Divided By 13 · amplifier
The Divided By 13 JRT 9/15 is a 9 or 15-watt switchable all-tube combo from Divided By 13, the boutique amplifier company built by Fred Taccone. JRT encodes the voicing character alongside built-in reverb and tremolo. Hand-wired point-to-point construction provides exceptional touch sensitivity and dynamic response. At 9W output tubes saturate at intimate venue and recording volumes; at 15W more headroom is available before natural breakup. Favoured by players in blues, country, Americana, and vintage rock who prize feel and dynamic nuance over raw power.
