Handmade in the USA using the highest-quality components, the Supro Ambassador Custom is a genuine top-of-the-line boutique amplifier that elevates the Supro tradition to an entirely new level. This 50-/35-watt amplifier sports a trio of 12AX7 preamp tubes and two 5881/6l6WGC power tubes, resulting in a remarkably dynamic and touch-sensitive gain structure that sings with old-school valve saturation. In the classic Supro tradition, this amplifiers control section comprises a straightforward 3-band EQ, Volume knob, and lush tube-driven spring reverb. However, the Ambassador Customs combination of a Master volume and innovative Class A (35 watts)/Class AB (50 watts) switch allows you to achieve vibrant cranked overdrive tones without blowing out your ears. Even the Ambassador Customs Valco-inspired cabinet beams with masterful construction, with a unique wraparound design, dog bone handle, and poplar construction that harkens back to Supros vintage heyday. Merging the tone and looks of Supros vintage past with all the best features of the companys modern resurgence, the Ambassador Custom is a truly extraordinary tube amplifier that will go down as one of Supros all-time greats.

Top-shelf all-tube preamp

Fueled by three 12AX7 tubes, the Ambassador Custom’s preamp yields an extended frequency response, thanks to Mercury Magnetics transformers, that you can mold to perfection with a custom-voiced 3-band EQ.The guitaristshave found this amp’s touch-sensitive warmth to be eminently inspiring, and its overtone-rich sound infuses every note you play with ear-grabbing character.

2-voice Class A/Class AB switch

When testing out the Ambassador Custom, one of the features that most impressive was this amplifiers innovative Class A/Class AB switch. Not quite a voicing switch and not quite a power scaling function, this switch utterly transforms the Ambassador Customs design from Class A to Class AB circuitry.

• Class A:Clocking in at 35 watts, this mode captures the raw, inefficient, and tweed-esque rasp of Supros greatest vintage amplifiers. Rich midrange is the name of the game here, and players who worship at the bluesy hard-rock altar established by Supros most iconic models will find much to love in Class A mode.
• Class AB:This mode harnesses the Ambassador Customs full 50-watt potential. With a more scooped midrange response, quicker transients, and a firm bass. While its certainly slightly closer to the California sound, Class AB mode beautifully retains a sharp Supro edge when you start to push the Ambassador Customs front end.

Stunning Valco-inspired cabinet

The Ambassador Custom features a rugged and eye-catching poplar cabinet with a mid-century, Valco-inspired wraparound design and a sturdy dog bone handle for easy transportation. The cabinet is loaded with two Celestion BD10 Supro speakers, which provide a supremely punchy tone with a round, firm low-end response. The Ambassador Customs cabinet also includes stunning gold accents, a hemp grille cloth, and an attention-grabbing “Supro” logo.
