Anybody else here use the DigiTech GNX4 or the older 3 model??
I have a GNX4 which is kick-ass!!!
I went to the message board and got the MFX Supermodels Disk and upgrades....WOW

This is one serious modeler and effects unit!!
Right now, I'm running it through a poweramp into 2 cabinets...a 4X12 Carvin top and a 2X12 Custom Cabinet I got from HippieTim w/Celestions in it.
The onboard 8-track recorder is very nice..and the drum machine is better than any Boss unit I've heard. It's really streamlined my practice area...and I've improved a lot in a short period of time playing with backing tracks I downloaded and put on the soundcard of the GNX4.
I can't recommend this unit enough...
I recently got a really good deal on a GNX3 that I sold to a buddy of mine in Maine....I really bought it for him....I couldn't pass up the price...it's a bit different, but the sound is similar along with the features.
So, if you're looking for a great all in one practice setup, or even to use live, check them out...they are fairly reasonable on E-Bay...and with the Supermodels pack the sky is the limit on what you create.
