Is this the final layout for Analogman's King of Tone? Any build reports? Is the PCB transfer layout already made 1 is to 1 ratio?
There are numerous build reports and comments in the thread. please search.
to find if the layout is scaled properly, print it and place an 8 pin dip socket over the holes the opamp should go in, if it lines up, cool, if not, adjust as necessary until it does.
and just for clarity's sake, you should know that this particular layout is half of the king of tone, as the king of tone actually has two of these cascaded. we just didn't see the point.
but I can still use this as a whole for DIY analogman KOT right?

The only difference between the two is that all the pads for the pots are lined up on the top, and it doesn't require any jumpers. There's no difference, circuit-wise.

Yes, the KOT is two identical circuits in one box. Just build two of this circuit, put them in one box and wire the 3PDT output of the first circuit to the 3PDT input of the second one,that's it. You can build just one but I like having both so I can set it up as having either a pre or post boost.
It always bothered me that the drive control only seemed useful in the last 30% of its range (from about 2:00 to the max 5:00 position). Yesterday I changed the resistor in the first IC stage's feedback loop from 10k to 56k and changed the drive pot from 100k linear to 50k linear. This more or less takes the drive available from the last half of the stock 100k drive pot and spreads it across the entire range of the 50k pot.
With this 56k resistor and 50k pot arrangement it makes the drive knob less sensitive to tiny adjustments so it is easier to dial in the amount of drive. It now seems to go from a mildly overdriven boost with the drive pot at minimum to the same overdrive as the stock configuration with the drive pot wide open.
I thought others might find this little mod useful.

deaj's is not the king of tone. deaj's is just a bunch of mods he did to the original bluesbreaker circuit (which is what the king of tone is, with a few component changes). the madbean is the actual king of tone, deaj's is a different circuit.
I just opened up an old jvc bookshelf cassette/cd stereo and found a bunch of diodes that look identical to the ma856's I got from effectsconnection. Some are identical while some have a white stripe and others have a blue stripe.
If somebody has the time, could they post the schematic and layout for one side of the KOT?
Also, if you were modding one of the GGG Bluesbreakers, how would you go about adding a toggle to switch between the dip switches? Is that possible?
Sorry, I thought of another question after I finished posting, and I couldn't figure out how to edit. How do you guys go about switching out different components to try them out? Once I build this I'm hoping to go about trying out different chips and diodes, and I was wondering how you guys were able to experiment without building a whole new board?

If you don't want to swap components.. it's probably best to breadboard it.
For things like diodes, build a separate board that lets you switch in different types to try. you'll use it a lot if you like to fine tune your designs.

Here is the updated King of [K]lones board I alluded to some months ago. It is an improved layout with no jumpers. Have at it!
I do have a newer board that has the full KOT circuit with internal dip switches like the original. That is available through my PCB service. Of course, you can use the King of [K]lones board to do the full circuit...just put two in one box!
Print the PnP image at 600DPI for an exact match. The other two docs are 300DPI.
Sorry for all the questions, but does anyone know where I could find a breadboard this size https://img141.imageshack.us/my.php?ima ... erojs2.gif
Also, what are the red squares with the red circles in the middle?
Thanks for all the help guys, you've really made my first few days here a positive experience.
Pedalplayer, that layout is a strip board , not a bread board. The red dots are cuts in the strips. Hope that helps.
KindaFuzzy - Looks like a blue nail polish and nutella sandwich.

Guitarlcarl - I did take offence at being called an idiot by a moron.

Where these squares are the copper strip should be cut! The red dot is the existing hole at that spot! The simplest way to do this is with a drill bit using the hole as a center! Deep enough only to cut the copper strip at that point!

I just realized what was posted in this thread is the schematic for one side. Sorry guys, I got confused.
