Fishman Fluence

Found this article to be interesting and figured it might generate some discussion here. For the technology, I'm kind of surprised it hasn't happened already as it doesn't seem like too radical of an idea.

Fishman Fluence

In short, if you don't want to read the article. The pickups consists of 46-layers of printed circuit boards with the traces simulating the typical winding of copper wire. These are active pickups, but the kicker is they'll incorporate a rechargeable battery (lasts 250 hours per charge), and a preamp to select two distinct voicings of the pickup. To be revealed at NAMM 2014.

I'm wondering if as the battery is dying if the sounds will change much the voltage sag in some pedals?

Thanks for posting that.

In addition to other features, Id expect they have good resistance to microphonic feedback too, with no beeswax needed!

On the idea of tuning the tone (with caps) and with active output and long battery life, no big deal there, we can do that too with any pickup

The idea of 'printing coils' is not a new one (in other feilds as the article says), just not used much in guitars, the 'voicing' might largely be different connections to alter the number of these 'printed coils' are in circuit, altering the impedance.

Lace Alumitones are essentially this kind of thing, a single coil in the frame of aluminium and using a transformer to bring the signal up to a usable passive signal.

The magnetic side is interesting but low on detail, but they are 'stacked' to be humcancelling. Basically they seem to be 'modelled' in the preamp stage it seems.

I've been a little surprised to find that rechargable lithium batteries in miniture electronics is not seen more
