Well, at the moment we're at an impasse because I can't point you to a
website to prove my point.
The problem is sources. Anything off the internet is digital text, most of it dating from the 90's at the earliest and most of it is marketing stuff from manufacturers. Back in the 70's there was only print. That kind of points to how the internet is defining reality and skewing history for some people.
Here's some background:
I'm 49 and I started playing bass when I was 12 in the early 70's. By age 13 I was playing gigs. All through Jr High and HS I played with musicians who were at least 3 years older than me. I grew up in southern California. Anyways' I was there when Rotosound Swing Bass really hit the US. The Brits had them in the late 60's but they didn't hit US stores until the early 70's and even then, only a few stores would get them. Believe me, Rotosound roundwounds were a
quest for me and others who played modern bass then.
I played those strings. I know what they felt like, what they looked like, what they sounded like and how they behaved over time and in the elements. They were ALL I used from age 12 or 13 to age 21 when I stopped playing to go to college.
They were definately not what is sold today as RS66LD.
They were either the same as or much more similar to RN66LD.
Here's what I can tell you:
Number 1. The old Rotos often died quickly (lost their twang). Stainless steel strings don't do that because stainless steel doesn't corrode. The old Rotos did corrode. The old Rotos often went maddeningly dead fairly quickly (sometimes in a few days or a week). That's why Entwistle, Squire, Lake etc. changed them every show. Stainless doesn't do that.
Number 2. Nickel steel Rotos are slightly darker looking (or gray) compared to stainless. The old Rotos looked like todays RN66LD.
Number 3. The RN66LD feel more rubbery than the RS66LD - I'm talking same gauges. The old Rotos had that same somewhat rubbery feel. You could bend them fairly easily.
Number 4. The sound. The RS66LD have a more brittle harsh sound that the old Rotos didn't have. The old ones had lots of bright twang but not that brittle sound. The RN66LD sound like the old Rotos.
Number 5. I remember reading in their print literature that Swing Bass 66 were a Nickel Steel alloy. I remember when I first saw stainless at a store and thought awesome! But then I tried them and they weren't the same sound and feel. There's always a tradeoff. The stainless addresses the shorter life of the nickel steel but there's no free lunch.
Rotosound can say the original Swing Bass 66 was stainless steel all they want. Maybe the core was but the winding was certainly not. They can say the RS66LD is the old long scale swing bass 66 but that's BS. What they sell today as RS66LD is not the old string. The RN66LD is either the same as or a lot more similar to the old Swing Bass 66.
But the 60's Rotosounds are what we're talking about!
KPAX, we have the facts from multiple sources and then we have your statements, yet to be proven in any form. Look, if you had any proof of the strings being nickel, I'd love to see it. I'm not opposed to learning the truth beyond dogma, but I've yet to read anything other than what you've said that proves that they were nickel-wounds.
"Around this time James came up with a combination of Stainless Steel and round wire to produce an extremely high output bass string" - it doesn't say that it was James How's idea to produce roundwound strings, it says he put the stainless steel materials and the roundwound design together for their product. I doubt John Entwistle, despite his wanting a particular design for the bass string, knew much about the properties of metals. That was Roger's area.
I'll forward the email from Rotosound to anybody who wants it, it was signed Jason How, not James How.
