Upgrade board for Yamaha Silent SLG 100…130

we made a huge effort to reproduce the original Yamaha board with the same components so you can replace it without soldering or drilling! this is the simple mono version. there is also one with the Polybass effect.

you gain:

– battery consumption at least 10 times lower
– much better noise
– optional wooDi attack smoothener

sorry the picture show the hex version. the board looks the same but without Polybass board attached
