The Custom Valve 50BLUE is based off of the already extremely popular Custom Valve 40, which was a past Guitar Player™ Editor's Pick Award Winner.
Real tube overdrive is provided by three premium 12AX7A dual triode preamp tubes while the 50 watts of real tube power is provided by two EL34 power tubes. The internal gadgetry in this channel switching amp provides great flexibility, but makes it very easy to get a great tone. The combination of the tube power and the Celestion™ Vintage 30 speaker can only be described as magical.
But unlike our vintage looking Traynor Custom Valve series which feature black vinyl covering and 5881 tubes, we have added a Blue Nubtex covering, black grille, black logo as well as black plastic corners along with the EL34 power tubes to complete a whole new look and feel that is destined to become a classic. This combined with the Celestion™ Vintage 30 speaker help gives the Custom Valve 50BLUE a rich "boutique" look, sound and feel. The three basic tones (clean, crunch and overdrive) are easily defined. Great tone at low levels can be easily achieved, thanks in part to the addition of a Master volume control not found on the 20 and 40 watt Traynor amps in the Custom Valve series. The voicing of the lead channel has been tweaked to provide a more ominous or darker "British" tone, a natural evolution for an amp powered by EL34 power tubes as this complements the tubes natural tonal characteristics. We challenge you to compare us to the competition. You'll love the tone and instantly recognize the value.
Although signal-to-noise is not normally a specification that is discussed where guitar amplifiers are concerned, the ultra-quiet Custom Valve 50BLUE makes it an issue. Experienced professional users will appreciate the auto-matching tube circuit that maintains bias balance as tubes age ensuring hum free performance. The DC filaments on the preamp tubes all but eliminate hum. Listen carefully. Although the Custom Valve 50BLUE has a tremendous amount of gain it remains virtually hum free.
The rear mounted control panel is easy to access, yet recessed for protection. And the warranty? Yorkville's standard two year (even if you break it!) transferable warranty.* The one that made Traynor famous in the sixties.
* Warranty valid in Canada & United States only.
