I have been doing some gtr tracks this week and have been using 2 marshalls. One is a 1971 50w Make 2 lead amp. It says jmp on the front. The other is a brand new jcm 2000. The jcm shouldnt even be in the same room as the old one. I cant believe how whimpy the 2000 is next to the 1971. And the gain on the 2000 sounds like cheap dod distortion pedals compared to the 71. Volume wise the old one will kill you and you can feel the power coming out of the amp and it doesnt ever get to that crapped out thing. It just keeps getting louder. Right around 6 or 7 the natural compression is perfect. Even the meters on the board were amazingly more solid where as the 2000 had really hard peaks and then died quite a bit. In defense of the 2000 I did get a sound out of it that is acceptable and will most likely get used quite a bit cause the sound is all about big, but I can hear now that it will need a little more stuff than the other. The style lends itself to a good helping of FX, so that will be to my advantage I think. For tracking I have them panned about 9oclock and 3 oclock with some flange and cho and verb hard panned. Not to thick but you hear it... well. Panning them any harder seems to take away from the punchyness of the sound and the FX are just making it wider and bigger. I have the drums panned more center than that with a small room verb hard panned, so I think that too helps keep it punchy. FYI... I have them both running at the same time through a Radial ToneBone ABY box. This box is great.
