Regular Titebond. TBII (or TBIII) has more resin, might lock up
before you get the joint driven all the way home. Music
equipment gets babied, so you won't need the extra strength
or water resistance of exterior grade yellow glues. Sliding
dovetails are tremendously strong anyway, by virtue of
glue area.

Extending the back panel maybe 3/4" below the ledge will
add strength against the back panel breaking at the joint.
You've considered that, seeing how you've placed the dovetail
high.

Do you need full 3/4" lumber? 1/2" or 5/8" might be
sufficient, and will weigh less.
