I'm running through an ENGL E212VH, which is the 'Pro' one and has V30's. I'm sure it won't suit everybody; the Blackmore is very 'HiFi', in a way.
Through the same cab, the Switchblade also sounds great (although maybe not for everybody). The first time and many times actually, I played the Switchblade through an Tech21 4x12 cabinet, and didn't really get on with it. I couldn't get cut without icepick.
With the same cab Engl cab, the Blackmore stays tight and is very precise. The switchblade is more hairy and raw, but ballsy as hell (they both are). Actually, with my CS equipped PRS McCarty, the SB immediately reminded me of John Sykes' tone on 'You're gonna break my heart again'.
Not a lot of usual information there, I'm afraid. The best bit of information is that cab & speakers really make a difference; sometimes a head and a cab really just don't suit each other.
