Musical Instrument

The Boost is based on a hybrid circuit using a JFET input stage to give a smooth & quot;tube-like& quot; sound and to provide a high impedance to buffer the instruments pickups, increasing sustain and high frequencies. This is combined with a BJT output buffer to provide a low impedance output, enabling the module to drive long cables, pedal boards etc without the & quot;tone-sucking& quot; effect that usually results.

The module provides 5dB of clean boost - enough to give a healthy overdrive when needed, but not so much that a clean sound is unobtainable. The circuit uses a symmetrical bias, so that plenty of input headroom is available to accommodate high output pickups without clipping - when the input does overdrive, the JFET gives a & quot;musical& quot; soft clipping, similar to that of a traditional valve (tube) stage. The maximum undistorted output is approximately 5v pp. High quality, low noise components are used throughout to ensure the best possible audio quality.

The Boost is ideal for musicians who have home recording setups - there are plenty of great sounding amp simulator plug in available in VST or DX format, however unless you have a good (expensive!) preamp, the basic guitar sound is usually muddy and lacking in sustain. An active instrument can be simply plugged into a line input with no loss of tone
