So I got mine about a month ago... and I just now figured out the best way to use it...
Got 80 User Patches right...? And I found the most "change" you get to any sound, other than of course the Pre-Amp/EQ Settings is the Cabinet Selection. So I've found my "Clean" Sound and the top 4 Cabinet Voicings I like with that sound, now that's my U-01,02,03,04... Then I get my PedalWah Effect, find the best 4 Cabs and that's U-21,22,23,24. Then my Flanger, Chorus's, Synths, etc etc etc.... Honestly if you can use more than 20 Different Effect Patches (mind you, most of the time you can have 2 Effects on 1 Patch) in one Gig, then you're Billy Sheehan or Stu Hamm! IMO, this is the best use outta this B9.1ut, Zoom's giving you all these different Effects, 'cause everyone likes different things. But usually, if you like Compressions or "Warm" tones type of Player, then you're not a big "Distortion" guy or vice versa. So do what I did, find you're 20 Best Used Effect/Amp Modelings that you like, then give yourself 4 Different Cab Voicings, or maybe 1 Cab and 4 different EQ Settings... Whatever floats your Boat... And make those your User Patches. You can always go to the P-Banks for the Factory (UnEditable) Patches. Or if you real F@#k Up, Just Turn on the Power Switch While Holding Down the Store Button. Return it to outta the box settings! Oh and BTW, GET THE LIBRIRIAN EDITOR SOFTWARE (& the MIDI/USB Cable obviously)!!! Rock On!
