I can recall three guitars that I truly regret letting go.
3) 414 LTD Walnut

Those are sweet boxes and it must hurt:-) The 414 is particularly interesting ... looks like the previous 8 series curly maple binding? They frequently pack some serious value add in the 4 LTDs (sometimes).
My biggest regret is an old d28 ... I like my last ((current) 816 tone better, but so much of what I play was originally recorded on Martin dreads, I have been looking to add another one. BUT I have yet to find one that has the missing tone, nor the playability of my Taylors. I played a 710 that almost was a worthy compromise. But that one slipped it off with someone else before I could rally the troops (my in house accountant). Lately I've found some very nice Eastman's in this category - the tone is different really though, and though I. almost like the tone better I'm worrying I will be back out looking at more traditional dreads. Would love to find a Taylor that had that sound, def don't care about the label.
