I've got a Danelectro 30" scale baritone that I bought off a guy on Craigslist for $300 about 10 years ago, it completely rules. I swapped the stock bridge for a replacement, because the old one was sagging in the middle.
The original design of this bridge, from the early 2000s Korean production run, has the overall height set by the outer 2 screws, which the front of the bridge sits on top of. String tension causes the pot metal baseplate to sag under the 4th & 3rd strings. So I got a CJ Tooling bridge:
The new bridge certainly looks better, and is much easier to adjust, but didn't change the sound of the instrument anywhere near as much as I was expecting. Which was totally fine with me, it sounds fantastic. (If you just have to upgrade something, upgrade the tuning machines. The stock ones were pretty stiff, now I've got some smooth locking D'Addarios that snip off the extra string length, too)
If I needed "A classic baritone sound" I wouldn't hesitate to pony up for the current production Dano:
But I would suggest tuning it ADGCEA (perfect 5th lower than std guitar) rather than the "B standard" tuning many baritone players use (BEADF#B) since these Danelectros are 29.75" scale and the D'Addario .014 - .068 & LaBella .014 - .070 sets work out nicely, tension-wise.
