Great device for multi-amp bass setup
This product does exactly what I needed. I plug my guitar into the input jack, then run output 1 to a Hartke HA5000 and HX112 cab for highs and output 2 to a Hartke HA7000 and HX115 for lows. This way each frequency spectrum has its own EQ which enables much cleaner sound. I send output 3 to a tuner. The Boost control was a bonus, but comes in handy. One can use this control to adjust the overall volume without changing the overall tone. So far, everything is working and sounding great.
