commas in equal temperaments

Paul...I've been playing 34 tone eq temp for a while now, and it is
known for it's comma. In fact, let's get that out of the way: there is
nothing "pseudo" about this comma, it's just using the term for an equal
tempered phenomenon rather than a pure tuning situation. As long as the
difference is made clear, comma will suffice.
Anyway, here's what happens in 34...first, if you take an E major
chord in 34, and then a G major, the B note will NOT be the same
note in both chords; they are different by 1 increment. This is a hoot,
and I don't agree with Morrison that this comma is either an error, or
something to be avoided; I am learning to embrace it, work with it...the
results are totally unique. It is a challenge, to be sure, but the vistas
are pretty exciting.
Next, there are 2 separate circles of 5ths in 34, as well as 2
different whole steps, one representing 10/9, and the other 9/8. The
major and minor 3rds are only about 2 cents from pure, the 5th is about 4
cents sharp, and the ratios 49/48, 25/24, 17/16, 13/12, 20/17, and many
others are mighty close to pure. People have called it the just intonated
equal temp for good reasons, and I think it is a good direction to
pursue. I am composing on both electric and acoustic guitars with 34;
there's a lot going on with this system. Feel free to post me privately
if you have other comments.
Also, there's a misunderstanding about Brian Carlson's post
concerning his guitars...one is 19 eq, and the other is 18 unequal; this
is the one that Rankin helped design. So, all you guys who were wondering
about the ratios, it's 18...Hstick

Rusty sounds interesting. How would you compare it to OpCode's Max?
