at 17 sec in to the song you can see him using a wah or some envelope filter with a foot pedal? You an see his foot moving it. I remember seeing the band in the early 80's and I thought it was Brent. Love that mushy gooney bird vibe!

John Cutler had modded a phaser around that era so its sweep (depth) could be controlled by an expression pedal instead of constantly cycling back and forth. Great sound. You can accomplish this on the AxeFX easily enough. Very cool little mod.

Nobody seems to know for sure which phaser he modified, but you can reach John through CAE and he may give you some details, if he remembers -- which you can share with all of us :shock:

If definitely an Ibanez, probably a PT-900 or PT-707...

There was an early Ibanez phaser that was built into a wah shell, but it didn't do a manual sweep (maybe unless it was modded).

Why would any effect be put into a wah shell if it wasn't going to be pedal-swept?

The pedal acted as a speed control, like a Rotovibe. It didn't do a manual phase shift.
There were a few similar pedals that had a switch that let it do both, but not one that Ibanez made AFAIK.

There's a pic from Day on the Green (Oct '76) which looks like an orange MXR phaser in front of Weir's amp.

In the early 80's, Weir used the Ibanez UE400 which had phaser. Did he use that phaser? I don't know.

In '78, he had the UE700 which also had a phaser. Again, I don't know if he used that phaser.

Other than that, I'm not sure what he used.
