Sorry to all you lovely db'ers but I meant acoustic guitar. I am playing a martin dc1xe with a Fishman pre in the guitar. Do cheap di's do the same as more expensive ones? At the minute I can't afford to buy a Phil Jones acoustic amp, which has a simple bass mid and treble control. But until then would a di be as good a purchase or buy a pre with the capability of a di, what are my options for those?
