Apologies about the delay, had a long weekend or recording (which I really would've liked to use this on!)

I've now permanently connected the fuzz and volume pots, and tested the DMM directly on a set of batteries. They seem to read fine (between 8.5 and 9.4).

I've also soldered in the transistor sockets to try to stabilise the readings, and also the input but only to the battery snap and GND) Still no joy.

I want to ask a question in case I've been really stupid - to set the bias, I place a probe in the test hole and the other against the GND hole?

EDIT: The readings I took the other day on the Transistors, are those ok?

Thanks! So, here's my readings (did some other tests too). I'm really not sure what I'm looking for, so hope these help. I've tried to be as detailed as possible:

Q1

emitter - Starts ~-0.60, then slowly drops off to 0
base - Starts ~0.60, then slowly drops off to 0
collector - Fluctuates between 6.00 and 7.00 then settles at 6.20

Q2

emitter - Starts at ~-1.00 then slowly drops off to 0
base - Starts ~0.60, then slowly drops off to 0
collector -Starts ~7 then settles at 4.88

9v in at board - ~5.25
Ground in at board - fluctuates then settles at -0.02

Attached are two photos, one of each side of the board. I've disconnected the pots.

So, I have done a bit more research, and I hope these readings are correct. I basically did a diode test on the transistor at Q1.

base/emitter .713
base/collector .709

Is that the correct way to measure voltage? Wow, I have got myself into a whole world of pain, yet I have learnt so much in just a week!

According to the interwebz, the pinout is correct - with the emitter being closest to the little notch (in Q1, this is going to ground, I believe). So the transistor casing matches the board print.

Ahem, how do I check the voltage of the transistors? The internet talks of resistance measurements, etc. but I'm not sure if these are the same thing.

Thank you!

EDIT: as I'm a total noob, I should ask this - would wiring the input and output jacks and/or switch lower the voltage in any way?

Good evening everyone! So, I've decided to be ultra-cool and build some pedals, of course without any knowledge on electronics. "Oh, it'll be easy" I thought.

Anyway, I've built two boards, both not working properly. I shall ignore the first one and concentrate my question on the second one, the Mangler. I am building a silicon NPN-based Mangler. I have followed the schematic/layout religiously, and have swapped the diode and electrolytic capacitors round to suit the NPN transistors.

The problem lies in the biasing. According to the schematics, I should be biasing the transistors to -4.5v (or something like that). However, I'm getting no lower than ~7.41, depending on what transistors I have in (I have 5 BC108s and 5 BC109s, and have tried various combos). Is this voltage reading due to the high hFE of the silicon transistors? And if so, how do I go about lowering said reading?

I haven't tested to see if it sounds ok yet, as I wanted to take this board slowly after totally ruining the other one (which, however, may end up working if I can nail this transistor problem!).

Thank you so much for your help in advance.
