Bleh. Gave up on my Green Day Songs.. I'm wondering. I've read some threads around here, and not really understood them so well, so I ask; If you were to have more than one cabinet, is it ideal to have another amp??? I've read the "bi-amping" thread and I understand that, but this is not what I'm talking about.. I'm thinking about if I were to say have.. 4 1x15" cabs, 1 4x10"'s, and a bunch of CABS hooked to the one amp, (all of course adding to the correct resistance, and pulling the right amount of power from the amp.. say everything is pulling 500 watts from a 1000watt amp..is this right?!) would it be ideal to use more than one amp-head?? Off the subject of amps.. Db (not D-flat ) is short for wavelength? Cheers !
