FAS definitely cured GAS. From time to time I will check a guitar but rarely come to buying one. 5 guitars over 20 yrs : one Epiphone J200 (new - 1990), a jap strat (new - 1985), a (G&L Asat custom new - 2005), a Peerless NY (occasion - 2009) and Fame Forum IV (occasion - 2011). I occasionnaly owned an Washburn ES335 copy (new 1988), a Fender Mex Deluxe strat (occasion 2003) and a Danelectro (new - 2004). I had only one amp all those years : A Fender Superchamp, the old version and was so stupid to sell it in 2003. Followed for 4 years an endless row of amps, preamps and poweramps that crossed my place and were bought and sold over Ebay, until in 2007 I found again my happiness with a modded Fender Deluxe (combined with the Digitech 2101LE), it got sold after acquiring an Axe II early 2012.
For effects I always was rackbased, starting from the UE400 (Ibanez occasion - 1987), a Quadraverb (occasion 1990), a Digitech 2101LE (occasion 2002, sold in 2012) and an ULTRA (new)from 2010-2012. Further a tiny few stompboxes, the ordinary stuff : Wah, & disto).
The difficulty in the start with the Axe was FRFR amplification but I only bought and tried one amp, a new Traynor K4 that I'll change before summer for a dB Technologies FM12 as the K4 is too damn heavy. I'm too tired of trying out tons of amps again, what counts for me is to have the monitor function. The sound of the AXe over PA, even different and smaller ones, generally is "good enough", so all what counts is to have a "sufficient" monitoring.
Since 2012 the only thing I occasionally look after is changing PU on my jap strat and - an old dream - a Les Paul Custom maybe in few years from now, but I consider myself cured from GAS definitely compared to the "horror years" 2003-2007.
For reasons I don't know and what I understand from hereabove classic instrument players don't have so much of what I'd call a "learning and development curve" over the years. As an amateur I very slowly "grew into my instruments" and whenever I changed instruments it really was because I needed "something new", fresh sound to devellop my skills and sound abilities. PRobably for this reason only the instruments I bought were new, all the other stuff almost always was second hand stuff, except the Axe Fx and the K4. And when I change instrument, generally it's predecessor doesn't get played a lot anymore, but if the instrument was "good enough" for me I'll keep it for recalling old sounds/styles from time to time.
Ah....and I have it all in the attic, as I don't have a basement !
