Alas, the T-REX still has a side-mounted power jack.

FAIL.

So far, all that I've been able to find:
Fox Gear, all jacks up top.
Dr. Green Tune Up, all jacks up top!
Korg Pitchblack (also came in Red, Black and ?)
Older Original Peterson Strobostomp had top-jacks. One step forward...
WTFudgsicle~ Why did Peterson go with sidejacks on the latest big-screen tuner? Two steps to the side and wayyyy back...
Use to be you sent your EB Vol/Exp pedal off to an outfit such as SHNOBEL TONE to mod it with a tuner, but now EB offers tuners straight from the EB factory with top-jacks, of course.
From the
Polytune thread, Boss' TU-1000 is bigger than some stages I've played on, but at least it has top-mounts:
< A better size reference.
Then the Boss people tried to save space by omitting the stomper on the TU-3...
Yup, that sure saved a lot...
I'll be sure to stick one of these in my pre-amp's always-on tuner-out.
Tune'm Dano!
Danomatic Beige, also came in ...
PURPLE !
And
red and
blue...
This Morley Accu-Tuner should've been named Deja-VuTune, except I guess it's not a VU-style ...
