Well, I have to say, I am absolutely astonished at the difference in sound now!
I do apologise for the REALLY REALLY poor quality of these clips - I just wanted to get something rough and ready down that would show the sound. I'm not bothered that the playing is scr@ppy, you'll just have to trust that I can play better than this ;)
Also, the microphone is really poor quality, but you'll get the idea from listening to the clips (I hope) of just how different these speakers all are.
The clips don't give the impression that I get stood in the room, though - there is MUCH more power on tap. The sound is fuller, fatter, more articulate and louder. I love it!!
Thanks for the suggestion of the G12K-100s to go with the EVMs, these speakers really do pair up well in the cab, as the EVMs are very neutral, and the G12Ks have amazing grind to them.
Also, I have deliberately left out my effects and noise gates and so on. Don't need that for bedroom volumes anyway.
Also 2) these speakers are NEW out of box, first time playing, not even remotely broken in yet!!
Without further ado:
Peavey 5150 Sheffield 1200 speakers, stock in 5150 cab. Well broken in. EVM-12L Black Label. New out of box, not taken to volume yet. Peavey Celestion G12K-100 speakers. New out of box, not taken to volume yet.Setup for recording (I make no apologies about the clean sound quality - I deliberately avoided all effects to make this comparison as clear as it could be):
Ibanez RG470F/TBL with Miracle Man Bridge pickup > Peavey 5150-II Head (all settings the same for all clips!!!) > Speakers > T-bone cheapo mic > cheapo work laptop.
