This is without a doubt our most sonically powerful head, combining the dynamic Studio Pre with a 500W analog power amp. Features three different types of onboard distortion (two tube, one solid state), fully parametric EQ, high pass filter, compression, separate XLR outputs for clean and amp channels, and more. Take studio-level control to the stage!
