The B60 is a step up to a 12” high performance speaker, with high and low inputs, level, gain and contour controls. Other features include: 3 band EQ, presence control, ext. speaker output, headphone jack and a limiter. This is a versatile amp. The re-vamped EQ section with shelving EQ on both the bottom and top and a split mid-range parametric EQ for low mids/high mids allows for exceptional frequency curve shaping. A 12” Fane heavy duty loudspeaker gives this amplifier some serious power and tone.
