Carl:
Welcome to the club. You asked for a 6 stringer, and you got one. I have been bitten pretty seriously with AGAS (Alembic Guitar Acquisition Syndrome). I own your prospective guitar's older brother, a
'76 Series I, along with a
'77 Series i 12 string, a
Custom Further, an
employee shopnight strat, an Orion baritone I just bought, and several other guitars with Alembic electronics.
If the guitar you're looking at is in good shape, $2800 isn't unreasonable, even without a power supply, but I wouldn't go much higher. A new DS-5R rack mount power supply lists for $550 direct from Alembic, though you can likely get it for less if you order through a dealer. Your guitar originally came with a project box mounted power supply. Alembic doesn't make these anymore. They do show up very occasionally on ebay, maybe once every year or two. The 5-pin cable is $190 direct and again, probably less through a dealer. Sometimes members sell these in this forum. There are also others who can make this cable for you. Search around here and you'll find more info. I have a great purple 5-pin cable I got from Bayou Cables, mentioned on this site by another member. If your prospective guitar is wired stock, you can use it on battery power, but only the neck pick-up will work. It is an easy mod to change it so both pick-ups work in battery mode. Ask Mica at Alembic and she'll send you a schematic. If it has LEDs, they won't work in battery mode. Also, you'll go though batteries fairly quickly, so make sure you have extras and a little screwdriver in your case.
If you've never played an Alembic, especially a series instrument, you will be surprised by its clarity and punch, almost piano like. You will also find that you'll probably need to be a little more careful in your technique. Little flubs that aren't noticeable on a Fender or Gibson are very apparent on an Alembic. It seems there is a learning curve that just about everyone goes though when they get their first Alembic. It may be a little frustrating at first, but you will -out of necessity- improve your technique and become a better player.
Enjoy the ride and you may want to start saving your nickels and dimes for the custom you will invariably want once you become more familiar with things Alembic. This stuff is addictive - I warned you! lol
