Pacific Audio Magnetics

We have designed and built transformers for the most iconic amplifiers in history

For 40 years, Pacific Transformer has been designing guitar amplifier magnetics for some of the most iconic amps ever built. Some of our first jobs were rewinding early Marshall Plexis. From there, our reputation grew. One of our most well-known designs was the Trainwreck amplifier for Ken Fischer. This amp is considered by many to be the greatest guitar amp ever made. If you know anything about Ken, you will know how obsessive he was in his quest to build his amps. He chose Pacific Transformer to deliver the exact sound he was looking for and earned his approval. It’s a safe bet that the majority of highly reviewed amps you currently read about are running on Pacific Transformer designs.
