Like with everything else that is guitar-related, it depends. I wouldn’t say that they are the best amps overall, but it wouldn’t be crazy to say that’s the case when you’re looking for a specific sound related to one particular genre. Bear in mind that I’ve never played a real Dumble. Still, I’ve played through a few clones, and, when you look around and see that lots of contemporary Blues players are playing Two Rock amps (or similar brands), that’s enough for me to say that an Overdrive Special is probably the “dream amp” for almost every Modern Blues player.
