Gibson 496T

Re: Gibson 496T

Sorry to be dense, but unless you've personally took apart and count the turns of the wire, you can't say that's something you KNOW. That's something you read somewhere, most probably put out by Gibson, and as the specs Little Pigbacon copied from Gibson, you could see for yourself that they were so wrong that they made non sense at all.

I haven't dissected the newer p'ups like the 59 Tribute or the 61, however, I did have with several BBs and what I found was exactly what I said: both bobbins had the same amount of turns. That's the "collateral damage" that people that repair, mod and rewind p'ups "suffer". They take measures of everything they do, so, they learn things... and when they say something, it's because they DO KNOW.

I guess you don't know what is my job in the real life. I am an aerospace engineer and my business is provide modifications to enhance mechnical and electrical systems of aicraft and helicopters. Investigations, testing, measurements, approvals are the basis of my main occupation. And I do that every day. A pickup is a beautiful thing but it doesn't fly, hence it can not fall down. Do you really think I am the kind of person that reads something on a website or an a magazine or on a paper and thinks it is absolute truth without asking to myself anything? If you think that you are wrong. I am (poor me) an inquiring mind. Said that, I really wanted to know infos about BB, your experience and data about that. English is not my native language, so if was rude, it was not my intention. Sharing info, experience and improving knowledge is the final scope of this forum and I use it this way. I have never written anything without knowledge of it.
Now if you don't mind I want to explain how I know (opss I do not write in bold or in uppercase) BB has unbalanced coils. I am going to reveal a secret: I simply measure ( it is your method, isn't it) my pair of BB pro.
Now we can discuss if only one measurement is statistically relevant (and obviously it is not), expecially if it is compared with yours but that is my experience, nothing more..

If you're talking about DC readings, the wire's variance, even within a single spool may exceed 10%, so you just simply can't use it as as accurate unit to assess the degree of mismatch, if any.

Only turn counting offer an accurate answer to that question, and that's the method I've used to base my statements on. Also, the definition of what a mismatch is might be different for the both of us.

For example, using the same AWG#42 gauge of wire, but one being max-nom and the other min-nom, 5,000 turns of each wire would result in one coil measuring about 3,740 ohms and the other 3,925 ohms. Is that a mismatch to you? The answer is NO.

OTOH, if using the same example using AWG#42 max-nom and min-nom wire, both coils measure 3,740 ohms, but one has 5,000 turns and the other 4,825 turns. Is that a mismatch to you? The answer is YES.

However, by DC reading alone, you'll assume exactly the opposite.

So... has anyone played on a 496T?
