I’m looking for anyone who has experience building certain mods into the Emerald Ring circuit. Primarily a Gain control, Null control and possibly a Volume control. I be interested in what component values were used, etc. I have a couple of schematics with different values.
For example: Gain controls off the emitter leg of Q1 using a B10K pot with 10uF cap to ground off Lug 2 vs. B5K pot with 100uF cap to ground off Lug 2
Null control using a B25K pot vs. a B250K pot off the Emitter of Q2 going to the 47nF cap
And A50K vs A100K Volume/Level pots at the output
I got the idea for this from the GFR Inside Looking Out solo where there appear to be fuzzed out octave up notes similar to a ring modulator effect. This occurs about 4:30 in the 1969 Live Recording version.
I thought it might be good to stack the Tone Messer fuzz that I plan to build with the Emerald Ringer to get this effect.
