Yes. This is fascinating. When I see that even a reputable guitar with
an adjustable tailpiece routinely has +-3 cent intonation errors, I no
longer have any hesitation in saying that a Blackjack guitar _is_ a JI
guitar (forget quasi and wafso), and possibly the ultimate JI guitar
in regard purely to numbers of available JI intervals. But of course
there are many other properties one might want from a JI guitar.

John,

Many thanks for passing this info along. It so happens that I've been
checking out specs of the Peterson VS1 and 490 strobe tuners the last week
or so, have been about to buy something, so it's really useful to know about
this other possibility.

Has anybody used any of these particular tuners? I've recently been doing a
lot of work developing my ability to accurately play JI on my fretless
guitar by ear, and have been thinking that practicing scales and slow
improvs with a tuner on for checking accuracy couldn't be a bad thing to do.

I believe the Peterson tuner is the one that many piano tuners use,
but it's at least double in price from the tuner made in Ann Arbor,
MI, that John Starrett mentioned. (Aside: I love Ann Arbor...)

Personally, I tried to use the Korg 1200 multituner to tune a piano,
but the timbre is *so* different from the piano it became fruitless.

Well, I learned *one* thing... how difference in timbre and overtone
structure can COMPLETELY affect tuning. The timbre was so different
it was hard to tell if the pitch was even in the same octave (!!)

It was back to "counting the beats" for me, after *that* experience.

I note that Johnny Reinhard, with whom I "share" this particular
tuner, has also found it not particularly practical...

That Korg probably works best with guitar... Wim Hoogewerf uses and
enjoys his...

I use it on my guitars but I also tuned a Fender Rhodes electric piano
with it last Summer.

The Peterson 490 (one of the models that piano tuners use) lists from $750
and up with extra features, but discounted from Sam Ash comes out to around
$500 +, right in the same neighborhood as the tuner, PST-2, that John
Starrett mentioned. What might be of particular interest to folks on list is
that Peterson is now making a "virtual strobe" tuner, VS-1, it retails for
$329, street price $230. Less features than the others, but very portable,
and 8 factory presets including Just major in key of C and pythagorean...
I'm considering it, but the other units for more bucks have more features,
of course.

here's their link
