Both models feature ultra-premium componentry, including Mercury Magnetics transformers, vintage-correct Mallory capacitors, precision-matched EHX tubes, and custom Celestion speakers.
Supro announces Supro Custom Amplifiers—a new collection of bespoke tube amplifiers hand-built in the USA. Two new models—the Delegate Custom 1x12 and Ambassador Custom 2x10—were designed to redefine the Supro tube amp tone.
The Supro Delegate Custom is a 25-watt 1x12 combo voiced to provide world-class touch sensitivity, exceptional midrange warmth, and rock & roll grind. Its unique circuit topology is designed to optimize the amp’s top-shelf components, providing a wide-open, immediate sound that captures the distinct tonal characteristics that define the Supro sound within the pantheon of legendary electric guitar tones. Gushing overdrive and a hearth of warm mids allow the Delegate to sing at any volume. Every element within the amplifier has been selected to provide a broadband sound rich in even harmonic color and deeply responsive to your instrument.
The preamp in the Supro Delegate employs a trio of 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. It delivers remarkably tactile response and blooming overtones across the full range of the guitar. 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 Cathode-biased power amp.
The Delegate’s Class-A output stage uses a pair of Electro Harmonix 6V6 tubes to deliver loads of natural tube compression and an exceptionally low noise floor, while its versatility allows for seamless transition from sparkling cleans into glorious tube overdrive. A dream for players who enjoy the responsiveness that occurs when you crank up the preamp while using the guitar’s volume control to adjust the texture of the amp’s tone, the Supro Delegate Custom is ideally suited for both stage use and studio recording.
The Supro Ambassador Custom is a 50-watt 2x10 combo amp equipped with two custom BD10 Supro speakers built by Celestion. 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 capture the full, 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.
The Delegate Custom 1x12 and Ambassador Custom 2x10 are available in two colorways. Their unique Valco-inspired wraparound cabinets are dressed in a custom Scandia tolex—Black or Burgundy—with gold accents, complementing gold-topped knobs and a brushed gold headplate.
Both amps are now available for pre-order in limited quantities at select dealers worldwide.
