"Hey Bob, I'm pretty tall, and I have my endpin extended out more than 8" - will I be able to use this stand without adjusting the endpin each time?"
On the SA22 stand, from the standpoint of the bottom arms which support the bass, there's no issue with the endpin length;
the arms are adjustable and can be raised quite high - probably longer than your endpin could ever extend. However, the upper
cradle (which supports the neck) can only extend to a practical maximum of about 59" from the floor (measured at a slight angle to compensate for the angle of the bass in the stand - see image.) Therefore, with the bass endpin extended to the height you prefer, the top surface of the bass neck's heel
needs to be below that measurement in order to fit under the cradle (and therefore into the stand).
This means that the height limit of your endpin (to fit in the stand) depends upon the body size of the instrument. The maximum height from the floor (endpin extended) to joint where the upper bout meets the base of the neck would be about 58". It's why the stand can easily hold the Eminence Electric Upright Bass, despite having an endpin that's extended over a foot long - the body is much smaller, and the height at the heel of the neck is still under 59".
So, for instance, if your bass's body, from the *top* of the heel of the neck to the endpin collar, is 47" (as is Bob's Kay M1), this would leave you enough clearance to have the endpin comfortably extended 10" from the body with still an inch left between the tip and the floor (58" - 47" = 11").
So measure the bass from the bottom point of the back of the body up to the uppermost horizontal point on the neck heel. If this measurement is 47.5" or less, you should be able to put your bass in the stand with the endpin out as much as 10" (measured from the bottom of the bass body).
Hopefully, this clears it up for you!
