Amplifier for guitar practice

The amplifier described is intended as a practice unit for guitar players. Its power output is not sufficient (in most cases) for use during a (public) performance. In most other respects, it is, however, virtually identical to a standard amplifier, as evinced by its variable clipper, extensive tone control and facilities for connecting various effect units. Moreover, the facility for setting the gain and master volume controls independently offers even more interesting possibilities.
