Thanks Greg;
Reyburn CyberTuner is all digital.  It uses a software digital filter to
get rid of everything but the one pitch for which it is single-mindedly
listening.

The point being that digital filters have a much higher rejection ratio
than analog filters.  RCT rejects noise in a similar way that digital
recording for Compact Disks rejects hiss and other noise in the recording
process.  In practice this bears out, and RCT works great under severe
conditions.  I sometimes tune for concerts where the conditions are, well,
less than optimum for aural tuning, and RCT comes through for me.  I've
never had a complaint on this, the RCT users just take if for granted
that it works fine under noisy conditions.

As RCT user Tom Cole pointed out, RCT's automagic noteswitcher doesn't
work as well if the noise is real bad or if the noise is close to the
note at which RCT is listening.  In any case RCT is compatible with the
Fairchild Accu-Pickup, a magnetic pickup available from Inventronics
or any SAT dealer for $75.  The magnetic pickup is stuck to the plate
near the sounding string.  This gives either the Sanderson Accu-Tuner or
Reyburn CyberTuner an even greater rejection of outside noise.

In practice I have never had to use the magnetic pickup in tuning since
RCT rejects noise quite well, I just use the pickup for experimenting.

Hope that helps!

Happy Holidays too all!
