Turns out 60 watt Marks ARE faster!

Maybe I’m talking about a different thing altogether….what I mean is, plugging into and playing an amp, same guitar/pedals etc then plugging into another immediately (using the same exact guitar pedals cab) and noting how much faster the response is, in comparison to the first amp. Very noticeable between the two Marks I mentioned previously.

I'm with Tom here, I totally notice the speed of attack between various amps. To me an amp like the Engl Savage120 is the fastest amp I've owned, while something like a MW Dual Recto is very slow in the attack, feels very sluggish and doesn't keep up with playing thrashy riffs near as well...as one example.
