I thought DI is just for acoustic guitar signals....like a pre amp.
For that matter I dont use a DI for my acoustic either.
Why DI at all?

Here's the basic answer, from Whirlwind:
A “DI” serves several basic functions:
* It converts a high impedance signal to a low impedance signal (although it will also accept a low impedance signal from a preamp, keyboard, active pickup or other electronic device).
* It converts an unbalanced signal to balanced.
* It reduces a strong instrument or line level signal (and sometimes even speaker level signal) to a mic level signal suitable for connection to the mic input of a mixing console.
* It isolates electronic equipment on stage from the mixing console, which can help eliminate interference and noise caused by electrical interaction or ground loops. It also blocks phantom power sent from the mixer so it cannot interact with the the device connected to the DI's input.
There are two types of Direct Boxes, passive and active.

Personally, I've never needed one either, BUT I only plug
mics into the mic input of my board. My acoustic has an on-board pre-amp that handles signal strength, impedance, etc so I go straight into one of the 1/4" balanced inputs and am good to go.
