Last Friday, I bought 2 vintage (1 from '74 and 1 from '80) Ibanez phasers from one of my co-workers at my summer job. Luckily for me, he felt the need to let go of them for dirt,
dirt cheap. Only 5 euros a pop.
Here are some pics for you that I stole off effectsdatabase.com, I don't wanna bother you with my crappy camera phone pics:
The one from '74, an Ibanez Phase Tone PT-999, according to effectsdatabase.com:
The one from '80, an Ibanez Phase Tone PT-909, I actually have the original box and manual with this one:
The one from '74 was broken, the battery clip and isolation material needed replacement, but I got it repaired by friends who work (and own) at a local guitar shop last Sunday (for free

) and now it works like a charm.
The one from '80 works perfectly and only needed a battery to fire it up. This one also has an input jack for a powersupply, but it needs a different kind of plug in than my 1-spot provides so I'll stick with batteries 'till I get myself a daisy-chain and a converter plug.
My friends at the guitar store also found out from what year the one-knobber was, as they had a book on effects pedals that included some info on it, including that this model was made in '74 and '75. The PT-909 had '1980' in the manual, so I figure that's the year it was made, which is possible, 'cause the same book said the PT-909 said it was made from '79 to '82.
They sound kind of similar, but very great, no tone-suck or volume spike/drop, just an added phaser, with a little bit of coloration, on top of your original signal. The PT-909 is more versatile, because of the added feedback and width control, but I believe the PT-999 can do a much faster phase than the PT-909.
They sound good with both bass and guitar, especially with some dirt before them/it, which puts some more emphasis on the phasing effect. Dirt after kinda kills the phasing effect, but not completely.
Great score, no
