Sadly no, what do you need concerning this pedal/schematic ?

The 'manual phaser''rocker pedal feature.
How does it work?

Referring to this thread:
https://www.diystompboxes.com/smfforum/ ... ic=72152.0
I assume that you want to replace the LFO with a potentiometer like it is also done in the EH Bad Stone.

Which Phase-stages you like to control - FET-based, LDR-based or OTA-based ?

Modulation pedals / delays, all the pedals which aren't od or fuzz or distortion are a bit of a shoot in the dark for me.
I really don't understand much about them.
I thought I could do this simple conversion easily, I didn't think it would depend on the design of the phaser itself (ota, fet or led/lrd).

Hi, I have a working Morley PFA Pro Phaser, this is something it should already will do, the left hand switch allows you to change from altering the mod speed with the pedal or manual phasing. If you want any gut shots let me know.

on a physical level, inside the pedal doesn't operate a pot, a strip of material folded in an c-shape covers light sensors as you rock the pedal backwards and forwards, ingenious!

Hi, here is a clear schematic, I can't verify it is real though!

Can any pedal gurus tell if there would be a way of modding one of these to operate as a tremolo? I'd want to be able to switch between modes if this is possible, as this is a really cool sounding phaser

here you go, let me know if you want more shots, and what of?

ianZeds HEY man it is very kind of you to answer me.

thanks man.......
this thing have two transformers!!!
...and yes if I can ask for some more photos.......one just like this one you posted already,but taken from 90' angle....like if you just put it on scanner.... other photo is photo of part with 6LDR-s ( behind that peace of cardboard?).......and if you can please comment on how this phaser sounds......and tell us (me)

about LFO of this phaser....your impressions...........................and I could not find sound demo of it enywhere on net,so if it is not too much trouble to make some kind of short demo showing how this phaser works

.......so that is all ......hope I did not chased you away with my demands

if you do not have time, it is understanable

thanks again

cheers

i have one of these and i really like it but for one or two things, the rise and fall are equal and there is a little stutter or garble at the point where it turns over. also the bypass switch can be a pain to hit without changing the speed especially if you've been drinking. other than that it's great. it can be a subtle or strong as you want. i redid my whole pedal board just for this pedal.

if anyone has any suggestions on how to smooth out the lfo i'm all ears...thanks.

Hi, I owned one of these and just love it! the strange lfo shape around turning points is probably due to the fact that the light that sets the lfo speed is also used to show the LFO from the outside... so the actual lfo shape is not a simple triangle or whatever, but a function of 2 LFOs... a way to change it would be using a separate light source for the pedal-blinded light... which shouldn't be that difficoult....

anyway, best phaser ever! I am trying to squeeze one in a BB box

Too late because ianZeds already posted a good one, but I received a lot of schematics (paper, not scanned yet) a few weeks ago, including those for the chrome Morley pedals.

Most of them are already on the Morley site (to which I link), but maybe I have to check the quality of those...
