So i've recently picked up playing bass after a few years of shredding licks on the guitar and i've finally decided to throw some money down on a bass amp. I've got a few options that have been laid out before me and i'm looking for some professional/informed advice about what I should choose. Ampeg B-100r $450 ($375 US) This used amp sounds awsome and will fit well into the role it will be used for. But is $375 too much for this amp? it is in great looking and sounding shape. 30 day warrenty. SWR workingman's 12 $419 ($349 US) This used amp is the older style of the Workingman's 12 but sounded pretty awsome. It had some bite to it and would also fit into the sound of our band well. 30 day warrenty Ampeg BA-112 $365 ($304 US) This is an amp on clearence at a music store as the store doesn't deal ampeg any more. It is very nice sounding, although abit quiet, but it was a floor model, so it should definately be considered used. Comes with 5 year warrenty though. Carvin PB-300 w/ 2x12 Cabnet $325 ($271 US) This is our current amp that was borrowed. It doesn't have quite the nice sound we want, but it does the trick. Any advice would be greatly appreciated and considered.
