hey, so i just got my newish, 6 month old Taylor Academy 12 worked on, which is covered under 1 year warranty. adjustments, check, workup and new strings put on. i decided and perhaps regret putting on medium gauge. love the sound, am getting used to how much harder i have to press down, boy, callouses ever getting bigger fingers throbbing after 1 hour., anyhow, i noticed today when doing a slide on a riff i do, i can't slide well, makes no noise, barely, almost as if it's so tight it's just laying on the frets, so my beautiful two riffs i do which include slides in my songs, can't do them, sound like crap. suggestions, what to do, say to the store where i got it worked on...of course they will play and tell me it's fine, but it's clearly not.
