WEMBLEY is the evolution of the Guru’s legendary SEXIDRIVE circuit, which was lauded for its exceptional dynamics and amp-like response.
Ideal for use as either a signal boost or an overdrive, WEMBLEY ranges from low to mid-level gain while maintaining a pleasant feeling like that of historical amplifiers played at middle-to-high volume.
The primary characteristic that distinguishes WEMBLEY is the faithful saturation tones typical of the most famous tube amplifiers combine with precise tracking of input signal dynamics.
The 12AU7 tube is used as an input and output buffer in order to offer a better match with the guitar impedances and enrich the sound with harmonics. Thanks to the clean signal of the valve, WEMBLEY offers the possibility of obtaining high gain with low background noise.
ATTENTION! The peak current of the tube in the preheating can exceed 1A (1000mA).
The TIMELESS SERIES is equipped with an internal voltage double circuit. For this reason it’s necessary to use a stabilized power supply capable of guaranteeing a maximum working voltage of 12VDC with 500mA continuous.
We recommend waiting a few seconds at power on before playing to achieve optimal tube pre-heating. This time is also required to discharge the output capacitor and activate the true bypass anti-bump.
