i've been fighting with this GT-100 all weekend, i don't think i'll be able to keep it. i can hardly even explain it, but there's really something odd about the A/D converters on the Boss. the response just isn't there somehow, it always feels a bit compressed or something. coming from the Mustang amps where everything just felt "alive"(with some fine-tuning), i just couldn't understand it at first. for days i thought maybe i just hadn't come across some hidden "sensitivity" setting or something, but one does not exist. after all i tried something just didn't feel "right" with the GT, so i did some basic testing earlier today. my 'benchmark' (i guess) is a modified version of the "Johnny Marr Clean" patch on the Mustang. loved that patch, anything i put through it just sang and broke up nicely when pushing up the Gain. so, that's what i've got in mind when testing the GT. i figured if i could get that, then more high gain, fuzzed out stuff should be no problem. just couldn't get the GT to 'feel like' the Fender amp models on the Mustang. on the other hand, i found that i really like the overall functionality as well as a LOT of the sounds you can get from the GT-100. overall, i think the tone itself is there, but it felt like the strings went up to 13s from 9s. i found that for certain styles of playing, this 'hard' sound worked great, even with the lack of touch. the GT really has a crisp, punchy sound and i think the high gain and od/dist/fuzz sounds are VERY flexible. i'm just not finding much of any of that 'subtle growl' that the Mustang does so effortlessly. the cleans are either too clean (and don't really grrrr when you hit it), or too just generally 'overdriven'. ... more to say, have to run for now. pretty upset with myself that i didn't make sure to try one out before going ahead with this. i was so impressed with some of those YT demos, i really didn't see this coming. i'll write back with more of my findings. now that i mention the strings, i wonder what would happen if i went from 10s to 7s or something. the thing might open right up!
