Can the Psyclone Hot be ordered with a 4-conductor cable?

Interesting. You do that in parallel? Wouldn't that roll off a bit of high-end? My de-mud does 1 nF, (.001 uf), in series. Just curious.

Of course, it rolls off a bit of high-end... but it also rises the Q factor of the resonant peak in the same time than it lowers its pitch, just like explained here: zerocapcable.com/?page_id=209

That's how I lead a Filter'Tron to mimic sonically a Gibson style HB.

In order to contextualize my explanations, let's share below the electrically induced resonant frequencies of various pickups on a linear scale.

First pic = a regular Filter'Tron HB (in red) vs a Strat PU, a lipstick, a Tri-Sonic. Paradoxically, the Filter'Tron is higher pitched and has more high frequencies than any of the three single coils...

2d pic = each coil of a T-Top vs each coil of a Filter'Tron. I've decided to use the linear scale because it clearly shows the higher Q factor of the T-Top despite of its lower pitched resonant peak.

A cap of several nF in parallel with a regular FT just drags down its resonance and makes it narrower (IOW: with a higher Q factor), which makes it sound closer to a T-Top.

Thanks. This is interesting because I perceive my Psyclones to be similar, tonal wise, to my Lipstick Tubes, but obviously, with more output. Let me study those graphs a little more.

And, as always, thanks for your efforts.

How do you get those graphs?

Well, Psyclones having more DCR than regular FT's, they might have a higher inductance as well... and anyway, the differently shaped magnetic field / string sensing aperture of a Filter'Tron makes it bassier than a lipstick, although it resonates higher.

Regarding the graphs, my friends and me do what Helmuth Lemme does for a long time and that many others have imitated - we excite electrically the pickups with ultra-low impedance air coils as explained here: http://www.buildyourguitar.com/resources/lemme/


The only difference is that we don't use here any "integrator" to obtain a flat response from the pickups. We follow other strategies to make obvious things like Foucault currents.

EDIT - Helmuth Lemme was also among the first to promote so clearly parallel caps as a way to "tune" resonant frequencies, BTW. It's explained in the page above. To be honest, It's not him who has inspired me. Seymour or Bill Lawrence already toyed with low value caps decades before us, anyway; but at least the page shared by Lemme is clear on this subject and that's another reason to share the related link.

Reading, as we speak.
