On another page of the blog I listed several piezo / pickup systems for double bass, which have pros and cons to examine carefully. Here I report only a live test, of our PC-DB low gain version. Giacomo Rossetti plays with piezo Pc-Db mounted on C – Double Face.
This is Negrita live in Che tempo che fa is in effect a test, given that it is one of the first piezo I made, a near prototype. It seems to have gone just fine.
