Mantle Fuzz - No output when engaged

[nichgriff]

Hello friends!

I have no output when the mantle fuzz is engaged. I'm very new to this and not entirely surprised - but thought I'd post to see if anyone had any thoughts!

I'm terrible at soldering and am working on it. I was really impatient and did not use sockets for the 4013 so maybe I fried that? But would that cause no sound at all? I also used an 1/8th resistor for one of them since I ran out of 1/4 but didn't think that would cause something like this?

Thanks!

EDIT: Works in bypass.

Always a good feeling when it fires up

It is a good feeling when it comes to life!!!!
As far as a difference between the TL072 and the 4558, not much. If you like the sound of the 072 the go for it. Audibly, its hard to tell which is which. I have experimented with them on breadboards and the 4558 is a more robust device. I had the circuit connected wrong and it didn't sound good, switched out a 4558 for a 072, and fried the 072. I put the 4558 back in and started troubleshooting further and found the misplaced component creating the issue. So that's my opinion based on personal experience, it's also why I have quite a few 4558's in the parts bin and only a couple 072's.
