I obtained a graphic equalizer for the bass guitar.
Because I am guitar of the band charge, many people might think use to musical instruments. It is different. This was bought as a base booster to drive Bodysonic system. that was buried it under the captain seat of the flight simulator. It was very ineffectual though a passive low-pass filter was variously made by oneself and had been installed. When 50Hz is done in the boost by immediately installing it, and other frequencies are cut, it is pleasant. Super Low Bass is power full marks.
