hey guys. this looks like the right place to ask this question. i haven't played live for about 5yrs or so, and the boys and i are playing an all-stars show in about a month. problem is, i've got half of a live bass rig. i've got a straight power amp, the bass, and a bass cabinet - put no preamp. i'm looking for a floor/stompbox unit that will give me voltage gain, so i can drive the power amp. i've looked at the sansamp DI box, and the MXR DI/distortion box. also saw a cheap behringer DI/modeler. they've all got gain, bass/treble, and distortion or modeling capabilities...but what i'm looking for, is if these units will actually amplify the bass input. i wish these mfgs would post specs like output impedance, gain and such. what is an effective, cheap solution for my situation? i just want to plug into my power amp and jam. any help you guys could lend would be much appreciated. thanks in advance.
