Original signal path of the 2nd generation, (1978 - 1979) A / DA Flanger with the following changes:
The reissue is true bypass where the original was not.
The PC Board has a slightly different layout but retains the original signal path.
As of 2014 the A / DA Flanger still sports original NOS Panasonic bucket brigade chips but the supply is running down.
It makes me feel young again. Although the A / DA Flanger wasn't released until 1976, (the reissue is of the 2nd generation '78 / '79 version), it remains the only flanger pedal that sounds like it was built to reproduce the studio flange effects used during the psychedelic '67-'69 era. The flanging effect of this era was more about a metallic shimmer or spacey mix match. Phasers sweeped or swooshed while flangers shimmered. Other flanging models released in the late '70s / early '80s, (maxon / Ibanez), used flanger tones but more phaser like controls. Their sweeping sound relates more to the '80s. I'm a "Lucy in the Sky with Diamonds" kinda guy. The A /DA is perfect for me.
The A /DA reissue may be on it's last legs. The NOS Panasonic chips are running out. I wouldn't order a new one without getting a guarentee on the chip being used.
If you were born after 1970 you may have a different take on what a flanger should do and the controls it should feature. Four knob Ibanez FL9s actually provide more direct control than the 5 knob + toggle switch of the A / DA. An Airplane or EVH swoosh type flanger, (that Eddie used more like a phaser), offers more direct control. The A / DA, (being a reissue and remaining true to the original), does not offer "next generation" control. It's true vintage quality may not work for '80s affectionados.
So far so good. I've been playing the hell out of it for a couple of months and it works as good as new.
I've had no need for customer support so far.
