Leo was a great kind man, humble and never claimed he was an inventor, he was a tinkerer/engineer. The people he worked with often supplied the details, and the designs for the body styles. He came up with innovations, not invention.
I unlike many if not ALL of you,
knew, and worked with him. I drove him home several times, and ate lunch with him.
Dale, and George were strong contributors to the designs, and actual products.
Answer to the question, he took pride in all of his products. Each in turn was his best effort, a progression from his previous product.
His drive was to put a useful intrument in the hands of as many people that desired it.
Pride in his own legacy, yet felt that everything could be improved upon in some way.
The caster was a proof of concept, the strat, the evolution.
The first precision, an item to fill a need he percieved (guitarist to play low notes)
The Jazz to answer the need for tonal variation.
He did NOT play and was darn near deaf.
Keep also in mind that Rickenbacker was a few miles from either the original factory site or the "lab" which became Music Man, and later G&L
Bless you Leo, you are missed.
Discuss but respect the humble, kind man that he was.
