Wireless classical guitar sound

In preparation for my concerts I developed a wireless transducer system for classical guitar that can replace microphone and eliminate feedback loop, allowing for higher volume gains.

The usb-rechargeable prototype system costs less than $100 and works nicely with my rechargeable 40W guitar amp, allowing me to play classical guitar with amplification without microphone and without access to a power point.

The sound sensor attaches to the soundboard with a removable double-side tape. The 2.4GHz WiFi transmitter is attached to guitar leg support using a velcra strip.

By choosing where to place the sound sensor on the soundboard I can optimize the amplified sound.

Transmitter offers 3 basic functions: on/off, +volume and -volume, which is sufficient for most situations.

The system works well and now I can move this wireless sound system from one guitar to the other depending on a gig task at hand.
