Description
The THD Flexi-50 Rack-mounted Guitar Amp Head is a precision hand-built 50-watt Class-AB amplifier with foot-switchable overdrive/boost, foot-switchable master volume control and the ability to use almost any preamp and power tubes in any combination, including 6L6, EL34, 6V6, 6CA7, 8417, 6550, KT66, KT77, KT88, KT90, KT100, EL84 (with Yellow Jacket adaptor), 6K6, 6F6, 12AX7, 12AY7, 12AU7, 12AT7, 12AZ7, 12DW7, 12BH7, ECC83, ECC82, ECC81 and many more, giving the user a huge pallet of available sounds simply by changing tubes. The amplifier has a fat, clear, full clean sound reminiscent of late 1950s to early 1960s American combos, and overdrive to rival the best British heads. Even at the highest overdrive settings, the amp still demonstrates dramatic touch sensitivity, cleaning up very well when the volume on the guitar is reduced. Additional features include external bias test points and individual bias controls, permitting the user to quickly and accurately set the output tube bias with any digital voltmeter. The dual bias controls permit the user to correctly bias even mismatched tubes, eliminating the need for matched power tubes.What does all of this mean for you, the player? It could very well mean that the search for your sound is finally over. While UniValve and BiValve-30 amplifiers offer the same flexibility and choice of tubes, they do so in a Class-A circuit. While Class-A amplifiers do have a strong following due to their smooth, even character, there are many players who need, or even crave the immediacy, clarity and "punch" of a grid-biased Class-AB amplifier. The 40 year long love affair that guitarists have had with the now almost clich‚ 50 watt rock and roll amplifier head is proof of this.In the Flexi-50, THD has brought together an ideal combination of simplicity and flexibility, hence the name "Flexi-50". Why strive for simplicity? Robust design and construction are among the reasons. Ease of use is another prime reason. Another byproduct of an overly complex amplifier is that it can take a very long time to uncover a sound that really works for you.How is the Flexi-50 different? First off, it is a single-channel amplifier, but one that can be switched and blended among a number of different sounding and different feeling voices. The changes can come from a number of methods including foot-switching a preset boost level with its own, dedicated tone control that allows you to make your boosted sound darker than the clean sound, brighter, or anywhere in between.The unique combination of a touch-sensitive input circuit and the wonderfully active and reactive tone control section make for a front-end that really responds to subtle and not-so-subtle changes in the signal being fed into the amplifier either by the guitar or any effect that may be between the guitar and the amplifier. Back off on the volume control and the amp gets much cleaner without losing the fatness of the full-volume sound.Switch from
