I just can't figure out how to get a tone like, for example, this: http://uk.youtube.com/watch?v=R3cXSNFeN9k Apparently that's Warwick Infinity-->Sansamp Rackmount Bass Driver-->Warwick Pro Tube-->Warwick 4x10 pros. So I thought maybe getting something like the Sansamp Bass driver would help( programmable, not rackmount.) Someone who owned one said that the overdrive on it could be compared to Chris Squire's tone. I don't know which song he was talking about, but I thought of Roundabout. The tone for these two things are quite similair ( or at least in the vein of what i'm aiming for). But, after hearing clips of what the Bass Driver sounds like, it doesn't really sound the same. In short, what's going to get me a nice growly tone like the clip I posted? Thanks for any help.
