Hey Stan... Cary, good to see you guys...
Here's what I think on the speaker issue:
I belive that the speakers do have a great impact on the sound... of course... But as long as I'm inside the sound, conserning listening to the different freqs, the snarl, bite, edge, mids, highs and lows... I can pretty much use any speakers, as long as I use the SAME ones during the testing... The speakers are different... but at these low levels, the differences would only be the final produced sound, that is made with in the amp... I mean, it's quite easy to distinguish the sound eaven if I played threw stereo speakers ( over doing it a bit

), as long as I use those same speakers from test to test. When that is done, I would say; find the right speaker that can nurrish the sound in the way you want... make it work like the final sound you hear on the demos... put a mic infront of a cab and record it... listen, and deside if the speakers are right... either way, the sound from the amp will come threw... If I lack some highs with in the sound, the distorted sound, I will hear that on allmost any speaker... as long as I have been using that same speaker threw out all the testings... I have a 65 or 75 watt celestion speaker ( from a JCM cab, I think )... sounds awefull, but even now and then, I plug it in just to for fun... I hear all the same thing from the amp, as I do with the green backs, different ballance, of course... but it wouldn't make me want to change anything in my amp, if it got uggly, cause if it did, it's quite clear that it's the speaker that's wrong, not the amp...
That's what it's all about... finding it in the amp... what kinda distortion... where the snarl is...if the bass is muddy... and so on...
The speaker are very important, but they do not shape the sound inside the amp... they let the sound come out in various ways... it's more like turning up or down the eq's on a stereo... warm enough, harsch enough, enough lows or highs... how you want the allready made and done sound to come out... hell, that's the reason for using eq's after the amp into a powerstage... to be able to adjust the FINAL sound from the first amp... if needed...
I feel the 30 watters have a bit more clairity, a bit bigger sound than my 25 watters... but that don't effect, or have any impact on the type of distortion I have inside my amp... just a different way to bring it out...
Great discussion, though
