BOSS DI-1 Direct Box Guitar Pedal - Professional Passive DI Box for Live Performance & Studio Recording - Perfect for Guitar, Bass, Keyboard & Audio Equipment (Black)

Boss is recognized for producing some of today's best musical gear & the Boss DI-1 Direct Box is one of them. I know this as a fact because this purchase was made because I have already been using one that is 8 years old & used night after night of performances. THE GOOD: Everything about the design & functions will enable you to (A) do the job of transforming hi-impedence signals to low impedence signals (B) the ground lift, phase & db switches will eliminate any issues of noise you may be getting from "dirty" electric (C) the unit itself & components are road tough. THE BAD: The only issue I have is the fact you have to unscrew 4 small screws on the bottom & slide the unit from the housing to replace the 9 volt battery. This is only an issue if your mixer or amp doesn't have 48 volt Phantom Power.=========================== GREAT PRODUCT ===========================================
