Hello, I would like to understand the eq/spectrum workings of live amplification. If I play at home or rehearsal I know I need a almost flat EQ, with just a little bass boost. I play a Fender P. I assumed this applies to live amplification as well, but I think I may be mistaken. I have noticed that at the last Royal Albert Hall performance with Cream, Jack Bruce has a hill-like EQ curve, which would imply an emphasis on mids. I have also read somewhere that for stage amplification, the bass guitar actually needs a lot of mids. Besides wanting to have a good stage sound, there is another reason for my curiosity. I currently have two amps: a Peavey Mark III and a new Hartke HA5500. On the Peavey it says 1978 and 1980 so I asume it was designed in 1978. Using the same cabinet, a Peavey 410TVX, the Peavey has an aggresive emphasis on mids and seems to have no low end. The Hartke appears to have a more liniar response, and huge low end which makes everything in the room shake. However, I took the Peavey head to a gig, turned it up to 9 (of 10) to cope with a loud guitarist and a loud drummer and the mix turned out fine. I'm very confused: is the Peavey broken and has no low end, or was it designed like that because in a live situation you need lots of mids? Or was that the 70's general design, to give a midrangey bass tone?
