I noticed it said that an LM1458 worked better than TL0X2's but not as well 
as the LM442 - do you think different makes of the LM1458 might perform 
differently? I think of all the op-amps I have more LM1458's than any from 
several different manufacturer's and eras. I've found often that NEC 
versions of parts work superbly - like the uPC4072 as opposed to the 
TL072...

Anyhoo this looks cool. I've been WAITING for this one!
