Relative Two Key Tremolo tuning

Ok, here's a neat little tremolo. Don sent me an echo for repair quite a while back, I'm going to have
to actually make reeds for it, I'm not going to have time to make any reeds until next month at least.
So, in the meantime, Don has been very gracious about it. Also in the meantime, I've been cooking
up a neat little Tremolo for Don as a thank you for being so cool about everything. I'm pretty sure
it's a one-of-a-kind. It's a three key Bergzauber. It has a new tuning I came up with, two key tremolo,
then a regular C solo tuned on the other side.

The C side has the regular tuning. The G side has a new tuning, I'll call it the two-key-tremolo tuning.
It will work on any solo-tuned tremolo tuning.
Here's the new tuning on the G side vis a vis the old
Old:
A C E F#A C E F#A C E F#
G B D G G B D G G B D G

New tuning:
A D F# F#A C E F#A C E F#
G B E G G B D G G B D G

The point of this is to make Em playing more natural. We're taking what was essentially a draw
harp position for Em into a more powerful blow position and the great part about it is both Em
and G feel perfectly natural. If you trace an Em scale on the original and then on the new tuning,
it should make it clear.
I embossed the reeds and did some gap work. I also flattened the comb, I sanded the comb...
I thought, "hey, what if I made a tremolo that was thinner? It would probably be easier to play
right?

I learned the hard way, that when you sand a tremolo comb that thin, the coverplates don't
fit anymore. So I had to drill it out and put some brass screws on it to make it work.

I'm not quite happy with how the Em G side plays, still doing some reedwork on that side. The C
side is perfect.
