Reverb Modification | |
Article from Polyphony, July 1977 | |
I noticed that if R11 was set for Max. Reverb and S1 switched to Out position, the audio signal level dropped considerably. This can be easily corrected by replacing S1 with a SPDT switch and connecting it as shown in the accompanying diagram. When S1 is in the IN position R11 works normally, when switched to OUT, the ground is lifted from R11 rendering it functionless and grounding the R10 - R13 junction thereby killing the reverb effects.
