Cavity Noise Canceling System (CVNCS)

For guitar with back cavity

The Cavity Noise Canceling System is designed for noise cancellation of single coil pickups having resistance from about 5-6Kohm up to 9-10KOhm.

General requirements:

1. All single coil pickups need to be same magnetic polarity and same winding direction (NO RWRP)

2. The pickups switching does NOT have to include any "in series" pickups connection

The large noise canceling coil 

is shaped to fit and placed inside of the control cavity.

It is suitable for guitars having larger sized and deeper 

"square-round" (rhombic) shape control cavity.

A good size control cavity will have more than

13 inches circumference length and about 3/4 inch depth.

Recommended for P90 or similar style of pickups 
which read about 6.5KOhm up to about 8KOhm resistance

The large noise canceling coil 

is constructed to replace the original control cavity cover.

It has plastic core, same screw hole pattern and it is 
mounted using the original cavity cover screws.
Recommended for P90 or similar style of pickups 
which read about 7.0KOhm up to about 9KOhm resistance

The large noise canceling coil 

is shaped to match the original control cavity rhombic shape.

It is placed on the middle back of the guitar body using 

double-sided tape or some other taping technique.
Recommended for P90 or similar style of pickups 
which read about 7.0KOhm up to about 9KOhm resistance

The large noise canceling coil has circled shape. 

It is placed on the middle back of the guitar body using 

double-sided tape or some other taping technique.
Recommended for P90 or similar style of pickups 
which read about 7.0KOhm up to about 9KOhm resistance

The large noise canceling coil 

has rounded shape and satin finish plastic cover. 

It is placed on the middle back of the guitar body using 

double-sided tape or some other taping technique.
Recommended for P90 or similar style of pickups 
which read about 7.0KOhm up to about 9KOhm resistance
