The Big Trees (TBTs) is an all valve, Class A amp which doubles as an incredibly versatile preamp, perfectly at home live and in the studio.

The 2.5W amp, built around ECC82 and ECC83 pre-amp and single EL84 output valves, generates harmonic-rich tone, sculpted by its Baxandall-based EQ, and ‘EL84 headroom control’. The Line output (incorporating a valve line driver stage) is either post power- amp stage, or discreet all-valve clean stage for empyreal DI tone.
