overall this is a good pedal can get mulptile sounds out of this pedal. good quality (well it is a boss). the sliders are good. don't leave the cables pluged in or your battery will be dead the nexy day. can't see myself playing without it

...then get this pedal!!! Other than playability, I feel that the tone that a bass guitar produces is what really makes it a high quality instrument. I am an experienced musician who has just recently started getting back into playing bass. I picked up a Rogue LX200B Series II Bass Guitar, which by the way is an excellent bass for the price. However, it didn't take long for me to realize that the pickups did not produce the amount of output that I would have liked. I decided to buy this pedal in hopes that it would boost the output of my guitar and it did more than just that! It made my bass louder and produce the kind of tone that you could only get from a bass with active pickups and electronics! So, if you're a bass player on budget like me who can't yet afford an Ibanez Soundgear or an Ernie Ball Stingray, then GET THIS PEDAL! You won't be disappointed.

I bought the GEB-7 a few weeks ago (I was in dire need to buy something new, as I hadn't in what seemed like an eternity). As soon as I plugged it into my rigged and dropped the mids into nonexistence I noticed an immediate (if immaculate) difference. The sound that I recorded my band's debut album with sounded paltry in comparison to my new, crushingly intense tone. With a good bit of distortion and the GEB massively scooped my bass sounds as if it's running through Dime (of Pantera)'s rig. The sound and the difference is massive.

Oh, and it's great for everything, not just metal. It can pump out some great dub and reggae-style tones. This thing can improve any rig, guaranteed!

I switch between a P/J Bass and a Dean Pace electric upright. If it weren't for this pedal, I would be a slave to the soundman. Instead, this pedal allows me to have my standard bass sound, and with the click of a switch, have my upright sound dialed in right there. This is a GREAT value, and the most important pedal I have next to my tuner.

because this pedal can be really noisy if you boost any frequency, I actually use this sparingly to cut my tone, then I can turn it off and my sound just hits you in the colon, not what I intended to use it for but its turned out to work great as a volume cut because I don't like the fading volume of volume pedals.
