Tom writes to let me know about the Shadow Electronics SH Stompin' Bass, a miked up bit of wood for those times when tapping your foot isn't loud enough. It has active electronics and needs a 9v battery to work. Tom is sceptical, saying: "Cheap mic and a bit of wood perhaps? total cost...about a tenner", but Shadow reckon "Made out of chosen rosewood which is often used for high class bass guitars the Stompin’Bass works as a fantastic bass or bass drum accompaniment to your acoustic band." Acoustic?
