Mustard Cap™ - The Marshall™, Neve™, Vox™ and Hiwatt™ Clone Capacitors
The leads on SoZo Mustard Caps capacitor are a superior tin coated pure copper lead style, which aid in replicating the sound they strove to reproduce. They are not the cheaper copper clad steel which deliver only 30% of pure coppers conductivity. SoZo found the length of the capacitor in reference to the diameter participates in the behavior of the frequencies and current delivery rate of the capacitor (called its slew rate). Keeping the same dimensions dramatically changed the sound and the capacitor was again made true to the original. The result is the audio signal leaves the capacitor at the same rate as the original retaining its performance. It will take up to 100 hours of break in for the capacitor to operate to its full potential. The dielectric will polarize and develop a pattern creating a clearer, full frequency sound.
How does this translate into sound? SoZo is of the opinion that this is a successful recreation of the original and a superbly built and sounding capacitor. When one considers the audio signal passes through as many as ten capacitors before exiting the amplifier, you can see how these components play an extremely large role in the tone of the amplifier.
All capacitors meet MIL-STD. 202 C, Method 103 B ± 5% tolerance. Every single capacitor fully tested!
Some User Comments:
I just installed SOZO's in my '76 Marshall SL 100, an amp that I've fully converted to 67 era Plexi spec's. I had previously swapped out the original green caps with Mallory's which made an improvement, but still didn't take it to "Mustard" territory. But now that the SOZO's are in, that smoothness and clarity is all there with much more pronounced harmonics. Low end is much more focused. I'd dare to say that John has one-upped the Mustards!
Well, I have built 2 identical Metro 100 watt clones except one with SOZO caps and one that has NOS mustards that I paid a ridiculous amount of money for. The results? With my Les Paul 1959R, I can't tell the difference between the two amps. They sound identical!
If I had to say how close the the SoZo's sound to the mustards...Id have to say they are 99.9% exact...and to me ... I cant tell the .1% difference...and they were about $200 cheaper!
