Add level control to Arion SCH-1 Chorus pedal

[dwitgrafiks1pedalguy]

Hello:
  I recently purchased an Arion Stereo Chorus SCH-1 pedal.  I would like to add an attenuator to reduce the output level of the pedal, slightly, or an internal resistor, if that would be sufficient.  The pedal is considerably louder when engaged than when bypassed, and it has no level control.
Thanks

Hi & Welcome..

Without dealing with gain stages etc, the easiest way is to either replace R38 & R39 with 50-100k dual gang pot (wired as variable resistor) or (better) replace R40 & R41 with 100k dual gang pot..
(outputs from wipers, of course..)

Perfect!! I will order the 100k potentiometer right away.
Thanks for your knowledge and help.
