Built by hand in the USA, the Supro Ambassador Custom is a 50-watt 2x10 combo amp that utilizes ultra-premium components to deliver the pinnacle of Supro tube amp tone. Housed in a mid-century, Valco-inspired wraparound cabinet and voiced to offer enormous, vivid tone, the Ambassador comes loaded with top-of-the-line Mercury Magnetics transformers, vintage-correct Mallory capacitors, precision-matched EHX tubes, tube-driven spring reverb and a pair of custom BD10 Supro speakers built by Celestion.

The Ambassador’s unique circuit topology is designed to squeeze every drop of performance out of the amp’s top-shelf components. It offers copious headroom, yielding massive clean tones that give way to sweet overdrive only at the highest volumes—ideal for players who float across the genre spectrum and desire a top-of-the-line tube amp that can deliver premium rock, funk, and R&B tones. Every element within the Ambassador has been selected to provide a broadband sound—rich in even harmonics, reflective of the true nature of your instrument, and an excellent platform for pedals.

The preamp in the Supro Ambassador features three 12AX7 tubes and a specially-voiced 3-band EQ to make the most of the extended frequency response derived from the Mercury Magnetics transformer set. Immediately following the preamp comes the signature Supro paraphase inverter stage followed by a master volume control that is optimally located within the circuit to preserve frequency response as well as the dynamic interaction between the all-tube preamp, 12AT7-driven spring reverb and variable-wattage power amp.

The Ambassador features a switchable Class A (35 Watt) / Class AB (50 Watt) output stage loaded with EHX 5881/6L6WGC power tubes to deliver responsive articulation and an exceptionally low noise floor even at full volume. Class A mode delivers the more traditional, cathode-biased Supro sound with a bold midrange, while Class AB delivers a grid-biased California sound with a more scooped mid-range, tighter bass and faster transient response. Perfect for players looking for loud, colorful cleans and a hefty bottom end, the Supro Ambassador Custom offers iconic tone both onstage and in-studio.
