MGR/Erik L.'s review"Boss Pro GE-21 Graphic Equalizer"

Boss GE-21 Graphic Equalizer
Bought it from a friend for about 75 euros. I think it's not made anymore ...

It's BOSS, it's a 21 bands equalizer, ... You can give your guitar and amplifier a new dimension with it. I wanted to buy a 7-bands pedal but this thing is so much better, 21 bands in a half rack with an on/off footswitch as option, GREAT !!!
For the clean channel you can shape your sound very well, but most time I use it on the overdrive channel, you can go through extremes !!!

When you turn it on, there's a lot of hum if you set the highs a bit more than normal, but with a good noise supressor there's no problem anymore.

It's not made to throw with but it is sturdy enough best place it in a flightcase, I made one for it by myself. But it's boss, so don't worry.

Nice EQ-unit, good sounds, Boss, 21 bands, ...

Boss GE-21 Graphic Equalizer
21 bands Equalizer small handy and small. Mono, 2 levels of choosing between rear.
Format 1 / 2 rack peret to anything with a compressor.
Jack Connectors, practice.


Use simple, normal.
No need for manual, equalize it!!


I use this on a bass or a guitar to give a sound clearer.


Trs good quality price, hlas is no longer available.
I have other more expensive eqs that bring me the same thing.
Used 3 years, I am glad trs.
