R1? or across the outputs?

It's a load. It goes at the output.

This does not do anything disproportionate.
Harshness is not on this page.
An epic length list of what it won't do is entirely appropriate for a buffer; and, this circuit is a lovely and helpful buffer. It is rather good at refusing to do anything else, so you won't be getting any harshness here.

That looks like English, but I still need an interpretation to understand it... sorry.

I built it wanting a bass boost.
Wasn't entirely disappointed.
It boosted everything's resolution.
Well, everything was slightly clearer.
Why else have a buffer anyway?
Slight problem is that it didn't boost the bass disproportionately.
Oops!
I should have asked for a bass booster.
I didn't get it.
Also,
If you wanted more harshness, you're not going to get that.
This may be a great buffer but it absolutely sucks at signal modification capacity.

Can re-try with the southern version if you're sure. Wouldn't want to try that on the first go, so if that's the thing to do, then just mention it.

Um no...

I'm reporting I don't have any harshness because Keantoken noted higher voltage can come across with a harsher sound. I'm only at 12.5v.

And if you have a lack of bass maybe you're looking in the wrong place. It's an error correction buffer. So ya, I doubt it tolerates silly attempts to change the signal.

Hi Dan, tell me if you want a pair of Kuartlotron boards. I still feel a bit guilty about your disappointment with the Kuartlotron, with it not being a bass enhancer and all... But I swear, that one time it really did!

Will it make sense to use a silver mica cap for the input snubber?

Any 15pF capacitor will work. The general guidelines apply here. With a high source impedance a very bad capacitor could cause distortion.
