I'm looking to spend around $300 on a pre-amp and I've narrowed it down to two contenders: Ampeg SVP-Pro and the SansAmp RBI In one corner, Allan Grossman chooses the Ampeg. Yes, how can I go wrong with Ampeg and it's classic tone? In the other, Bonafide endorses the Sansamp. Maybe more tone versatility here? I like the Ampeg sound but I want a "complete package" preamp so I can play everything from slow ballads to corpse-grinding metal. I'm definitely an all-around rock bassist. I've never done a poll before, so I couldn't resist.
