First impressions were when the postman said "It's a bit heavy, mind!" - he wasn't kidding. On opening the box and pulling it out, I can see why it's called the Hercules . . . it looks and feels as though it was designed to be fully up to the weight and size of a BBb tuba, and no messing. The legs are adjustable for angle, so though I've got them on a pitch circle of about 20" diameter (50cms), which gives ample stability with my baritone on board, there is plenty of adjustment left to open them up a lot more to lower a tuba and increase the circle of support if you wish, and I've no doubt it would be rock steady. My baritone looks like it's cradled by a chunk they nicked out of the Forth Bridge . . .
The instructions on the box are not quite clear about how to engage the locking pin which holds the horizontal arm in position, but after a few seconds of fiddling, I got it done. The support arms are covered in a stiff foam rubber / plastic, which the makers say is formulated to avoid marring instrument finish, and it looks and feels the right consistency to cushion the instrument without being too soft and squashing flat.
Re. the size adjustment; I have the width between the support brackets at minimum, but then my bari is a John Packer 173, medium bore, with an 8" bell - so probably as small a baritone as you can get - nonetheless, it is perfectly secure. I also found by adjusting the height of the longer support arm, I could set it so that the radius of the support bracket matched that of the bell where the two touched, making the instrument feel really stable on the stand, with no tendency to rock about.
And the price? Amazingly, it's the LOWEST priced stand for a baritone horn I could find anywhere!
