DEMO Mantle Fuzz (Blue Box) with Mods

[DGWVI]

Built stock, except for a hardwired and maxed out MicroAmp at the output, and a toggle to select 1 octave down, or the classic 2 octaves down

Hold on everyone, here they come!

How does the toggle work?

Very cool that you modded this. I built the Fuzzdog version with a switch for 1/2 octave and I much prefer the 1 octave. @KR Sound you could reference the Fuzzdog build docs, but would also be cool if dgwvi shared the direct ppedalpcb board mods

Selected between pin 1 and pin 3 of the 4013

Yep. Well, I used pin 13. But so long as the connection to pin 1 is severed and you use either of those pins, you get the One octave down.

Super simple. Hardest bit is tacking the flying lead to the IC leg and not snapping either one
Or in my case with the sockets, not oversaturating the leg with solder

Lift the leg of R20 (1M) attached to pin 1 of the 4013 (the bottom hole) and solder that lifted lead to a wire.
This wire gets soldered to the middle lug on an SPDT ON/ON

Solder two more wire to the outside lugs of the switch. One will go to the now empty hole at R20 (-2), the other will go to either pin 13 or 3 of the 4013 (-1)

I maxed out the MicroAmp at the output.

Can you please elaborate on how you maxed out the MicroAmp at the output? Mine sounds like the stock demos, but I'd still like the output to be louder.

I built the FuzzDog MicroAmp stock, except instead of the Volume pot, I jumpered lugs 1&3

Thank you!

Hey there!
I've done the build with this mod but it not working correctly when the switch is to the -2 octave. Maybe I understood the mod incorrectly.
Could you look at what I've done and tell me if everything is supposed to be ok?
Thanks in advance man!

Pin 13 should still be in the socket

 

[yo571x]

Yep that's what I figured by analysing it but wanted to be sure by asking ! Thanks a lot for the answer!

nice! how you doing them cool stamps for labeling?

Rubber stamps- either Pegz brand (typewriter) or a custom set (peignot)

Stazon opaque is the ink I use most frequently
