Modding a rog Thor to make it less trebly?

[ozzu2000]

Hi,
I've built a rog Thor, (http://www.runoffgroove.com/thor.html) I like it a lot, but I find it to have too much treble. A partial solution is to turn on the bass boost, but then the mids are the ones lacking  
Is the any cap I can change inside in order to make it have less treble?
Maybe removing the 470p cap just before Q2? Increasing the 1n cap after Q1 to 100n?
Any ideas are welcome!

Try adding a 330k resistor between the 470p Bright cap and the switch lug.

Thanks for the reply 
I find it too trebly even with the bright switch turned off (just personal taste, I'm sure the pedal is perfect as it is).
But that is a very good solution to tame a bit the bright switch and make it more usable.

I've just replaced the 470p cap just before Q2, and the 1n cap after Q1, with 100n caps. It gets a much a thicker sound now!
I've also added the resistor on the treble switch as suggested by B Tremblay, in order to tame a bit the highs when this function is activated.

As I've said, I'm sure it worked perfectly as it was designed, I just changed it to suit my personal taste 

OH! Another thing, with this mod the pedal is now bass guitar friendly! 
It is a very versatile pedal, goes from light overdrive to near fuzz heavy distortion.

Glad to hear you're enjoying the circuit!

There's one more way: increase the 470p cap at the non-inverting input of U1, that'll cut the treble a bit.

I'll try that as the caps I changed seem to make the distortion less pleasant and more harsh

I reverted the circuit to it's original caps, and following hex_void suggestion jammed a 470pF cap between pins 3 and 4 of the IC as this doubles the value of the output treble bleed (I think).

Gain stages are left alone and no soldering required.
Easiest and most effective mod ever
