Although among us, we have yet to test these out. These capsules obviously have to be phantom powered or plugin powered ( Here is an example of such setup on Wildlife Sound ) – if you don’t have a mixer with phantom power.
The main idea is to use one of these capsules to mount directly onto the top plate of an instrument, in this case Gervais’s Banjo, and here this tiny creature really comes alive. These beautiful little omnidirectional electret condensers have brilliant flat frequency response, cheap as chips, and their tiny size factor means you can make them fit virtually anywhere. The popular Panasonic WM-61A capsules have been very well known all over the internet, and you don’t have to dig deep to find out why.This would provide an extra 6dB of gain, and among other benefits this can be used as a ‘differential’ setup as described here The two Piezo Discs must be wired in the same polarity (to avoid phase cancellation). One is placed under the bridge and another is placed over the bridge. When designing a pickup system for a stringed and bridged instrument, use two Piezo discs instead of one.To summarise, here are some tips and the most discussed points of the evening: Gervais has been repairing amplifiers, fixing instruments and installing pickups for over 20 years. This meetup, we had the pleasure of meeting Gervais Currie an instrument repair expert at Portobello Music. In this one, we’ve have somehow managed to create an ideal environment for experimentation and true self-expression. Unpredictability has always been a thrilling aspect of our meetups, as the tone of the meeting widely varies between one to another. It was truly surreal, and rather entertaining to witness. Suddenly, each corner of the London Hackspace Classroom was filled with the echoing sound waves of mbira, bowls, and the percussive rhythms of the tables and metal bits.
People entered the classroom, and while waiting, spontaneously picked up the objects we’ve laid on the table, and started playing them.
