A few pics of my most recent finished work. Fretless 4 Finn prototype. First bass to have a piezo bridge feeding one of the lowpass filters in the pre-amp and the RFB feeding the other. This allows full EQ of the piezo and blending of the piezo and magnetic pickup. Recurve 4 with Black Limba body Splated Beech top and an acrylic impregnated finger board.
