INTRODUCTION

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;  CD/Line 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 spring 
line reverb with level control.

An explanation of these features follows on pages 6-8.

BEFORE SWITCHING ON

After unpacking your amplifier check that it is factory fitted with a three pin 'grounded' (or earthed) plug.  Before plugging into the power supply 
ensure you are connecting to a grounded earth outlet.

If you should wish to change the factory fitted plug yourself, ensure that the wiring convention applicable to the country where the amplifier is to be used 
is strictly conformed to.  As an example in the United Kingdom the cable colour code for connections are as follows.

NOTE

This manual has been written for easy access of information.  The front and rear panels are graphically illustrated, with each control and feature 
numbered.  For a description of the function of each control feature, simply check the number with the explanations adjacent to each panel.

Your Laney amplifier has undergone a thorough two stage, pre-delivery inspection, involving actual play testing.

When you first receive your Laney guitar amplifier, follow these simple procedures:

(i) Ensure that the amplifier is the correct voltage for the country it is to be used in.

ii) Connect your instrument with a high quality shielded instrument cable.  You have probably spent 

con

siderable money on your amplifier and 

guitar - don’t use poor quality cable it won’t do your gear justice.

Please retain your original carton and packaging so in the unlikely event that some time in the future your amplifier should require servicing you 
will be able to return it to your dealer securely packed.

Care of your Laney amplifier will prolong it's life.....and yours!

Dear Player,

Thank you very much for purchasing your new Laney product and becoming part of the 
worldwide Laney family. Each and every Laney unit is designed and built with the utmost 
attention to care and detail, so I trust yours will give you many years of enjoyment.

Laney products have a heritage which stretches back to 1967 when I first began building 
valve amplifiers in my parent’s garage. Since then we have moved on from strength to 
strength developing an extensive range of guitar, bass, public address and keyboard 
amplification products along with a list of Laney endorsees that includes some of the 
world’s most famous and respected musicians.  At the same time we believe we have not 
lost sight of the reason Laney was founded in the first place - a dedication to building 
great sounding amplification for working musicians. 

Warm Regards, 

Lyndon Laney   CEO
