The LG20R is an open back guitar combo loaded with an 8 inch
loudspeaker. It is a retro styled cabinet with the controls on the top
face for ease of use. It has a split channel preamp layout, which gives
you separate clean and drive level controls through a shared master
EQ with bass, mid and treble. It features a headphone socket for
private listening; AUX IN socket should you need to play along to a
CD/MP3 and a headphone socket for some private time without
waking the neighbours. Finally it features a built in reverb with level
control.
An explanation of these features follows on pages 10-11.
