Out of curiosity, is Slider the only company who makes a bass harness? The idea sounds good in theory, but most folks here say that the Slider harness is difficult to put on, has zero padding (can't be good for circulation,) and puts your bass in an uncomfortable position unless it's worn upside down. I tend to favor heavier basses (i.e. 6-string) and while I'm relatively young (26,) fit (I lift 3x weekly,) and sitting pretty with a 3" wide Kepur strap the last thing I need is compounded back (particularly lower) problems in the future (6 years in saggy dorm bedframes killed my back. Nowadays, I don't even sleep on a bed- just a mattress on the floor; better for my back.) The idea of a strap that distributes the weight over both shoulders and the back without needing to rout out another hole in one's bass seems sound and would help to alleviate and maybe be a proactive preventative measure for future back problems, but are there any other companies besides Slider who make better harnesses in terms of comofort and ergonomics?
