Interesting point regarding the JMJ Mustang using Fender long scale flats - I had no idea that was the case and can clearly see on the Fender website the E and A strings (not the silks) wrapped around the tuning posts!
My apologies, the fingerboard radius is 12 inches, not 14 as stated above. Another senior moment!
Many thanks to the eagle-eyed BC’er for highlighting to me.
Well worth an email with details of the cables. I wrote and asked them for if my custom shop cable was still available. It wasn’t but they offered one that was most similar. I’m more than happy - great customer service.
Nicely set up with a new set of Fender 7150s (vintage nickel roundwounds). It has a low action and the combination of a 14 inch radius fretboard and satin finish on the back of the neck, makes for a great playing (and sounding!) bass.
Fender Nickel Plated Steel I believe. 45 - 105. Do yours have the coloured ball ends, red, green, silver and brass? These are the usual Fender colours.
