the modules

A list of the modules, as currently envisioned:

* input section: two input jacks, input level (pull bright), 6-pos HPF switch.
* active EQ: treble, mid freq, mid level, bass, LED. (2x)
* type M gain stage: gain (pull colder), bass, mid, treble, level, LED.
* type F+ gain stage: gain (pull 2-stage), bass (pull alt voice), mid (pull raw), treble (pull bright), level, LED.  (2x)
* reverb: 6-pos source switch, L mix, R mix, LED.
* bypass switches: a panel of 6 switches which replicate the footswitch functions.
* master section: NFB in/out, resonance, presence, master volume, mute switch, preamp switch, power amp switch, two power LEDs.

In addition, I have designed two other "horizontal" modules, which can go into the same slots as the gain modules; however, for my own amp, I won't use these:
* 5-band graphic EQ: LRC resonant circuits with tube opamp, center frequencies based on the Mesa Boogie Mark IV.
* dual semi-parametric EQ: similar to the variable mid controls from the four-knob active EQs, possibly with wider frequency range.
