hey guys, i'm doing a coffeehouse with my gf's group, and i'll be bringing out my Alessandro head & Acme B-1 cab. problem is i wanna make sure the signal i'm sending to the house PA is the same signal from my Alessandro amp, cause yea, it sounds that freakin' good! and also, it lacks a DI out. i would use my Demeter Tube DI, but i wanna let my gf use it for her acoustic. dya think, i could use a H&K RedBox or Palmer PDI-09 in between the amp and cab, so i can send the alessandro'ed signal to the house board? or would these mostly "guitar" oriented DI's not be good for my bass tone frequencies, especially my Low B? is there another box i can do this with?
