slap-o-matic was a commission for a two string hybrid between a double
bass and a bass guitar. The slap-o-matic is made largely from spruce
with rosewood fingerboard, bridge, saddle and string anchor points. It
features an inbuilt piezo pickup located under the bridge and has
volume and tone controls and a 1/4" jack output. The instrument is
supported on a slightly modified arm of a snare drum stand (as
specified in the commission!).
