Possbile Thor build

[Don]

Hi...farely new to the boards but have built some of the diy projects here ( sparkleboost, fatbastard, ea tremolo ) lot of thanks to all you guys esp. markm....
anyway, I am planning on doing the ROG Thor pedal and was wondering if the use of carbon comp resistors and high end capacitors (sprague, sozos ) would be beneficial at all? And where would I be using these parts (based on the schematic and BOM on the ROG site....thanks in advance.......

Welcome (sort of, since you've been around for a while )

Here's an excellent article by R.G. Keen on the use of carbon composition resistors:
http://geofex.com/Article_Folders/carbon_comp/carboncomp.htm

The whole site is a fantastic resource, and it's on the "required reading list" here: http://geofex.com

Good luck!

THe difference you hear will be more noise with the CC resistors.
I would very much doubt you will here a difference with the SOZO caps vs Poly film caps. Of course the board will be much larger with the SOZO caps...

Here's my Thor build:



I used some "amp caps" and some CC's.
Of course i couldn't A/B with other parts, but all i know is that my Thor sounds fantastic
and it never left my rig since the day i built it!

I mostly used metal film resistors, especially in the input stages. The CC's went to the "speaker emulation" filter.

I doubt if they improved the sound, but maybe they added a little something (...noise).

The large "amp caps" are probably an overkill, too. At least in such dirt boxes, according to some.
I always use such caps. I found many times that they sound "better" to my ears.

It's DIY after all... Do whatever pleases your soul!...

Thanks for the replies...i have been sidetracked on this project but will still build it in the very near future...in the meantime, i built the noisy cricket mini amp (thanks to beavis audio)......
