Almost identical. I'd not seen that before, but I recognise user earthscum from DIYSB, seen to recall he posted a number of cool but fairly simple designs. I wonder if the higher collector-resistor and mix pot values might help reduce the volume dip in the middle? I played with the design recently ...

Some similarities to this design:

FWIW, you can try different transistors, clipping diodes and input/output caps on the Lofo.

Just finished this circuit this morning using the layout provided and it works perfectly.
Thanks for sharing!

I finally got my Black Toast built. Thanks for sharing with us bajaman!
I found I had to go even lower than 3.3k for the drain resistor on the booster section. A trim pot is a good idea here as mentioned.
I've only finished it a few hours ago, but like what I hear on both guitar and bass.

Populated PCBs One MayheM! PCB Project info: http://aronnelson.com/gallery/main.php/v/ANY-machines/MayheM_/mayhem_layout_001.jpg.html This is a wild noise-maker circuit. I'm including an LMC567 chip with each. Off-board parts and the op-amp are not included. $12 shipped in the US https://img.photobu...

In regards to jazzercountry and others that want to use toggles instead of rotaries. It seems you can use an on/off/on SPDT for SW1, the bandwidth switch.

I'm wondering if you can use a 3PDT toggle for SW2, the sweep control. Can anyone verify if it will work? It seems it would work. Thanks!

I think Davies Molding makes them. Part # 2310

I just built the Thing Modulator on breadboard today. The 100k resistor/100uf cap combo seemed to work fine. Very little background noise when bypassed. I used an LM C 567. Have you seen this?: http://experimentalistsanonymous.com/board/index.php?topic=1809.0 Another thing you could try is grounding...

If you're going to Triode, drive a little further north to the Jefferson Park area and stop into American Science and Surplus. They mostly have odds and ends, some pots, switches and resistors. However, I dare you to have a bad time at that store.

3/22 update:
All of the drive/fuzz boards are still available. Make me an offer. Thanks!

Rebote and Echo Base PCBs are paid for/promised.
The other boards are still available. Send me a message before Monday night (March 1) as I plan to go the post office Tuesday morning.
Thanks!

Got a PM on the Rebote board, but the others are still available. I can't trade for another PCB right now. I need to get the projects I have started finished as my family is expecting our first child in 2 months. :D I can do about $11 for the unpopulated PCB and $16 for the populated one. Send me a ...

Got my board today. Thanks!

Bought a set of 160 ultra bright LEDs from seller advancedelectronics. They arrived at my door, in the US, in about 10 days. The listing advertised UV LEDs as a part the set. When they arrived, the bag they're in was marked "purple". I thought there was a difference. So I tested them on so...

Looking to trade my:
Rebote version 2 pcb. It's a pcb from tonepad
Boss DC-2 pcb layout from topopiccione

For:
Phase 45 pcb - general guitar gadgets layout preferred
Dynacomp pcb - tonepad layout preferred
Maestro MP-1 phaser pcb

Thanks!

Sorry to dig this up again, but I’ve found myself in a situation where I need to move quickly and need to lighten the load. No reasonable offer refused!
