OK...here's my situation. The bass player in my band is leaving for grad-school, now I (a strat-cat) will become a bottom feeder for the time being untill we can find a full time foundation layer with one guitarist and a drummer. I have an Ibanez 4 stringer (SG400?) and an inexpensive bass combo amp (Gorilla). The bass has treble and bass controls with separate volume controls for neck and bridge. The amp has a presence control with a three band eq, plus a mid and high boost switches. I already have a compressor and chorus pedal. My question: I want to create a full sound to round out the band when the guitarist takes a lead solo. Should I take my $100 from a recent gig and invest in: 1) A solid EQ unit. I'm thinking of the Yamaha NE-1, or a BOSS unit. 2) A bass octaver. And if so, which would you recommend? 3) An inexpensive muli-effect unit. I've seen the ZOOM and Korg, but both strike me as being very flimsy. Personally, I'm leaning toward the octaver. Option 3 makes me a little leary because whatever I get must be reliable. You may also notice I have no reverb, so I guess that may be an option as well. Let me here your opinions.
