Hi guys, did this
http://www.singlecoil.com/docs/tubescreamer.pdf
(p.6)
to my stock TS9 reissue; what an improvement!
I only swapped the resistors as the stock chip was the 4558D and it really opened up and is much more tasty as a boost than it used to be.
It s also nice and smooth when I crank the gain.
I m very happy and wish I had a SL to push though the badger ain't bad either.
My first mess about with a pedal and I m really impressed by what swapping 2 tiny resistors can do.
Wonder what the analogman silver mod is now and what it could do..
Any ideas?

When I tried different values for the output buffer in the Valvesporker prototypes I couldn't hear a difference between them. In the end I ditched the output buffer altogether.
Luckily there are many useful changes you can make to a TS circuit with a switch - but the 808/9 resistor swap is not one of them.
If you don't believe me or Beavis Audio, try it. You can use a single DPDT switch since you don't need to switch both ends of the two pairs of resistors. Best to leave the switch hanging and not drill the box just yet though .

Personally I can't hear the difference between the different chips.
My trusty old 80s TS 9 I got for 10 deutsch marks second hand in 88 has always been in my board. It even has the "worst" of the chips in it.
In the tubescreamer circuit, it makes very little difference and they switched the chip out for many others. The only one that sounded noticeably different was the last chip, which was a video chip!
They also said the "mojo" chips never went out of production in Japan, and that was a myth in the guitar world.

Something I've been working at recently is triangle testing (as it's called in the food industry). Essentially it's that if you're given two similar (but not identical) things to try, you'll very often be able to identify differences between them. However, given three similar (but not identical) things to try, two of which are the same, it's usually very difficult to identify which is the odd one out, even when you could identify differences between the two samples presented together.
With anything that relies on your senses and perception (sound, taste and more) testing fairly is quite tricky to do.
It is possible that the output resistor change *could* have some effect into something with an unusually sensitive input - although none of the other changes can, exactly because the buffer will prevent that. But, with a direct-switching test (which I think is the most accurate, even more so than recording), into a normal valve amp, there was simply no difference whatever. It wasn't even possible to tell the switch was being operated most of the time unless it caused a tiny click.
It's really not a difficult thing to test for yourself - if you can mod a pedal, you can try it.
