The THD 1×12″ Combo Amp Cab utilizes a tuned port, bass reflex design, employing proprietary techniques to eliminate the standing-waves that haunt typical ported cabinets. The cabinet has been custom-tuned for, and fitted with, a single THD “Vintage 12” speaker, which has a sweet, clear treble and a full, tight bass response.
Like all THD speakers, the “Vintage 12″ is hand-treated and custom-aged to remove the harshness normally associated with new speakers. Tone and technology aside, perhaps the most exciting aspect of this new product is its flexibility. The 1×12″ cabinet’s design allows it to be easily retrofitted with any of THD’s current line of amplifiers, including the UniValve, BiValve-30 and the Flexi-50.
This unit is fitted with a THD UniValve 15 Watt Class A amplifier head with a single output tube that can be switched at will among many octalbased power tubes for different tones without re-biasing the amp. Useable tubes include 6L6, EL34, 6550, KT90, KT88, KT77 and KT66 – easily accessible and interchangeable from the rear of the combo cab.
With the amp in “LoV” setting you can use 6V6 for a total output of 5 watts. A special UniValve Yellow Jacket™ Converter is available allowing the UniValve to use the popular EL84 power tube at a total of 4 watts output power, also in “LoV” setting.
Likewise, the two preamp tubes can be any combination of 12AX7, 12AT7, 12AU7, 12AY7 or 12AZ7.
It has a built-in Hot Plate™ Power Attenuator that allows for full output distortion at almost any volume.
The UniValve delivers tones from smooth and clear to very aggressive overdrive. It is easily capable of driving a 4 x 12 cabinet, yet equally at home in THD’s 1×12” Combo Cab. CEO Andy Marshall minces no words. “It’s one of the best sounding cabinets I’ve ever heard,” he said “It’s every bit as full and tight as our 2×12″ cabinet, but smaller and it records beautifully.”
Switchcraft plugs and Belden wire ensure the combo cabinet will sound great and hold up to even the most rigorous gigging schedule. Another feature unique to the 1×12″ is its included wheels which simply slide into the inset caster plates. Combined with its small size 52 x 58 x 32 cm approx. (20.5″x22.9″x12.5″) the 1×12″ combo is one of the most easily-transported cabinets ever produced by THD.
