THD FLEXI-50

The THD Flexi-50 is a high-quality boutique tube amplifier that stands out for its extreme versatility, sonic transparency, and innovative technology.

An amplifier for all tube lovers
The special feature of the THD Flexi-50 is its variable tube configuration. While most amplifiers are fixed to a specific tube type, the Flexi-50 allows the guitarist to use different tubes such as EL34, 6L6, 6V6 or KT88 without having to make any modifications.

With 50 watts of power and a pure Class A/B circuit design, it offers an enormous range of sounds, from crystal-clear cleans to an organic, harmonically saturated overdrive.

The control is intuitive: In addition to a 3-band equalizer, there is a gain control with a Bright and Fat switch that provides additional tonal flexibility. In addition, the Flexi-50 features a serial and parallel effect loop, making it perfect for use with pedals.

The THD Flexi-50 is one of the best boutique amplifiers for guitarists who require both vintage sounds and modern features. Its excellent build quality, its unparalleled flexibility when switching between tubes, and its direct, vibrant sound make it a top-notch choice for studio, stage, and demanding guitarists.
