Build Report Update wrote:L'Overdrive de la Révolution Deux: Photo Essay[/b]

Here is a short photo essay detailing the build of my very own LORD pedal. Tuck in, read and enjoy! Any questions? Fire away.

***DISCLAIMER***
The LORD is not a subtle sounding pedal when at full gain. Windows will rattle, ears will sear and any neighbors/front row audience will lose any fillings they posess. At lower gains the LORD can be used to get subtle breakup or just to boost your signal - the choice is yours the LORD is your tool.

1) The Schematic[/b]


First is the updated scheme. In my build I used a 100n cap on the source of the first fet and I used the "alt tonestack". I also added a "voice" switch which adds in a 4.7n cap across the 4.7n output cap I used for the mosfet stage (instead of the 10n stated), it essentially changes the bass response of the circuit from stock to what I call "thin".

You may want to tweak the caps about a bit to suit your gear. Alter the high frequency roll off points at the two Jfet stage e.t.c, experiment - play until it sounds how you like it!


2) The Breadboard[/b]


Here's the little sucker on the breadboard, testing was completed and confirmed that the little bugger made one hell of a racket - mission accomplished! (Note the cigarette burns on the carpet! Ooops!)


3) The Enclosure[/b]


I decided that "L'Overdrive de la Revolution Deux" needed a special enclosure (Read as; I was skint and didn't want to spend any cash buying a new hammond case!) I took the case from an old bust Ibanez phaser and modified it to my tastes.


4) The Enclosure Continued[/b]


A quick picture of the innards in place, you can see the squeeze I got into, having to slot that 3PDT in there was almost an error. The original footswitch will be used as a little "bonus feature" Note the tone bypass switch and the voice switch (which is lying at the side of the enclosure!)


5) The Circuit[/b]


I decided, for the extra mojo, to build the circuit point-to-point on perfboard. Here it is, layout completed and ready for the wires to go on! Note the two trim pots used for biasing the FET's to the correct voltage - very important!


6) Wiring and Test[/b]


After I wired all the controls in place I fired the circuit up for debugging, as usual there was no errors at all All of the wiring was kept as short and neat as I could be arsed with!


7) Installation[/b]


Next I had to install the circuit into the enclosure. Nice and neat . There is a prize for the first person who can tell me what I used the original footswitch for!? I was going to put a battery connector in there but I couldn't be bothered - I don't have any spare batteries, aparently we need those for the "Smoke Alarm".... Pfffft.


All Finished[/b]


Looking Good!



Still looking good.



Once more, just for luck!



So there it is, the finished article. One hell of an overdrive

Give it a try, you wont be dissapointed - "L'Overdrive de la Revolution Deux" is a crowd killer! Please, if you do build it, be sure to give feedback on how it sounds - what gear you are using it with etc....

I put a switch on the source cap of Q2 like Briggs did. If you don't want it put a jumper in there. Or turn the cap and put it directly in there.

The output is directly from lug 2 of the level pot.

PCB is exported at 500 dpi. When printed out it should measure 2,1" x 1,1".






Great thanks to Marshmellow and his work putting the layout together. One thing you should note is that in my build I used the "Alt Tonestack". It's pretty easy to modify the PCH layout to accomodate the alt tonestack... Both sound good..
