I have a ts808 clone (bbe green screamer) that I'm not completely overjoyed with. The chip inside is a tl072 and I was thinking about putting a socket in there and trying a few different ones.
1) Can I just substitute chips like NE5532, LF353N, and JRC4558 without performing any additional mods?
2) Could I use a NJM4560D (http://www.mouser.com/Search/ProductDetail.aspx?R=NJM4560Dvirtualkey51310000virtualkey513-NJM4560D) IC in it?
3) How about op-amps that are single-supply rail-to-rail? Can a chip like the OPA2340PA (http://www.mouser.com/Search/ProductDetail.aspx?R=OPA2340PAvirtualkey59500000virtualkey595-OPA2340PA) go in there?
4) I've also read about the TL2272, but I have yet to see it for sale anywhere. Anyone have a source for those?
5) Also, I have noticed there are different versions of some chips offering different "Rejection Ratio" and "Input Offset Voltage" values. For example, this is the result of a search for LM1458 (http://www.mouser.com/Search/Refine.aspx?Keyword=lm1458) on Mouser's site. How do I know which one to buy (for Neutrino)?

I don't know much about these, but I think so.

It's actually TLC2272 (http://www.mouser.com/Semiconductors/Amplifier-ICs/Op-Amps/_/N-4h00g?P=1z0z7v3&Keyword=tlc2272&FS=True)

Actually, when you reduce the search to only PDIP packages, you only get one result:

In general, the smaller the offset voltage, the better.
Thanks!
