The reason why E-H changed the circuit over the years is that the main chips used in the old version haven’t been made for decades. Undaunted by that inconvenient fact, I gave the old circuit to our chief engineer, R.G. Keen, and asked him to figure out a way to use some equivalent chips to work in a similar circuit to re-create the sound of the Electra pedal. It was a tall order, but he figured it out and after a few tweaks, we had the Garagetone Oil Can Phaser and yes, it sounds just like that old Electra Phaser from the 70’s.
