I just picked up a Gruvgear Duo strap for my gecko bass which is really too heavy for gigging purposes. At first I was not sure if I liked it but after some adjusting I love it. It spreads the weight of the bass over both shoulders and basically makes a very heavy bass feel like a light instrument. It will not be for every one I think it may not be long enough for tall people who like to hang their instruments super low but I am 6'4" and at the longest position it hangs my bass in the perfect spot. One more benefit I found is it allows me to tilt the bass upward a bit more with out having to push it, this helps get the perfect playing position which helps especially with the long scale of the Gecko. I highly recommend this to anyone who has an instrument that they tend not to want to stand up with due to weight. They say their is an attachment for single cut guitars and basses, i have not seen or tried this but it may help with those extra heavy Les Paul type guitars we all hate to love so much.
