What's a di going to do for me at practice? With no PAFind a sound company that does PA for live bands. They usually supply everything you need for a live performance. Monitors, Mains and Subs. Usually pretty reasonable. 200/300 a night. The best part is they setup and tear down and run it for ya. A good DI would serve you better than running low end amps. Just shoot yourself through the monitor system. A good DI can be had for 200ish. Save up and get real equipment.
