I play an EBMM Bongo 5 in a band I gig regularly with. I love the quality and sound of the instrument, but it's uncomfortable to wear for any time at all. Not only is it a heavy beast, but it tends to neck-dive (both while standing and sitting). The neck-diving is killing my left shoulder (I'm a right-handed player).
I know that it's possible to tinker with the balance of the instrument by relocating strap pins (aka strap buttons), usually the one on the butt-end of the instrument. My guess is that adding a second-pin closer to the top side of the instrument might alleviate the neck dive, but I thought I'd consult the experts here before making such a change.
Who here has experience fixing neck-diving basses? What things work, and what don't? How does different positioning of the strap pins effect instrument balance?
UPDATE: I should have mentioned from the start that I already use a 4-inch wide padded leather strap, and that doesn't help much with the comfort/balance issue.
