Super Hard-On impedance

ryansalmond · #1 08-09-2009, 02:09 AM

I was intrigued when I read the following quote, and want to know if you physics experts could tell me if the super hardon could actually BE strengthening the magnetic fields around the pickups, or just has an equivalent effect, making it sound AS THOUGH the magnetic fields were stronger.

From the ZVex website: "Most vintage guitars suffer from steadily deteriorating magnets in their pickups, since permanent magnets aren't really forever. The Super Hard-On's input impedance is so high (>5 Meg) that it refuses any current flow from your pickup... maintaining the most magnetic field around each string, so you can hear exactly what your pickup sounded like the day it came off the winder."

I thought Super Hard-On impedance was when you REALLY like a girl but she won't even acknowledge your existence...

Ha! Or when age and drinking and smoking catch up with you and you can't... better not finish that sentence.

I hadn't even noticed the innuendo in the thread title

No preamplifier/booster can strength the magnetic fields of any pickup. Physically or “virtually”. The SHO is no exception.

High input impedance devices can, under certain circumstances, make the guitar sound louder and cleaner because they offer a lower load to the pickups.

Unlikely other devices, the ZVex SHO has variable input impedance. The impedance seen be the pickups changes with the position of the gain knob.

Regarding “maintaining the most magnetic field around each string”, with the greatest respect for ZVex, I would be interested to see the equations that substantiate the claim.

You are welcome ryansalmond.

If you need more details about the SHO please feel free to contact me with a PM.
