Now that you have it apart and a schematic what do you think about the parts quality?
Is it as good as eternity and such?

I have read so many great review about the tl 072 but I dont think it sounds that good in this pedal. A friend of mine bought the green screamer the same time I bought mine and I socketed the chip so I can switch them out in real time and we hooked his stock version up with mine on the same settings before the mods and both the JRC and TI 4558's sounded much better to both of us. Surprisingly, The JRC4558DD even sounded better than the TL072 iin that pedal but to my ears, the TI4558RC is the best. I tried 5532's and even the Burr Brown 4558 and they all sounded good to me with the original chip being in last place.
