Vintage accurate sound is all about making the right choices.

At Metroamp, we get a little freaky about the details. And if you're talking about transformers, the details matter.

Back in the early days of Marshall production, variances and loose tolerances were responsible for the phenomenon of 5 seemingly-identical Marshall heads sounding quite different. This was particularly true regarding the selection of transformers. Back then, choosing a transformer often came down to what was readily available on any given day. And sometimes that meant using less than ideal parts.

Using history as our guide (and a breathtaking selection of vintage "perfect example" amps for precise measurement), Metroamp has created a "perfect world" scenario: We measure every original part, down to it's finest detail and spec, and we only buy, sell, and use parts that are a perfect match to the original. If a perfect match is not found, we have them custom built to spec, down to the mil of the metal, original stamping, the works. It's a level of consistency and quality control they'd have killed for back in the day.

From our custom built vintage-accurate Marshall replica amplifiers to our DIY amp kits, our transformers are the real deal. You will hear the difference.
