Using long cable runs? Use the Lehle Sunday Driver II buffer and preamp pedal to maintain your signal. Your sound will be livelier, fuller, and more dynamic. Two operating modes give you two options for maximizing your guitar tone. In "D" mode, your guitar signal is boosted at the same input impedance of a guitar amp — that means it makes up for the losses caused by a long cable run or a big pedalboard, leaving you with big fat guitar tone full of dynamics. In "S" mode, the Sunday Driver II multiplies the input impedance by five, bringing out subtle nuances in your sound while adding undeniable warmth. And like all Lehle products, the Sunday Driver II improves your guitar tone without adding noise or compromising your expressive range.
