Open Discussion / Friedman Dirty Shirley on vero
November 01, 2017, 09:37:58 AM
This has now been verified: http://tagboardeffects.blogspot.fr/2017/10/friedman-dirty-shirley.html

I want to draw a layout for the Guyatone PS-021.
There's now a schematic available here: https://aionelectronics.com/schem/guyatone_ps-021.png
I'm a bit confused by the flip flop switching system and I'm not 100% sure which components you'll need to eliminate to completely get rid of it.
I was thinking: Q9, Q10, Q11, R15, R16, R20, R41, R69 and C10.
Any help would be appreciated. ;)

Chris has checked his original pedal and posted the corrections on https://tagboardeffects.blogspot.fr/2016/02/madbean-gravity-wave-earthquaker.html
The only difference between Brian's schematic and the original is C9 (not 330n but 3n3).
R9 should be 1K.

There's a writing mistake in you IC3 voltages.
14 pins and Pin 11 should be 0.

Hi Cody.
Is your Dimension pot working properly?
Some people built it on vero and had some problems:

Thank you for your reply.
That sounds great!
It was already a great pedal and now will be even better !!!
If possible, I will have to find a way to add a Tap-Tempo switch to it (God help me!) and it will be perfect!

I know I shouldn't ask but I cannot wait: any chance to know the main differeces in the ZPSDX2?
Did you redesign the board or there will be anything new added?

Great project as usual!
Do you think this forumvibe mod would work? (C6=C7, C8=C10, C11=C14, C14=C17)
Could it be useful?

Hi Brian,

I didn't box it yet.
I didn't receive a 1M Rev for the Rate pot and I've tried a C500K with 2 jumpers without soldering it.
I've realized that when the Input wire is closed to those jumpers the noise occurs.
As soon as I move them away it stops.
Should it be ok once I solder the proper pot?
About the Tails, instead of the Valvewizard's mod is there a way to add a switch like the Echo Base using the Bypass footswitch instead of having to add an extra one?

Thanks

Hi!
I've built the circuit and I hear a very faint but constant clicking even when the mod switch is off. I didn't receive a 1uF MLCC yet and I've added a film cap instead. Could that be the reason?
Thanks

Hi!

I don't know if it's just me but I can't open the new projects PDFs.
Their names are not underlined like the others and when you click on them nothing happens.

Any particular reason?

Is "http://www.madbeanpedals.com/projects/index.html" still the correct address?


Thanks
