Unorthodox but seems to work very well

I just wanted to see what your thoughts on this are because it's one of those things that no one seems to do but it sounds great so far. This is a marshall style scratch build that sounds a lot like an idealized JCM 800, which was my goal. But i recently thought i wanted a bit more clarity in order to insure better cut in a mix so i stuck a 47k in place of the 33k slope. I didn't really notice extra clarity and a bit thinner tone like i usually do with a 47k there, but the tone overall was just richer and really much more adjustable via the tone stack controls where i could get a wider usable range.

This is where the unorthodox part comes in. I had the chassis out and played it like that for a couple days really digging it when i looked down at one point and realized it wasn't a 47k i put there but a 10k ! I was really surprise because i never used anything there below a 33k because that seemed to be the lowest i'd ever wanna go. But having accidentally used a 10k i was finding no extra loss of clarity or muddiness in the lows, plus a smoother better tone with the ability to get anything i could before and then some.

I believe I understand how the slope works, it simply changes the balance of how much signal the bass and mids get compared to the treble. So i'm assuming what happened that i'm liking is that by adjusting the controls to compensate i can still get the same tones, but the range of usable tones is more centered where i feel it should be. If that makes any sense. Funny how it also sounds smoother and richer tho even when adjusted to the amount of highs i normally use. Anyways, just wondering what you all think about this and why you think no one ever uses such a small slope resistor.

Some amps will put a 250kL pot on the faceplate called midshift which is really a variable slope resister.

Also, you can use a 120k trimmer pot on the board with the 10k limiter resistor so no lower then 10k but adjustable up to 140k total resistance.

Some of the Orange Thunderverb amps use a 22K slope off the plate, which is the lowest I've personally seen.

I keep trying the 33k again to get the A/B thing happening but i keep going back to the 10k. I'd like to see someone try this and report what they think. Doesn't make sense to me that it should work well since no one else does it. Maybe after a week or so i'll change my tune, who knows. Sure seems to work great tho.
