I think it's a difference based on components tolerance only, but I might be wrong

MXR Timmy uses LF353 op amp. It is a higher output/gain op amp. Typically that results in some trade offs which might explain the minor differences.

Also, early units had some mods on the fly done which is always an iffy way to go. Gut shot shows resistor added in a unique fashion:IMG_0034.webpIMG_0035.webp
it also appears some additional components were added, there is a U3 at top left, an extra filter cap and some xstrs Q2 and Q5 at the bottom?

That 1KR soldered this way is one of the worst thing I've ever seen on a smd circuit, is it possible it is a DIY modified unit?
 
Finished the electrical build of the Axion fix Timmy yesterday. Have spent a few hours with it and it’s a good transparent overdrive but don’t like it as much as my old Paul C. Original. It’s a more aggressive boost, not as smooth and clean as I remember. Will keep on tweeking Axion vs original…IMG_3467.webpIMG_0037.webp
