hey

so I am very new to this business, I have built some kits, but still am not great at reading schematics, particularly when things are wired with awkward ribbons, and I am also not familiar with the resistor color scheme used in this pedal.

I am trying to do some of the modifications posted here: http://rkerkhof.ruhosting.nl/Taas/Mods/Big%20Muff.htm

particularly the tone control modifications and adding the extra knob that Jack Orman suggests.

Could anyone be so kind as to look at this picture and circle the parts that correspond with the tone control circuit?

I see the picture with the diodes circled but not one with the capacitors or resistors?

You may wana check out my page too:http://sovtek.webs.com/
I havent added any mids control projects yet.

When I add projects I make them with actual photo's of the PCB's so biginers can do them easily.
I also post the schematics so more advanced DIYers can use them if they wish.

The site is brand new and i still have content to add so just keep in bookmarked as more will be added continually.
