This board is good quality and is well labeled. This is easy to build. The three colors are for bass, middle sounds and treble. The meter works with the microphone and does not have a line in.
Super fast delivery given the current COVID-19 pandemic, received within about 2 weeks! Absolutely brilliant kit and super fun to put together. All the values are marked on the pcb so no need for schematic. Works perfectly. Well packaged and as described. Definitely recommend for anyone who enjoys kits.
