bancika said:A) some mesa amps have the EQ circuit without the sliders, like contour control on the express amps.
B) those transistors cost less than 1$ retailedThe most expensive part of the EQ are sliders and inductors. By eliminating sliders they cut the cost roughly to half.
Yeah, not sure if someone already said it, but the Studio Caliber has a fixed tone stack inbetween 2nd and 3rd gain stage on the Lead channel, and I didn't even bother trying to figure out what the transistors set to flat EQ are doing exactly. Right now, I have a temporary toggle switch that true-bypasses that part of the circuit or goes stock. But, I bypassed the recording circuit + speaker mute, and completely changed the voicing of both preamps, adding a bias adjustment pot as well. Sounds hawt!
