ROWIN NANO Series LN-328 Tube Drive OVERDRIVE Tiny effect pedal - big sound! A very versatile overdrive pedal offering sounds of the classic Tube Screamer. Two modes, BOOST: High peak mode, boost up the bottom end, when increasing distortion by Drive knob, you will get more volume and a slight increase in high-mid range (around 3.5KHz). NORMAL: Low peak mode, color up extreme little to the original sound, very nice for clean boosting. The best thing about this boutique pedal is that unlike any similar counterparts, the Rowin LN-328 Tube Drive comes at a surprisingly affordable cost so that any guitarist can take advantage of its amazing sound.
