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. 

S

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.

This on is verified and good to go.

Frost Giant Electronics Little Acid Fuzz

 

 Phew, loys of work lately so not much time for the blog and building lataely. A few people have sent me some new traces and new layouts. These will be uploaded today. First out is Little Acid Fuzz by Frost Giant Electronics.

Another Frost Giant PCB traced by Sergio. Based on the op amp version of the Little Big Muff from the late 70s. The internal Tone trimmer can easily be moved to the outside for a 2-knobber.

PedalPCB/Chuck D. Bones Yankee Screwdriver Deluxe Turbo

 Based on Skreddy Screwdriver but Mr Bones modified into quite something else...

PedalPCB / Chuck D. Bones Spunk-O-Matic

 How about a MOSFET/Germanium Harmonic Percolator with some extra controls? And silicon/infrared diode clipping? Chuck D. Bones Spunk-O-Matic has it all...

Aion Fx Traynor TS-50B Bass Preamp - ON HOLD

 Schematic is avaiable HERE.

 

 

Chris Stelloh managed to squeeze in the power module mentioned in the Aion build docs. Hopefully it will solve the issues with power and noise.

Death by Audio Black Card Fuzz Delay

 Once again, Ian Sheridan sent me another one of those DBA business card circuits to trace. 

 

 

Top Gear Treble Boost

 Schematic is avaiable HERE.

I added a "Boost" control at the end of the circuit since this thung is supposed to be quite loud.

Madbean BirdDog

 An old forgotten madbean project based on the pre amp section of solid state Squier 51 amplifier. I really find these SS amp designs interesting and they usually ditorts in an interesting way. The op amp types aren't specified in the schematic but I bet TL072 will work fine. You can also try op amps with bad specs like LM1458 or LM358, things might sound more fuzzy and dirty with these.

...and Ian also wanted to contribute with a layout....TCHULA!

Verified and good to go.

T-Rex Mudhouny + Green Ringer

 Jordan sent me a layout and of course it qualifies as an entry on the blog. Still unverfifed, though.

Demedash Effects Incandenza Relay Bypass

 Here is a contribution from Chris Stelloh that seem to be really useful.

Chris says:

This is an updated version of the Demedash Incandenza micro-controller free clickless relay true bypass switch. It takes up a bit more room than a simple 3pdt, but because of the friction-free operation of the SPST button, it will last WAY longer than that same traditional, mechanical 3pdt switch. I realize that most folks will not want to build an extra board where just a footswitch will do... but for those of us that DO, here's my drawing of a super-slick, silent, clickless relay that doesn't require any coding or microcontrollers. There are a few earlier versions of this circuit floating around the web, but this one has a very important update from Steve Demedash himself. The power filtering and 100 ohm resistor between the 555 and the relay is super important. I found that the power spike when engaging the flip flop was enough to mess with other circuitry that was close to the switch. For example: I had a dual circuit build with independent on/off switches and triggering one would sometimes trigger the other one unintentionally.

Anyway - here's a boring utility layout that has ended up being the thing I build the most, since I put these in just about any circuit that will permit it. This layout also allows you to omit the polarity protection diode for the main board and the status LED as well since those are both contained here on this switch daughterboard. The 5v DPDT relays you can use for this are not limited to just these three - however, these three are the smallest and most inexpensive I've found so far. Also - I don't like to use standing axial components or 3-row resistors but in the case of this board, I wanted to keep it as small as possible. Be sure and notice the anode of D3 connected to ground!
