KLdguitar Guitar mate Buffer is a complete kit containing all necessary parts and materials to convert virtually any electric guitar or bass to an "buffer" system. A typical installation requires just six soldered connections to complete. All the electronic circuitry is contained in a single compact (40mm x 22.5mm x 15mm) module.
The Buffer is based on a IC circuit using a JFET input stage to give a smooth "tube-like" sound and to provide a high impedance to buffer the instruments pickups, increasing sustain and high frequencies. It help you connect your guitar or bass with longer cable, a lot of pedals with true bypass, Some pedals have low input impedance such as fuzz faces.
