Used GE-7 Graphic EQ in great condition.
Here is what Boss say...
'Boss Product Overview
The BOSS GE-7 Graphic Equaliser lets you shape your sound and eliminate frequencies causing feedback. Its seven band EQ ranges from 100Hz to 6.4kHz with a powerful 15dB boost/cut per band, this lets you dial in a range of tones, letting you stand out from the mix when you want to, or even blend in with other instruments more effectively.'
