all right. now i've gotten all spooked out over the farting on my new SVT610hlf and i may return it/replace it while I can. I may take it for one more test run because I really liked the look and all tone of the 610(except for the farting notes past 1/2 volume). I must make a decision. I got two shows coming up with zero or limited PA support, so i got to be loud, felt, clean, powerful. I play in 440/4string, but need a rig that can take some "ron jeremy sized" notes! I want to 100% stick with Ampeg. I do really prefer the SVT cosmetics, but I guess I can live without it if I had to. upfront: The 810e is a no/go because it doesn't fit sideways in the back of my SUV (the 610 fits/barely) I need my backseats to carry other stuff/people and I don't want to lay them down. Additioanally the 810 does not fit underneath my stairwell (where i store my gear after shows) The 610 barely fits hieghtwise. My GK 1001rb-II head is 700 watts/only drops to 4ohms so I cannot mismatch impedences. Upon returning the 610, Here are my choices: Ampeg PR410HLF (big wooden, ported pro cab) 4ohm/600watts or Amper PR410h (built just like the HLF, but sealed/non ported pro cab) 8ohms/600watts or SVT 410HLF (classic look, ported) 4ohms/500watts or SVT 410he (classic look, sealed) 8ohms/500watts. I could stack this on my 15e I already own. or SVT 15e (classic look, ported) 8ohms/200watts. I could stack this on top of the 15e i already own, but I kinda just want to keep that 15" at rehearsal only. HELP me choose!
