PEDAL PREAMP The Guitar Butler is a dual guitar preamp designed to deliver exceptional service to the entire signal chain. Perfect for guitarists looking to get their preamp sounds out of the pedalboard, directly into a power amp/speaker cabinet combination, or directly into a PA system. It has 2 channels: A classic-sounding clean channel that makes it easy to put the pedals in front, while the wide range of EQ allows precise control, adding warmth to humbucking pickups and brightness to single-coil pickups. The drive channel with its JFET circuitry behaves like a tube amp, resulting in a classic overdrive channel without digital distortion. The buffered effects loop lets you add effects such as modulation, delay, and reverb after the preamp. Clean channel: Gain and 3-band EQ. Drive Channel: Gain, 3 Band EQ, Volume 1, Volume 2 and Presence Controls. ¼'' jack input. Buffered effects loof. Amp Output: ¼'' Jack without Cab Sim. Balanced XLR output with Cab Sim. Earth selector. Power: 18V (power supply included). Dimensions: 17.7 x 6.7 x 15.5 cm. Weight: 1.3 Kg.
