Is it possible for you to post a schematic for this Boris?..... :)

Here's a schem for reference, although I haven't checked Boris' layout to see if the correspond exactly.

I have built madbean's deadringer. It was so good I sold my fulltone custom shop fulldrive 2 (the cream one, almost my last boutique pedal).
This is my favorite TS. The boost is a bonus!

boris i like your layout style. Curves are great.

I also like your enclosure. Is it etched?

....You are so kind....and yes it is etched :thumbsup

...thank you himister...so are you here to stey or you just dropped in by accident? :lol: ...knobs are supersecret :evil:

Boris' layout to see if the correspond exactly.
.......Thanks...I have checked....differences are (errors on my build)......

1...... resistor from base to V/2 of first transistor is 1M...should be 510k
2...... mosfet clipping section have no room for Ge diode( so cut trace and add it
3......most imprtant error is resistor 47K should not be connectedto pin 7 of the IC....so just pull it out from PCB and make wire connection to little SW

Where had you got the etching for the case done ? I've tried trophy places & engravers
but not much luck locally

Hi, folks. Does anyone have the correct schematic diagram of Fulldrive 2 mosfet pedal and you can send me on PM or e-mail?

Thanks a lot in advance!

:cheers

Hi!

I'm having terrible difficulties making the three way on-on-on switch work for the comp cut/fm/vintage settings...what is the correct switch for the job?

Thank You!

I used this one: http://au.element14.com/multicomp/1md6t ... /155018501
Check the datasheet on that page for the pin configuration for each switch position.

I built one from aionelectronics.com/diy-pcb-projects/ (see his TS board) and i think it sounds pretty damn close to what I heard in the store with a real FD. I LOVE it!

I've encountered multiple Fulldrive 2 MOSFET versions in the past. One even had a FET input transistor.

The schematics of these units:
2007 version:
Fulldrive 2 MOSFET SN02889.JPG
2009 version:
Fulldrive 2 MOSFET SN13685.JPG
2017 version:
Fulldrive 2 MOSFET SN49704.JPG
I've added pics on my blog about these three models
