No matter if your job is big or small, we want the opportunity to earn your business.


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 for Ken Fisher of Trainwreck. If you know anything about Ken, you 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 we earned his approval. We have had the opportunity to help design and manufacture thousands of transformers for legendary amp designers and have been referred to as the industry's secret sauce for decades by many of them, but have only served OEMs until now.

In our quest to build the absolute best-sounding magnetics, we partnered with guitar amplifier icon, George Alessandro. Between our capabilities and his unparalleled knowledge of amplifier circuitry and ear, we developed a truly unique line of power transformers, output transformers, chokes, and reverb drivers that will provide musicians a more inspiring tonal pallet to craft their music from.
