I just picked up the Hardwire HT6.
Pretty cool pedal.
Poly mode seems designed to get you into acceptable tuning range quickly.
Where as single mode (either chromatic or strobe) is designed for fine tuning.
I like that the HT6 is designed to look more like a fretboard tab (for lack of a better description).
Low E on bottom
High E at the top.
You pluck a low E, the virtual low E string lights up.
Either showing sharp, flat or in tune in chromatic.
Or strobing to the right if sharp, to the left if flat.(in strobe mode)
Poly mode seems strictly chromatic. So, no you can't get 6 strobes going at once.
For live use, I think the poly mode will work great.
In the studio, I think it'll work better in single mode, either chromatic or strobe for that fine tuning.
It is true bypass.
So, one won't having to worry about their signal being altered when recording in the studio.
And I won't have to put my rig in mute or bypass, unplug, plug into my TU15, tune, unplug, plug back into my rig anymore.
Looks great i shall take a look at it further as i am in the market for a tuner.
how does it handle lower tunings?
i've found some tuners have trouble tracking when you get down to C or lower
