Other interfaces available on the system is also functioning as it should and can set values that affect the processing of voice. It was also found that the true bypass pedal interface can change the path of the guitar input to be routed directly to the output. The test results showed that the Arduino can be used as a controller of guitar sound processing with two inputs and outputs. In the testing phase used 3 kinds of testing, those are hardware testing, test using the software, and testing using respondents.

Steps being taken begins with identifying needs and then proceed with the process of designing both the hardware and software. This study uses the waterfall method of development. So the goal is achieved from this study was to test the Arduino as a controller device that is used in the effect processing. Devices Arduino controller board is present as a central processing for a variety of processing requirements, one of which is processing the sound. The guitar has become common entertainment show at the moment.
