I see the phrase "synthetic" thrown around a lot when describing ENGLs, even on this very thread.
And no offense to people who say that, but ENGL is a very varied brand with a lot of different sounding amps, and they aren't new, they've been making amps since 1985 so it's not like the Powerball was the first ever ENGL, even if it's the one most people got to play in the US. I can see the argument of "synthetic" for stuff like the powerball, fireball, maybe certain channels/modes of the invader. But that doesn't describe the Retro, Savage, Blackmore, Straight, etc.
It would be the equivalent of playing a Marshall JTM45 and saying "all Marshalls are low gain amps," while knowing the JVM and DSL exist.
Long story short, if you played a Powerball and didn't like it, I totally get it. But close your eyes or something if the brand is going to color your opinion, and go play a Savage, and I doubt you'd say ENGL's "all sound synthetic" after that.
*The only "gotcha" about the Savage Mk1 is that it's really a two channel amp. If you are on the Lead 2 channel, BOTH gain controls are active, not just the Lead 2 gain. I once had someone tell me their Savage was really dry and low gain on lead 2, saw the picture, Lead 1 gain control was set to 10 O'clock - no wonder! The Mk2 is more of a "true" 4 channel amp, but you lose the niceties of being able to manipulate the tone with both gain controls, which I personally like a lot.
Oh, and the repairs do suck ass. Circuit boards are mounted upside down inside and not silk screened. Kind of a dick move IMO, I've vented about this before but I do worry about very long term reliability (i.e. not now, but 15 years from now, will my 90s Savage be serviceable?). I guess it's not any worse than a gooped up modded amp though.
