Well, I finally completed my switch to all Ampeg. I have been playing upright for about 3 years and started playing bass guitar about 4 months ago. I'm playing more rock and blues now and really having a blast! Bass Rules!! I ended up getting an SVT IV-Pro and yesterday got a PR410-HLF to go with it. I played an outdoor gig yesterday and it sounded awesome! I couldn't resist cranking it (hey, the sound man actually asked me to turn up) although I relented and turned down a LITTLE when the guitar player whined "All I can hear is bass". Marshall be damned!! The drummer LOVED it though! He said he could feel the basswhile he played. Anyway, sorry to gush like this but I am totally stoked with my rig. One negative, the cabinet is HEAVY!!! I guess that's the price for sound though.
