Hey everyone, Long time lurker, first time commenter. I've tried the Ampeg V-4B & fell in love. I currently have an Ampeg SVT HLF 610 cab in my possession. Unfortunately, I could not test out the amp with my cab. I've dug around these forums for help on whether I should get it or not since my cab is 600W and the V-4B is 100W. I couldn't really find a definitive answer to my particular question which is: Will I be able to be in control of the overdrive that occurs when you crank the V-4B? And will it be loud enough (without being overdriven) when I'm playing in a band for rehearsals/backyard/theater gigs? While I love the overdriven tone, I would also want the option to be clean without sacrificing my volume/getting lost in the sauce (aka the mix, when playing live). Also, the weight compared to the 300W tubes is much more attractive. I'm afraid of (potentially) messing up my speakers—or the amp for that matter—if I have to push the V-4B to the limit in order to be heard. My primary bass is a 2006 Fender Jaguar, so it has an active switch (not sure if that matters). I usually play Alt Rock/Punk/some Metal w/ two guitarists, sometimes a keyboard, and a very loud drummer. I'm really hoping this amp & cab will cover the playing situations I listed in bold above. I'm also ready to get my heart broken if you all think I should go with a different head for what I need. Thanks!
