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.

Last August, metalcore giants Poison the Well gave the world a gift: They announced they were working on their first studio album in 15 years. They unleashed the first taste, single “Trembling Level,” back in January, and set off on a spring North American tour during which they played their debut record, The Opposite of December… A Season of Separation, in full every night.
PG’s Perry Bean caught up with guitarists Ryan Primack and Vadim Taver, and bassist Noah Harmon, ahead of the band’s show at Nashville’s Brooklyn Bowl for this new Rig Rundown.
Brought to you by D’Addario.Not-So-Quiet As a Mouse
Primack started his playing career on Telecasters, then switched to Les Pauls, but when his prized LPs were stolen, he jumped back to Teles, and now owns nine of them.
His No. 1 is this white one (left). Seymour Duncan made him a JB Model pickup in a single-coil size for the bridge position, while the neck is a Seymour Duncan Quarter Pound Staggered. He ripped out all the electronics, added a Gibson-style toggle switch, flipped the control plate orientation thanks to an obsession with Danny Gatton, and included just one steel knob to control tone. Primack also installed string trees with foam to control extra noise.
This one has Ernie Ball Papa Het’s Hardwired strings, .011–.050.
Here, Kitty, Kitty
Primack runs both a PRS Archon and a Bad Cat Lynx at the same time, covering both 6L6 and EL34 territories. The Lynx goes into a Friedman 4x12 cab that’s been rebadged in honor of its nickname, “Donkey,” while the Archon, which is like a “refined 5150,” runs through an Orange 4x12.
Ryan Primack’s Pedalboard
Primack’s board sports a Saturnworks True Bypass Multi Looper, plus two Saturnworks boost pedals. The rest includes a Boss TU-3w, DOD Bifet Boost 410, Caroline Electronics Hawaiian Pizza, Fortin ZUUL +, MXR Phase 100, JHS Series 3 Tremolo, Boss DM-2w, DOD Rubberneck, MXR Carbon Copy Deluxe, Walrus Slo, and SolidGoldFX Surf Rider III.
Taver’s Teles
Vadim Taver’s go-to is this cherryburst Fender Telecaster, which he scored in the early 2000s and has been upgraded to Seymour Duncan pickups on Primack’s recommendation. His white Balaguer T-style has been treated to the same upgrade. The Balaguer is tuned to drop C, and the Fender stays in D standard. Both have D’Addario strings, with a slightly heavier gauge on the Balaguer.
Dual-Channel Chugger
Taver loves his 2-channel Orange Rockerverb 100s, one of which lives in a case made right in Nashville.
Vadim Taver’s Pedalboard
Taver’s board includes an MXR Joshua, MXR Carbon Copy Deluxe, Empress Tremolo, Walrus ARP-87, Old Blood Noise Endeavors Reflector, MXR Phase 90, Boss CE-2w, and Sonic Research Turbo Tuner ST-200, all powered by a Voodoo Lab Pedal Power 2 Plus.
Big Duff
Harmon’s favorite these days is this Fender Duff McKagan Deluxe Precision Bass, which he’s outfitted with a Leo Quan Badass bridge. His backup is a Mexico-made Fender Classic Series ’70s Jazz Bass. This one also sports Primack-picked pickups.
Rental Rockers
Harmon rented this Orange AD200B MK III head, which runs through a 1x15 cab on top and a 4x10 on the bottom.
Noah Harmon’s Pedalboard
Harmon’s board carries a Boss TU-2, Boss ODB-3, MXR Dyna Comp, Darkglass Electronics Vintage Ultra, and a Voodoo Lab Pedal Power 2 Plus. His signal from the Vintage Ultra runs right to the front-of-house, and Harmon estimates that that signal accounts for about half of what people hear on any given night.
