oh...That's absolutely genuine...I believe that one is particular is the "Mercury" line Bach cimbasso, whereas only seventy or eighty of the Stradivarius ones (all: in C, of course) were made.
The telltale sign that it's a Bach "Mercury" is the use of that Holton sousaphone neck in its - uh - construction.
Frank Holton and Vincent Bach were huge buddies, and they were always swapping parts back-and-forth...mostly on craigslist.
At the risk of triggering an owner of a (generic) one into a defensive position, I've never played one of the "marching baritone" cimbassos that I
- liked
- personally judged to have a trombone-family type of resonance.
A friend of mine (talented frankentuber), tore his "marching baritone cimbasso back apart, located an old/obsolete marching-something-or-other (ELONGATED LARGE TROMBONE-SHAPED BELL) instrument on eBay, RE-built his, and ended up with a successful instrument. (My friend's former marching-baritone version even featured epic response problems...which disappeared after redesign.)
repeated bragging, but 99% boasting on (not any "design insights", but) my LUCK:
I've never played any cimbasso (including any of the $2X,XXX ones) that plays anywhere as close to as well as mine (and no main slide trigger nor #1 slide trigger nor #5 slide necessary...It DOES feature a #2 slide trigger, as it's only a 5-valve instrument), which defines that it's going to be difficult for most any cimbasso to impress me.
Decades ago before I'd ever stuck any other instruments together, there was a three valve Holton BB340 that would be seen in a pawn shop every once in a while in Memphis. Apparently it had belonged to a student of Arnold Jacobs, and they would pawn it and redeem it over and over. One day it was actually for sale, and I think I paid $80 for it. It was the first instrument I ever cut to C. Before I cut it, it was probably the worst Holton B-flat I had ever played. It had the flattest F at the bottom of the staff and the sharpest F up in the staff of any of them. Believing at that time that something might possibly be able to be done, I've messed and messed around with it and nothing changed. I tried to do a more factory C type of cut than the guy in Wisconsin was doing (to avoid the "hole" at the bottom of the instrument), that didn't help anything. I also didn't have access to parts like we do today and had to use a Conn piston for the added fourth valve. Also, the factory silver plating was so ridiculously thick that it was actually clad on there and - when I put a new finish on it with some new glass bead blasting - the original started coming off the back of the bell in sheets, so it was a pretty weird looking back there. As I recall, the 5th valve thing that I did was pretty good. I was able to play it in tune with Alexander fingerings, but grew pretty tired of it. Others wanted to buy it, and I eventually sold it to one of them. Later, I heard it ended up being taken apart and various things were used for other instruments. I certainly didn't give a crap.
That person's ego about what you report is really something else. If I sensed that someone was that nuts, I don't think I would have communicated with them ever again, once I made a transaction and purchased something from them.
Speaking of cimbasso rentals, someone local to me was attempting to charge one of my friends something like $800 a week to rent theirs for a local opera thing. I think they said "no thanks."
There's no way that I would loan mine out nor rent it out. It requires some becoming accustomed to the instrument to be able to avoid trashing it or even bumping it against things.
I'm glad to allow people who come here to have repairs done or to buy things play it. I might discourage those who already own one from playing mine, because it would just discourage them.
To be clear, I don't fault the renter for asking that price, nor the rentee for politely saying no. I loan out stuff regularly, but nothing too precious or irreplaceable.
