Bass Equalizer

The GE-7B is a 7 band Equalizer for Bass guitar. The design is very similar to the GE-7 but the frequency bands are optimized for bass guitar. The bands have center frequencies at 62Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz and 4Khz. There is also a level control that allows each band to be adjusted by +/- 15db.

The production moved from Japan to Taiwan early 1992.
