I am trying to decide whether or not to turn my older blue and silver IOD into an Ampeg SVP. I am a happy Alembic F-1X owner but having an alternate preamp with a very different tone would be handy. I love the IOD for it's cool design and fat tube compliment but have honestly never been able to tweak a very deep tone from it. My F-1X on the other hand is subterranean right from the get-go, is fat, rich..etc. Having the Ampeg would be cool for any full-on rock gigs I may fall into at some point and also for a classic dub-reggae tone I'm thinking. I know they are noisy but so many people use 'em, they can't be that bad. If any of youse guys can convince me that an SVP is deeper or "fatter" than and IOD I will trade this thing. Maybe I should try sticking a set of JJ's in there first....? I will never use it for OD, just for a fat, vintage snarl...like an old Ampeg! I use an Alembic F-1X, SF-2, QSC PLX 3002 and two EB-MM HD212's for my punk-jazz or deep dub material. Do I trade or no? Sure as heck don't want to kick myself for it later, the IOD is a unique and cool box; just don't use it much with the Alembic's massive tone. Is the SVP a tone monster or what? Thanks!!
