Similarity
citedBlended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.

Description

The Divided By 13 BTR 23 is a 23-watt all-tube amplifier from Divided By 13, with built-in reverb and tremolo. Hand-wired point-to-point construction in the boutique Fred Taccone tradition provides touch sensitivity and harmonic complexity. At 23 watts it balances between the smaller 9/15W D13 models and the 37W FTR, suited to small venue gigging and studio use. Divided By 13 amps are known for their exceptional dynamic response and feel, particularly among blues, country, and Americana players.

The Supro 1668RT Jupiter is positioned as the high-headroom amplifier in the Supro range, built to deliver the punch and stage volume that the smaller vintage-reissue models cannot while retaining the fundamental dynamics and tonal character the brand is known for. Supro describe it as suiting rock, funk, fusion, jazz and electronic music, which reflects a design built around clean power and responsiveness rather than early breakup. That makes it the natural choice within the line for players who need the amp to stay clear at band volume, and a more capable pedal platform than the low-wattage Supro combos. It suits players across a wide stylistic range who want Supro character without sacrificing headroom.
