I'm at BOTH ends of the spectrum.
I have purchased guitars without ever seeing them in person! I played two Guild F-50's in two local stores, and I loved the tone and feel of both!
(it's REALLY hard to find them here in So Cal!) One was an older Westerly, R.I, and one a newer New Hartford, CT. But I played each one twice, for about 10-15 mins. They were WAY overpriced, the older one in need of a neck reset, the newer one mint condition...but neither had a pickup. And neither dealer was willing to budge off the price, because "they don't make 'em anymore". Not being in a hurry, I did a TON of research online and found exactly what I was looking for at a decent price from an online retailer (with an outstanding reputation and a reasonable return policy)...even though it took months to find! (and those other two guitars are STILL at those stores!) But I could not be happier! Got a better guitar than either of those and with the DTAR!
On the other hand, at one time I was on the hunt for a new or used Gretsch , went to a few stores. played a bunch of guitars, didn't find anything that really "spoke to me"...then on the way out of one of the stores, my g/f says..."hey, look at this". It was a gorgeous hollow-body electric guitar, very much like a big-body Gretsch, but the name on it was Carlo Robelli, and I didn't even want to touch it! (what a snob!). But I noticed that it still had all the protective clear vinyl on the pick-guard and TRC, and a no fret-wear wear and not a mark on it anywhere.
So, to humor her more than anything, I pick it up, strum a couple of chords, did a real quick bridge re-set (floating bridge) and action tweak...and I was just flat-out AMAZED! Sounded and played just amazing, both acoustically and electrically...and this was with old strings! When I asked about it, no one in the store knew much about it, other than it came as part of the inventory when they bought out another store (it was NOS from the back room). I still didn't buy it...cuz of the name on the headstock.
Continued on looking at other things, but THAT guitar kinda haunted me! LOL! So when I got home I started to do a bunch of research on the Carlo Robelli RB-1955...which turns out to be made by Peerless and was actually designed as a Gretsch 3131, but when Fender took over Gretsch, they nixed it, so Peerless offered it up and Sam Ash (Robelli), Peavey (Rockingham) and several others snapped it up. An amazing guitar. In fact, Peerless STILL makes this guitar under their own name, the Peerless Gigmaster Custom.
I went back the very next day and bought it! That guitar is my main electric at all my gigs and here at home. Its a dream to play and I get SO many comments at the gigs!
So...sometimes it pays to wait, sometimes you just gotta "go with your gut"!
