Hello. R.Wilson mixer

[Freq Band]

New guy here.

I just found this forum. I have been building some MFOS modules, most are working...some are not.

Anyways, this R.Wilson mixer schemo.....
http://www.musicfromouterspace.com/analogsynth/stereomixer.html
....is working. Two things though :

1) The headphone output is way too hot for my phones..55ohms and another pair 32 ohms. Where would I insert a pot (prefferably I'd use a resistor/attenuator switch (instead of a pot)).

2) I also tried opamps other than the TL084..these also work, and give lower background noise:OP471, OP400, AD713.
I hooked it up to a scope, and a square wave in, line-out does not produce a square wave out.....the trailing edges are sloping down a bit, and the headphone-out is some shape I am unable to describe (concave slope down, convex slope upwards??) Sounds ok though. Can I ever expect to see a perfect square wave out, on such a simple circuit ?
..or are my newbie measurement skills revealing themselves here

I'll post pics of this and other modules soon.

thx

I plan on building one of these mixers soon.....i will let you know what kind of behavior mine has.
