Interesting question. Here are some thoughts.
I read George Geddes's booklet on Burns Marvins again with interest. In particular the section of the Fender / Marvin transition where he goes into some detail and confirms it took 2 years. As mentioned in Paul Day's book and Barry Gibson's site: According to Hank, around 30 prototypes of the new model were assembled before the guitar finally met with his approval. "The 24 months of waiting was a nuisance but it all seemed worthwhile when we first began to use them," Marvin told the readers of his Beat Monthly column.
That works out at a prototype every 24 days........!
Given the importance / fame of The Shads and the simplicity of the brief 'to produce a Strat clone'(!?!), I would assume that Jim would have jumped-to and had the first prototype in Hank's hands as quickly as it was possible to ensure Hank did not change his mind. With this in mind, the only real design challenge would be to engineer a vibrato that was stable, offered easy string changing and avoided the Fender's patents. Having completed a number of vibrato designs including the design of the 4 pickup Bison in December 1961, this would have been a relatively simple challenge for Jim and his team/suppliers.
George tells me he has seen a picture of a Marvin 'plank with no embellishment' but has no knowledge of its dates. Do you know of anyone who has any detail of the Marvin development project or a possible timeline? Do you know the dates of the design registration applications for the neck and vibrato numbers 917831&2 mentioned in Paul Day's book?
My experience of new product development and design management would suggest a project of this nature establishes the basics fairly quickly with most of the time taken with the toing and froing the various prototypes while the design detail and cosmetics are resolved. Paul Day and George identify some of the detailed developments:
- the subsequent addition of the small scratchplate to the upper bout
- changing the 3 way switch to a 5 way
- the subsequent addition of the hand-rest on the vibrato
- a larger black rear surround
- changes to the engraving
- a wider neck
- the scroll headstock
- the addition of an extra fret
Per claims the early examples had a rotary switch. And I heard somewhere that Hank had the scratchplate moved nearer the bridge to give a brighter sound, while Bruce had his vibrato screwed down for stability.
The point of listing the above is that the fundamental changes that would effect the 'sound' are not reported and given the simplicity of Hank's brief to Jim 'produce a Strat clone' I would not have expected anything of significance. As a consequence, I suggest Jim would have supplied a very playable guitar early in the two year development programme. If this was the case, Hank's first response would have been to try it through an AC30 and test it in the studio, even though it was not ready for stage-work and presentation to the public!
This takes me to the nub of my question: why did The Shads first and second LPs sound so different? Could tracks such as The Rumble & South of The Border on Out of The Shadows (that were recorded in April & May of 1962) have been played on a first, second, third or fourth generation Burns Marvin prototypes?
No doubt some of you will have some insight that sinks this hypothesis……….
