Hagerman launches a pair of tube-driven pedals

Driven by a 12AX7 and en EF86 respectively.

Hagerman has launched a pair of vacuum tube-driven pedals: the Boost, driven by an EF86, and the Overdrive, driven by a 12AX7.

The Boost is all-analogue and uses a pentode to provide warm, clean gain to push a clean sound or overdrive an amplifier. The pedal’s two volume and tone knobs govern the output and EQ respectively. The Boost also features true-bypass switching and a built-in low-noise boost converter that runs the EF86 tube at the correct voltage without affecting the signal.

The Overdrive is also an all-analogue, true-bypass pedal. Its controls let you manage the level, treble, bass and drive of the effect. The analogue tube overdrive provides 33dB of gain, and a flat EQ character. If the amount of gain from the 12AX7 is proving too much, the tube can be substituted for a compatible one such as a 5751 or 12AT7.


Both pedals are hand-built in the USA, and Hagerman describes them as “primarily designed for studio use.” Hagerman also notes that neither pedal is a “clone or copy of a vintage design; it is new from scratch using the best materials and components available, including metal film resistors and polypropylene capacitors.” The modern approach has not introduced much complexity, but these pedals could be the no-frill units your studio setup needs.

The overdrive lists for $279, while the boost lists for 269. Find out more at hagamps.com.
