Eugene,
Apologies for the late reply, I've been away from home for a while.
On revision of what I said re the 5 positions, Stuart 'read my mind' there, I should have been more explicit! On the early 'box' type selectors fitted to the Marvins, with constant use the 'click' points quickly wore down and the switch simply 'slides' through the whole range of settings - I found that I was more often setting it by 'sound' rather than 'feel'. If you ever have a close look at one of those switches you will see that they have two double rows of parallel connections, over which slide a set (four from memory) of shuttles, all in a straight line, the actual toggle simply moves the shuttles from one end of the box to the other -'simple' British engineering at its best as my USA friends would say! As Stuart has pointed out, the same 'half way' position was available and well known to early Strat players when the original 3 position switch was OEM on Strats, but eventually the 5 position switch became the norm.
As an aside, if you have a look at the BALDWIN Marvins in this clip you will see that they have a fourth knob, which I believe is a rotary switch since the original toggle is not visible......
