Re: BAJA JVM overdrive pedal 040218 [verified]

You can use a 4PDT switch and separate the outputs.
This should fix it.

Re: BAJA AC30TB overdrive pedal project 110218

Hi Frank.
That was my idea. :thumbsup
Started a layout this morning but I don't have much time at the moment.
Wasn't sure if the tone would change much when switching.

Re: BAJA AC30TB overdrive pedal project 110218

I was thinking to draw a layout that switches between Normal and Top Boost.
It would have 2 Gain pots and 1 Tone pot that would switch just the cap from lug 2 (I think it's not possible to have 2 pots unless you omit the LEDs)
Would the Tone pot have the same response by switcing between the 2 modes?

Re: BAJA JVM overdrive pedal 040218 [verified]

Ok.
Pinout was correct. Just needed to be turned 180.
Can't edit any of the previous posts.

Re: BAJA JVM overdrive pedal 040218 [verified]

Here is a single toggle switch version (OD1/OD2/Crunch) that should fit in a 125B box.
Just in case.

Re: BAJA JVM overdrive pedal 040218 [verified]

Did you find a different pinout on Google?
You need an extra pole for the LED.
This is the version with two Level pots:

Re: BAJA JVM overdrive pedal 040218 [verified]

Not really but it should give the same results.
It always uses the same JFet buffer at the output (the way FausterCraster drawn it).
Adding an op-amp buffer instead shouldn't make any difference and just make the board larger.
The Crunch/ODs are still selectable.
I think it's correct but...

Re: Diezel VH4 Pedal [schematic]

Not sure about noise level (increasing the 47p may help) but my layout matches the schematic and it has already been verified by two different people.
Once again: what were those errors you were talking about?

Re: Diezel VH4 Pedal [schematic]

What are those mistakes?
I can't see any and the layout has been verified.
If there are, you should have the decency to mention them on the Tagboard blog so that they could be corrected instead of writing here that the layout is crap.
Looking forward to your better "uncongested" version.

Re: Guyatone's PS-021 Guitar Exciter [schematic]

Thank you for the schematic!
I want to draw a layout but I'm not sure about something:
to completely eliminate the flip flop switching from the schematic would you get rid of Q9, Q10, Q11, R15, R16, R20, R40, R41, R69 and C10?

HI! I've drawn a vero based on the schematic (http://tagboardeffects.blogspot.fr/2017/05/darkglass-microtubes-b3k.html#comment-form) and all of us there seem to have the same problem: general low gain and Gain pot not working properly when Grunt switch is in the middle position.

Re: Friedman BE-OD Pedal [traced]

Hi Pakrat! I know it's a lot of asking but would you be able to check a few things?
Does R2 (470K) go to VBias or the R32-R34 junction? C23 goes to Vdd or ground? Any chance of checking the whole scheme between R14 and Treble 3?

Thank you guys. I think Tagboardeffects wouldn't exist without this website. This is still the same layout based on Destro's schematic. As Bmxguitarsbmx said it may not be correct but considering Pakrat has already built it, it would just be a quick way to test those values changes. I've circled the...

Re: Friedman BE-OD Pedal [traced]

Thanks Pakrat for checking the values.
I think there are 2 slightly different schematics here: one from Bmxguitarsbmx and one from Destro.
I've used the second one for the vero layout but I'm not sure which one of the two was the right one.
