Boasting three distinct drive engines right out of the box, the Source Audio L.A. Lady delivers over 50 years of classic fuzz and overdrive tones. The Classic mode gives you the original "Marshall in a box" tone, while the Smooth engine bumps up your midrange and gives you a subtle drive characteristic of modern Texas blues. Crunch mode is a creation courtesy of Source Audio, the company's own take on an overdriven tube amp. And with the Neuro mobile app, you've got an arsenal of drive, distortion, and fuzz tones right at your fingertips.
