Modding a Dunlop 535Q Wah, how different is it from the Dimebag Wah?

[navin]

Guys. I started a topic on modding a Dimebag Wah but my plans just changed. The thread I originally started  for the Dimebag Wah Mod is here.
http://www.diystompboxes.com/smfforum/index.php?topic=113286.0

A friend of mine called to say that he has a 535Q that he does not use and is willing to give to me for free. I don't know how to edit the title of the old thread to switch to the 535Q so I started a new one for the 535Q. Sorry if it causes any trouble.

The way I see it, Dunlop has made some significant mods to the 535Q to convert it to a Dimbag Wah. Does anyone know what all of these changes are? I can see some LEDs near the heel, an extra fine tune pot and an extra output. Besides the basic tone of the Dimebag is far nicer than the 535Q, what has Dunlop done to the 535Q? Anyone?

These are the changes I hope to make:
1. Change the DPDT switch to a 3PDT switch and use the 3rd pole to turn on LEDs. This is documented here. I hope to install a DUAL colour (red-blue) LED in the top left corner.

2. Use the battery compartment to accommodate a Yellow Fasel, Red Fasel, and a Halo (tubesandmore.com has these in stock) and add a 3 way 2 pole rotary switch to switch the inductors and a RGB LED indicator in the top right corner. This has been discussed in the link below but I don't think it was ever implemented. I need some help: for example is there enough room to stick a rotary switch next the the existing 6 way rotary?

3. Change the caps on the 6 way rotary to provide for a wider range. Does anyone know what are the existing stock cap values on the 6 way rotary of the 535Q?

Thanks in advance. Any links, pictures, tutorials, etc would be helpful.

For the. Second rotary switch (switching inductors) will a 2 pole 6 way rotary switch do?

First pole switches between L1, L2, L3, L1+L2, L2+L3, and L1+L3 and the second pole switches a Red, Yellow, Green (RGY) to make Red, Yellow, Green, Orange, etc ? Where can one get a Red, Yellow, Green LED as shown below?

I wonder why GGG used a 3 pole 3 way switch instead of a 1 pole 4 way switch here. Any ideas.

For the switch, why don't you draw up the diagram and we'll let ya know if you're on the right track!

Thanks, I am on a mobile right now. Once I get to a PC I will sketch what I am thinking to do with the inductor switching. Thanks for the offer, that's all I need. A sanity check.

For the LED indicator is the information on the Gearpage link I posted earlier correct? See post #14 on that link. Thanks again.

If a 2 pole 6 way switch will work, where on the 535Q is there room to add a 2 pole 6 way switch? Will this brake-before-make switch do? Or is a make-before-break preferred for this application?

Why did GGG use a 3 pole / 3 way switch to switch between only 3 options (L1, L2, L1+L2)?  Would not a 1 pole 3 way switch have been adequate?

Change the caps on the existing 6 way rotary switch to provide for a wider range and add a 5M (pop reducing) resistor in the switch. Can this be done on the 535Q?


original schematic without caps


new schematic will look something like this

Add a 10k "fine tune" pot in series with the WAH pot (similar to the 5K resistor added to DimeBag's Wah) .
