Not sure on how much has been updated over the years, but that is a Maxon made FL9... I have a recent Maxon branded FL9 on my board, it's an awesome flanger for me and my tastes.
I have an old ibanez one, its pretty cool, very transparent. there are like 5 internal trim pots in it, dunno what they do, have yet to mess with them.
96.00???? thats a lot for a flanger. but it is a good one for extreme jet sounds. i sold two of those a while back. i like them better than most other flangers. i kept an ibanez cf-7 because it does that and switches to chorus in one pedal.
