SoZo's Yellow Mustard line of polyester film tube amp capacitors have been thoroughly tested by LA’s best tube amp builders. They are handmade to exact vintage specs, and beat everything available, even in high gain situations.

These caps are successful recreations of the originals and are superbly built and excellent-sounding caps.

This is the classic value for humbuckers and P90's

It is also very good in P and J bass guitars where a more gentle effect is called for.
