New rig, thanks to A-Hole who totaled my car and Ampeg ss head. Still have my 4 0hm Avatar 2X12 which was at my Drummers house. Tomorrow, I have deal to pick up Alembic F-1x preamp in what appears to be great condition. Now, need an amp. Am looking at Crown CE1000 (gently used) Crown XLS 402 new QSC RMX 1450 new Stewart 2.1 used (trying to make that deal- may not be succesful). Have gotten mixed reviews on the Crown XLS and CE amps. Here on TB, some folks believe that the CE is not intended for use with bass. Others give differing reactions to the CE. The RMX is one heavey compadre, but our PA uses them and have heard nothing but good things. Is there significant volume diff. between the 850 and 1450? I would think so. Blues, Classic Rock band. We usually play with PA support. Medium/Loud drummer, 2 guitars with 40 watt tube amps, harmonica with 40 watt tube amp (I know, I know) and keys through PA. Any help appreciated.
