Ibanez BPL Bi-Stage Phaser and Ibanez PH10 Bi-Mode Phaser

I have both Ibanez Phasers currently opened up, saw no topic on these pedals, so I took some pictures.
The Ibanez BPL Bi-Stage Phaser and Ibanez PH10 Bi-Mode Phaser have the same circuit and PCB.
Only the potentiometer types are different, values are the same.

After adjusting the Width trim-pot, VR4 1k Ohm, I found that the maximum range of the Width could be a bit larger so that the Phaser can "move" from more low to more high.
For this I changed R66 82k Ohm resistor, that is in series with the Width pot, on the potentiometer PCB that holds the LFO, into a 62k Ohm resistor.
Then I adjusted the Width trim-pot again.

Hello!! i recently got this, do you know what the feedback pot does? i think the one on my own doesn't work

The feedback pot takes the delayed signal from the output of the phase stages and routes a portion of that back into the input of the phase stages. The sound gets more resonance this way, making a more pronounced phasing signal. The difference between no feedback or max feedback should be quite audible.
