lol...yeah, I was perhaps a wee bit over-optimistic there, wasn't I? Ah, the bravado of the uninitiated. There's a lot going on with this thing, and it does take some time to get acquainted! While roaming through the presets, I found one (Tweedy) that, with a little tweaking of the drive and EQ, sufficed for rehearsal and sounds great with my 335 through my amp (Blackstar Club 40, with a 12" Celestion).
Then I downloaded the editing software...complete game changer! Using one of the empty User setlists, I recreated my current pedalboard's array, but then wondered if I could drag and drop other presets into my setlist. Yep. Awesome. So I dragged in about a half-dozen acoustic guitar presets, and at last night's rehearsal worked up a couple that fit really well with my little Guild Troubadour - including one that also works nicely with my mandolin. So, as of now my presets consist of a recreation of my pedalboard and two acoustic patches. If that was all I'd be able to do with this thing, I'd still be a happy camper as my gigging (and recording) palette just got a whole lot broader, but I've also saved about a half-dozen presets to tweak for specific guitars, so it looks like this thing is going to do everything I'd hoped it would.
If anybody's looking for me, I'll be out in the studio with a pot of coffee and a handful of guitars, building pedal arrays.
