Based on the famous RSA23 amplifier, in collaboration with Brian Ray (of Paul McCartney ́s band), Divided by 13 presents the BTR23 model. In essence it’s an amplifier that brings the best of English models, combining the sensitivity and dynamics of those equipped with EL84 tubes, to the powerful heads with KT88 tubes (chosen for this model), full of roar, power and creaminess, recognizable in thousands of classic and modern recordings.


Its 23 watts of power “Class A / B”, turn it to an ideal amplifier, both for live performances and for studio purposes. The preamp includes an extra MID frequencies control and gives us a complete tonal spectrum.


We also have a MID Boost, in push / pull mode that is activated by pulling the Volume button.


All Divided by 13 amplifiers are built with passion by the best professionals in Southern California.
