I've had a GNX3000 for the past 7 years or so and had some decent presets on it over time. More recently in the last few years, I've developed a better ear for better tones and such and I feel like there are potentially better tones than what I can come up with on my own for this unit... I'm trying for a little more of a djentier tone, but I dont play full on djent stuff. I am aware of the MFX Supermodels CD that I believe is still purchasable, but I guess my question is, how do the MFX patches compare to some of the newer modeling technology out there like what Line 6 offers from the POD HD line? Is the GNX3000 worth investing in the MFX disc or would a newer modeling unit be a better choice?
