Yesterday, all my parts have arrived!! Soldering them one by one took me 3 hours. The PCB turns out perfect as expected and the slide potentiometer is just as smooth. It didn’t work at first… However a reflow saved both my time and money spent lol. Overall it worked great, the baxandall tone control works and it is so fascinating to be building one myself. However at first the tone control didn’t work because of a mismatch of ground plane of the aux input and common ground. So i shorted the aux ground directly to the common ground. I made 3 shorts on the best location for EMI, and the buzzing noise is completely gone (at least to my ears)! The soft underglow also turned out greattt. So ill be vibing and booming with my new audio amplifier 24/7, and as i vibe, ill continue with my github repo. stay tuned then!
