The Boss GEB-7 offers proven quality and well-known design by Boss, as you would expect from Boss pedals. The chassis is made of solid metal, very stable and designed for live use. The Boss GEB-7 is a very useful reduction of complex EQ functionality to the main frequency bands for the bass in the rough live use on stage. It is specifically designed for bass players like me who want to achieve great effect with minimum effort, to invoke a certain sound character of the bass with one kick. Or quickly switch between freted and fretless bass without the need to tune the EQ of the amp. It is designed to tune the bass sound from subtleties and nuances up to radical sound changes and to give the bass player a wide range of flexible settings. With the GEB-7 you can bring out the best sound and each relevant character from the bass, from an earthy rock sound, via Heavy Metal or slapping up to a growling fretless sound. The Boss GEB-7 is also a very hot deal to make a cheap bass sound very much better.
