I have a '98 Classic red/wine colored Fly and used to play it exclusively until I couldn't handle changing the 9V battery every couple of weeks; man, that thing
eats batteries.
It's not like it starts to sputter and dies suddenly; the sound seems to thin out over time and you get tone-suck and then start dialing in more low end/mids, etc. and wondering why it's sounding so thin, even though the flashing battery status LED in the back says the 9V is ok.
I have mods to rewire it so the magnetic pickups go direct to the output jack (like a conventional guitar) but have been advised that would hurt the resale value so I've not done that. I've been toying with the idea of selling it for years since I've playing Suhrs for some time.
I do have to say it's amazing to play and feels awesome...killer sustain, fantastic access to all frets up to the 24th, the best neck/body joint ever, light, ergonomic...it's so ahead of it's time in many respects that I feel guilty for not giving it the love it deserves, but can't bring myself to mod/re-wire it.
This thread made me pull it out today and have a play on it; I really need to either sell it or mod it.
EDIT:
Whoa! I see there is one on reverb.com...asking $5,500 CDN
