Looks correct as is.

Not all FETs are ideal for switching applications. I don't think there's anything wrong with how I've implemented it. Better to go the less convoluted route, anyways. As mentioned earlier, put a large value resistor (4.7M) in parallel with the switch to avoid popping.

As for being less bright, it's possible that the input and output capacitor values are not correct. I went with the values used in the Woodrow. Brightness is affected by the gain of the transistor used, as well.

here is my build

i used the last schematics version found here, except for the shottky diodes. I have put 2 in series to have same output volume whem switching between modes.
I really like the sound of it.

I'm not a builder, just a player... I recently bought a Les Lius. It sounds great, pretty much spot-on tone wise, but I don't understand why there's no gain control for the basic sound, just on the 'stack' channel.

For my taste there's just too much gain/distortion in the basic sound and I can't turn it down (only volume-wise).

Since you folks have dissected the pedal I was wondering if it this was some limitation of the circuit type, or just a design decision to please the power-chording bedroom-guitarists who must make up the bulk of the pedal buying market?

Any suggestions for similar sounding pedals around to try?

on proguitarshop.com videos there's a A - B test of this pedal againsta real Fender Deluxe, it my be only a woodrow but it sounds pretty close to the original, even better than I thought, interesting

absolutely, the sound is pretty much spot on. I was looking for a 'substitute' pedal for those gigs where I have to play through a borrowed amp (usually something like a silverface Twin...)

what wasn't obvious to me from the videos is that you can't turn the basic gain down - it's great for the zz top and neil young stuff, but if you want the sound of a Deluxe just starting to break up there's no way to get it...

i found "B" to be the pedal- you could hear the rattiness of the diode clippers breaking up, and the mid range just wasn't there. they matched up the tones better on the reveal vid better though... no surprise- they are out to sell pedals you know.

Anyone have a layout?

How the DPDT switch (S2) should be wired? I'm using it instead of spst because I want the led for boost switch also. I'm using the vero layout from the previous page.

So has anyone verified the layout/schematic have the correct input capacitors, etc.?

grabbed the la vache from madbean and used the schem (thanks madbean!) to make a 1590A layout.

it's squashed dowm so the toggles 'should' fit north of the board.. as yet unverified, but I've checked it a few times.. will be building in the next couple of weeks.. enjoy :block:

Another old layout I downloaded earlier this year. Didn't see it in this thread, so here it is.

I just build it using the layout of method but I don't get any sound, only in bypass! When I push on the stripboard near the 9v and ground points it works. Anyone able to help?

resolder the 9v and GND connections.

I did and the voltage reads normal on the 9V lane and 0 on the ground lane. Anything else I might have overlooked? When I push hard on the stripboard, I get a lot more sound coming out of the pedal!

i don't know what the pushing does. Maybe there is a microscopic trace shorting the tracks between those two. I recommend running a blade between then to clear the tracks. most problems with vero are because of that.

everything looks to be in the right place.

the other thing could be that the stranded wires unfiddled a bit when pushing them through the hole so there might be a tiny wire going from 9v to gnd, shorting it. try to look on the topside for this. Can be with any of the stranded wires when they are that close. I can't really tell from the photograph but it looks like there might be a tiny wire sticking out from the gnd wire.
