Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Sessionette 75 (SG75) is a two-channel solid-state combo built by Session in Basingstoke from April 1981 to October 1988, and one of the first amps with two independently preset, footswitched channels. The overdrive channel has gain, a post-distortion filter control and an EQ bypass; both share a passive three-band EQ and Accutronics reverb, driving about 75 watts into a Celestion G12K. A Mark II version was on sale by 1985.
