Hey i was wondering what multi-effect should i get? I have tried the ME50, i thought it was great, however i have not tried the Korg. So i was wondering if anyone could give me their opinions on which one to buy.

Cheers Cjb Scotland
I love the ME-50. I think it is simple to use and sounds awesome.
My Gear:
Gibson SG special (W/ S.D. Jazz(N) & JB (B))
Mesa-Boogie Solo Triple Rec. (with EL-34's)
Boss DD-6 Digital Delay
Boss TU-2 Chromatic tuner
(what else do i need)

Where i work:
I'm using my ME-50 now
It's a great pedal!
Make sure you get a PSU though as it tends to eat batteries
Epi Lp Custom-->Ernie Ball VPJR-->Visual Sound Jekyll And Hyde-->Boss TU-2-->Boss Tr-2-->ISP Decimator-->Dan-Electro Reel Echo-->MXR Micro Amp-->Laney VC-30 2x10

I'd go with the Korg over an ME-50. If you like Boss distortion, I'm sure you could find a used GT-6 in that same price range. The AX3000G is very versatile, you can check out clips on Korg/ToneWorks site that are actually accurate.
I own the Korg AX3000G, it's great! I highly recommend it.

I've heard that the Boss ME-50 is quite slow switching between patches which could be a problem dure gigs if you were using live. You should definitely try them both out first and decide for yourself.
i personally love my korg ax3000g. its very versatile, but it does take a little getting used to. At first i found it hard to get a good distorted sound out of it, but i worked with it, and tweaked this and that, and now in addition to some pretty sweet distorted sounds, i have pretty useful eq'ing skillz to go along with it ::thumbs up::

all of the common effects (reverb, chorus, flange, phaser, wah) work great, and all the specialized ones produce really interesting results (stuff like filtron, talk mod, etc.)
