Interpretation Q about the Guytone FL3 schem.

ok, great, keep up the good work then.
we will patiently wait for your layout.

Hi
The Eagel has landed, Huston we have Flanging
And it sounds just grate. No LFO ticking or any thing. I tested VR3 and R5 with a variable pot to find the spot where feedback is optimal. In my case 106K
The only thing I'm can think of is to increase the MAX speed, I will try with a 680uF but I did not have one in stock so I have to buy one and test. I have also updated the documents in the links to the PDF documents above. The silk and BOM is now inside the layout but I could not delete those links above. Use the PCB and the layout.

Here is the look


And here is the sound
Depth 100% Rate 50%

Max everything regen and a bit feedback

I remade my layout from the ground and managed to get everything in to one board. I also did some mods suggested above.

Removed the FET bypass and its components added a true bypass
R05=4K7
R5+VR3~100K (keeps some range for feedback increase to 150K if not wanted)
Decreased C19 to 10uF
Omitted C01
Changed the Resonance switch for a 100KA pot
Omitted R29
Possible mod is to use a 680uF for C02 to get a faster Max rate

wow, great flanging there solderman!!! 
also you did amazing work and fit all of that in one 1590A?! (I still can't understand how you do it?)

this project became first on my to-do list!

Sounds good Solderman!

I got my perf layout working yesterday as well. I will post my layout and schematic once I have a chance to draw them up in DIYLC. (I drew it by hand, and it is too messy to post...) There aren't many DIY able flangers out there, so I want to make sure we have this one out there for the people!

Hi Doc
That's a good thought. I specially like the FL3 since it's based on the MN3207 and not the more pricy MN3007. A 3007 is € 8,57 ($12) and a MN3207 €2,68 ($3,85) at www.banzaimusic.com where I buy them. You might argue that it's cheaper in the US but don't forget the customs to Europe.

I have sort of hooked on flangers at the moment. I happen to have two MN3007 in stock so I thought I would give the John Hollis Ultra flanger a chance. I made a layout and it fits in a 1590A as well. It's built around the MN3007 CD40406. I'll publish the layout etc as soon as it's verified.

The reason I first looked at this circuit was because I bought (5) MN3207/3102 chips for US $16.88. Super cheap!!!! Like me.

He still has a bunch, so if people want to build this, they should jump.

Hi
That is cheap. I might get me some and build this one as well
