The tonic offers 3 bands of equalisation with a versatile sweep midrange section and fixed two frequency high and low bands. The tonic also has a high pass filter utilizing another real choke. The signal path of the tonic is all True Class A discrete transistor with the output balanced via a Lundahl* LL1517 high spec transformer. The tonic is designed to fit into the popular API* 500 Series modular racks and requires a rack to function
