Let`s face it,there are no guitar or bass do-it-all multi effect units that can please everybody,one does this better than the other and depend on your playing style.For what I do this multi effect is perfect,it`s got all I need in a small package.Made in Taiwan,solid build(Boss trade mark)with a stereo (dual)foot pedal you can call the banks up or down,the effects are very good,I specially like the chorus-delay,octave, reverb,wha,some of the Synth are usable,flanger. Is very easy to programm and/or tailor your own sound.It is an alternative to carry all your pedals if you don`t depend on effects too much,I don`t use effects on every song I play.I`ve been playing at home for over a month already without a problem.

I didn't like this multiple effects unit at all. It failed to work after a few months. Just blew out. I'm keeping my effects seperate for now on.

The delay/mods are excellent! The overdrive is creamy! The wah and expression pedal is fantastic! Best of all, it's practically indestructible! The only down side is the synth effects suck (not a biggie as I have no use for bass synth effects), and it doesn't come with a power adaptor or add-on footswitch for live performance. I don't use the compressor because I use a BBE 411 in my rack, so can't comment on it. The bass enhance is nice as well. I even like the defretter for smoothing. Be careful with the noise gate and master level, though, as they can cause your sound to "fall off" or distort. You should definitely buy the PSA power adaptor for it, and the FS6 add-on pedal for calling up presets for live performance is a must (although the FS6 is battery power only! Somebody tell Boss to add a power jumper for use with the ME series!). Great value and less stage clutter vs. individual stomp boxes!!

Pretty decent. Doesnt do anything extraordinary but is great if Bass isn't your primary instrument and you just want something basic to knock around with or to record with. Doesn't come with a power supply, which sux.

...you cannot combine any effects that are in the same grouping. For example: Flanger and chorus are both in the delay/modulation group and you can only use one at time, NOT combined.

Apart from that setback, this is a great unit. I love it. I would say go for the GT10B if you really need to combine effects like: compression and overdrive, or overdrive and distortion, or phaser and flanger - b/c again, you just cant do it.

while I was disappointed when I found this out, I still am very happy with it.
