I love my Dobro, I play slide with alternate tunings, Usually G or E, it’s awesome. I have a hound-dog resonator it’s acoustic/electric.
I’m also a pro level bassist so I have a lot of guitars and stuff.
Back when dinosaurs roamed the Earth, and Jimmy Carter was President I started college as a classical guitar performance major.
I was run over by a drunk Democrat lawyer and have nerve damage in my left arm, and the head injuries messed up my ability to read and play music at the same time.
I haven’t really been able to play in over forty years.
Over the years I've acquired instruments based mostly on what bands I was in and what worked best (e.g. I got into a 60's cover band that did a lot of Byrds, Beatles, etc. and thus the Ric 12-string had to be). But never had occasion to need a Dobro, although I love the sound. My collection is full -- can't fit anything more on the wall, lol -- but I've always wanted a good excuse to get a Dobro. I'd likely tune open-E, that's what I do when I play slide.
Who knows, maybe before my fingers get arthritic (I'm 72 and so far so good) I'll find a band that needs a Dobro player and convince myself that I should start hanging things on the other wall. :-)
