The Laney P20 generates 15 watts RMS output and houses an 8" Custom Driver. Round the back of the unit the rear panel houses an extension speaker out, a phones / record out socket and the FS2 and FS1 footswitch sockets to enable foot switching of the user channels. The top of the unit is finished off with a very stylish moulded handle. The P20 can be used in one of two modes - HERO & LIVE. HERO mode comes pre-loaded with 11 inspirational guitar tones from "Clean to Extreme" which take their inspiration from the different amp and effects combinations used on classic guitar recordings.

Simply select the AMP mode you want, adjust the controls to suit and the add the effects you want and then store the end result to one of the four user channels, simply holding the desired channel button for 2 seconds.
