And he commented on how fat the amp sounded. BTW he actually specifically requests a JCM2000 DSL100 on his rider. Guess it's a known quantity for him, and he's confident he can sound good on them. Which is a major understatement. So yeah, he (and Nuno Bettencourt, amongst others) uses the DSL100 and sounds god-like on it, and he's one of the biggest 80s guitar gods still around these days. Boosted DSL100/Lead 1 definitely will get you there.
