The old truism "There's always a first time" proved true last week. I've settled on using SS DR LoRiders on my two four-strings and my fiver and re-stringing them all at the same time. After retrieving my order from my mailbox last weekend, I re-strung my fours with no problems but when I started to install fresh strings on my fiver, I discovered that the B was missing from the set. When speaking with Julian @ Bass Strings Online, he discovered that the last set they had in stock was also missing the B string. It does apparently 'happen to the best of them'. Julian initiated a warranty claim (this was on this past Monday). Now all I have to do is wait and see how long it takes to get what should have been in the box from the get-go...
Thanks, again Jason!
