Seppuku Fx/Jordan Fontaine Memory Lapse

 Another contribution by Jordan. Thanks mate!

I was playing with the Seppuku Fx Memory Loss that you had posted and made some adjustments for more versatility. The schematic we all have to work from is so sketchy I thought people might enjoy a thorough series of mods to it.

First off I added a Mix control. It could probably be done better and would love to hear suggestions. 

The C Taper for Stability gives easier adjustment over where the latch up occurs in playing dynamics. 

I set values at the Filter control. The on/off/on gives a clean delay, dirty repeats and very dirty repeats. If you placed a 1u in either C2 or C3 it creates a totally nuts fuzz.

I set components around the feedback and surge control to taste. 

The increased Time pot is for longer delay times, why wouldn't we want longer delay times?!

I 86'd the switch for the LM386/Pins 1 & 8. I'm not going to use it but it wouldn't be hard for someone to wire it in.

The layout is not verified. It is the result of fixing the board I built from my original layout. 

Hopefully no one minds a few diagonal caps. 

 

 

 

 

 

 

Seppuku Fx Memory Loss - alike

 The layout is based on a quite diffucult-to-read schematic found at Mod Wiggler forum.

It may contain some errors and there are few question marks next to some of the pots and one of the caps, so some "trial and error" might be necessary to get this thing working as it should. Also, the "Filter" switch looks like a feedback switch for the LM386 IC and it appears to be a panel mounted push button switch but I guess a SPST toggle switch can be used as well.

 Schematic is avaiable  HERE.

Seppuku Fx Mind Warp

Schematic, trace and info avaiable at FSB. Note that there is a cap value missing across pin 11 and 12 at the PT2399. There is a 10nF cap across pin 9 and 10 so a close value to that should work. Also, lug pot numberings isn't marked on iether of the schematics so lug numbering in the layout is just a best guess. Both red and green diffused LEDs has been used in the original circuit so a socket for would be a good idea as well as for the LDR.

*Edit 200809*

Dragao verified it using 820/8 LDR and green diffused LED. He also verified the Warp pot lug connections.
