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 value works really well in the neck position pickup and evens out the perceived treble roll off compared to the bridge position with a 0.022uf capacitor.

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