Ok... this is my dillema... i have a gig coming VERY shortly, and im in need of a bigger rig. A fellow band member is letting me borrow an Ampeg BSE410hlf (400 watts, 4 ohms). I was originally going to put it on top of a Crate 15 in combo, but that amp sounded bad in general and it was waaaaay underpowered (only 150 watts, i had the gain and master full blast, which gave me the ugliest tone i can imagine... and i have to compeat against a full stack AVT150). So im thinking of using my little Fender Bassman 25 for a preamp, running it out to an old Pyramid 600 power amp from our PA, and then putting that into the Ampeg. Does this sound possible? I like the Fender, i like the Ampeg, i just dont know how to get it all done, since ive never worked with pre-power setups before. The Fender has a 'line out' and an 'enternal speaker (which says 25 watts at 8 ohm minumum)' jack, so i thought about running from the line out, to a single side of the Pyramid (300 watts), then out to the cab. Any advice??? Sorry if i seem dim-witted, ive never done this before. Thanks for any help! Peace.
