I gotta get some new gear for a band im joinin, and I came across the True Blue. I really like the semi-parametric EQ @ 5 bands. Can this be used as a preamp? I noticed that it had balanced/unbalanced ins/outs. Can I use those for an input from my bass? If not, I could go for the Sansamp RBI. But I really like the versatility of the semi-parametric EQ. Any help? If you havn't noticed yet, I'm kind of on a budget of about $300.
