Phase 90, pot problem
« on: June 24, 2010, 06:17:55 AM »
Hi guys I've built the Phase 90 from Tonepad ( ).
I got it up and running but my problem is this: when I turn the rate pot all the way CCW it sounds like a tremolo more than a phaser (it really sort of beats) and if I turn it all the way up it goes from beating to constant.

I used this pot: could that be the problem (using linear taper instead of reversed logarithmic?)

I can adjust the trim pot and find a sweet spot for the sound so I guess the circuit itself is working?

It will likely work better with the reverse log pot!  Providing everything else is wire up correctly, that is  ;o)
