3.6 – 7.2V was just what was stated on the schematic, that may have been under certain set up procedures, it’s moving which is the main thing
I misread your post, I thought you meant in filter matrix mode it would flange as you turned the rate pot so yes it’s possible the pot is the issue.
So you checked the switch for continuity? It may just be a loose solder joint, seems you’re going in the right direction though.
You can check while in flanger mode if you have moving voltage on Pin 5 of the 324, that would mean the LFO is reaching the range pot and if stops moving at pin 7, may well be the range pot.
Given the Digitech Whammy & The Drop and the EHX Slammi and that there’s no indicator display on it, I think my guess is close and it’s not a tuner
The knob is a rotary, can see text around the outside and while it’s tricky to tell I think the second knob is labelled blend (something the Digitech Drop was definitely missing).
Possibly a ring modulator or harmonizer though.
…but someone should definitely make a Wurzels signature pedal.

First thing to do, plug it in, power up and take voltage readings on every chip (black lead to a ground point such as the enclosure, set on the 20V range and use the red lead to probe) you measure the pins in this order with the tab, notch or dot indicating the top of the chip (if the chip has a notch and a dot, go by the notch) http://www.remotefactory.com/images/8-pin-dip.png post them up and i’ll check them.Awesome! I will check them today. I really appreciate the help it’s vey kind of you. We had a faulty dryer go south on us yesterday with a gas leak otherwise I would have already got the readings.
Sorry to hear about that, hope you get it sorted soon!
Just remembered that the DMM is actually positive ground so put the red lead to ground and probe with the black one, sorry about that.

The numbers under the chip are the batch code, you can ignore them.There is no reason for the delay chip(s) to be dead, in fact they rarely die at all it usually one of the other parts that has gone, people wrongly assume it’s the BBD as it’s the most expensive/rarest part.
A Memory Man is a large pedal to debug if you have no prior experience, it could be many problems, you can send it to a tech or get a multimeter and the schematic if you’re determined to fix it your self, certainly can be done but you’ll have to put the work in.
Ah okay thanks for the good info! I have a multimeter and am In no rush so I will see what I can find.
Great!
