I just picked up a 79 Kramer (aluminum neck) - the sound is killer, but it's a hefty bass with notable neck dive. I currently have a 2.5" leather strap, and find that the neck falls level if I take my hand off the neck or my right forearm off the body. I'm looking for a strap to take some of the weight off, but more importantly to stop the bass from the falling (no slippage). I've searched TB and am listing some of the higher rated straps. Unfortunately my local music stores do not have any of the models listed in stock, so I can't try them out. If you've overcome a similar problem - please let me know what strap did it!
