Substance and style, in one glorious THD package that sits comfortably on your 2x12” cabinet.
Dual bias controls let you complete most tube swaps in less than a minute.
This is the THD Head Box with a
Flexi-50 installed in it. It is the same Flexi-50 THD always made, but it’s now available in a more traditional head
look. The vinyl-covered Baltic birch ply cabinet gives a classic look to the award winning Flexi-50 and provides superior
protection for the knobs and switches, both front and back. This head version is designed to fit perfectly on top of THD’s
popular 2x12" speaker cabinet, but will be equally at home on any of the popular 2x12" or 4x12" cabinets on the market.
Flexi-50
50W/20W Class AB Amplifier Head
The precision, hand-built, single-channel THD Flexi-50 50W/20W Class AB Amplifier Head can operate loaded with almost any
preamp and power tubes in any combination. It's the only amplifier you need to own. Whether you strive for English overdrive,
California clean, or Texas punch, this master-class head can deliver it. It also boasts a heady 50W Class-AB operation, footswitchable
overdrive/boost, and footswitchable master volume control. Its consistently overbuilt and pristine circuitry ensures dramatic
touch sensitivity even at the highest overdrive settings. Its incredible flexibility (the reason it's named Flexi-50) delivers
all the sounds and tones you could possibly desire, from vintage purr to modern, high-gain roar.
It has a Lo/Hi input
switch; Volume, Treble, Middle, Bass, Master, and Cut knobs; Boost section with separate Gain and Tone knobs, and a wattage
select switch (50W/20W).
