Re: Incoming New Pickup Day (Fishman Fluence)
Frank you sound like such a nerd... and it's freaking awesome!
Rick's a smart guy, and a friend. He does understand these things, and what he says about the Piezo in an acoustic guitar is correct, but almost inversely proportionate for electric guitar. Perhaps a thread like this is more what you're looking for?: http://music-electronics-forum.com/t35354/
Rick chimes in toward the end, and we spend much more time on details. The short version is that small delays and stacking up of different sound sources will produce anomalies that are not EQ based. Learn about things like comb filtering, and how you can't just EQ those things back into a sound. And even if you could, they change and move with every different note you'd play because they vary based on the harmonic stacking. Even things like outside strings that have no magnet on the other side of them, vs inside strings that have strings and magnets on both sides all play a role in what we've become accustomed to hearing through our past experiences, but also what we want to hear, and the two are indeed different.
Taken a little bit deeper, the phase anomalies that we can impart into the sound that are the result of the magnetic field, as in stray flux lines, conflicting flux patterns, etc. are all desirable. It's why a Strat pickup responds like a Strat pickup, and a Strat pickup with a blade, or steel poles and Ceramic base magnets just aren't "right". Inductance and tonal spectrum aside, the flux disturbance is a large part of when we know a pickup is right, and when it feels wrong. That, however is NOT exclusively the phase incoherence I'm referring to within the coil layers. That's different. To bring that element into focus; to reduce things like group delay there, is pretty much a universal win/win for everyone. That's the part where people say "It sounds like my 54 Strat, but better" (and yes that's an actual quote from a respected industry veteran WITH an actual 54 Strat...original)
How does this play out practically? Take a vintage strat pickup for example, like those SSL-1's you've just received. They are excellent pickups, until you want something slightly different. Traditional pickup making is wrought with compromise, which is why there are so many different (and valid) models. Its like squeezing a balloon. You get one part right and something else pops up somewhere else. You get this part big and the other part is small. Such is the life of a pickup maker: "I love it but can I have just a little more "X?" and the answer is "Yes, but you'll lose a little "Y" but I can compensate for that by doing a bunch of other things" and eventually the player is happy...for a while anywayThe freedoms inherent in this technology are staggering.
