Polybass 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! you gain:

– the Polybass effect
– battery consumption at least 5 times lower
– 6 or 7 low noise discrete preamps on the Polybass
– volume controls for each string
– optional wooDi attack smoothener
– optional 13pin Roland GK output (needs a little work on the plastic)
– optional Roland GK controls (needs drilling)
