Caline CP-81: Updated v3.0, PSU Noise Issue Corrected, Volume Fader Mod

This is the summation of 2 months worth of communication with Caline Technologies in China, working with the engineering team and Product Development Specialist contact.
- The PSU white noise hiss has been fixed!
- The volume fader was intentionally designed to limit the output gain. The reasoning from the Caline team was they wanted to prevent the EQ pedal from overdriving preamp sections of amplifiers. Makes perfect sense, but there are times where you would want to do that.
***To change the volume fader operation where it has 12db of true gain, you need to remove R59, a 4.7k ohm resistor, and replace it with a simple jumper wire/solder blob. This effectively removes the series resistance of the potentiometer, allowing the opamp to run 100%. This mod does NOT work for the v2.1 board.
The video camera's mic compensates for the audio signal changes, so the volume difference may not be heard drastically, but to my ears I can confirm the volume fader now operates like the gain fader, exactly how the MXR M108S works!
Thank you to everyone who has followed this project. A great big thank you to the Caline Team in China! Your customer service and support on this is immensely appreciated! I cannot tag their page on here for some reason. Info below.
