The Subject is Sprio REDS, the Mediums only. The size of your bass will determine which set you get, the S42s or the 3885s, All the other models and gauges are irrelevant at the moment as far as my question goes.
S42 4/4 Medium 61.4 65.5 69.6 69.6 = 266.1
3885 3/4 Medium 67.2 68.3 70.5 72.8 = 278.8
What do these numbers mean under my fingers and on my Neck or Bow? The 4/4 set is lower then the 3/4 set? When I ordered a normal set they sent me the 3885s according to my invoice. But, when I ordered a C ext. string for that same set, it was a C S44.
So, regardless of which length you need, the Red's are the Red's because you can't use a string too long or short for your bass.
As far as Tuning Peg placement goes, the reverse placement idea came from the French, back in the 19th century. The New Standards from Arnold and Wil come with reverse gears as well and have so for as long as I have known those basses. Many early-mid 20th century German basses from both Meyer and Pollmann have reverse tuners as well as 2 on the bass side of the 5ers. They too have realized the need for more after length on thicker strings. But, it is not so easy sometimes with reverse tuners to put a low C-extension on and use the top gear. In this case, the lower gear normal E post would be the longer after length for the E/C string.
The best way I have found for the Low E with standard placement of the gears is to put the E on the upper Gear like it would be if you had a C extension. This way, when switching back between a regular 4 and a bass with Ext., the E and A are on the same posts. On my 5er, I have 3 gears on the bass side so I put the A lowest, E middle and B the upper most peg, usually for the A. So in this case, the B switched with the A giving way to the larger string to be the longest after length. Ok, END of off topic!..
So, who here has experience with Orchestral Bowing using Spiro Reds, Medium gauge, Red at both ends?
