 The LH50’s 50W Class A/B output stage oozes classic, warm tube tones:  The harder you drive it, the better it sounds.  Plus 
with enough gain for contemporary tones, it also has a mean, spiteful side to it as well – making it ideal for any style of playing.  
Built for solid performance on stage, but also equally at home for studio and practice use, plugged into any of the extensive 
range of Laney extension cabinets, the sound will blow you away. 

Your LH50 should give you years of trouble-free amplification, however please take time to read this manual and familiarise 
yourself with the controls as it will allow you to get the best from your amplifier.   We hope you enjoy using your LH50 as 
much as we enjoyed designing and making it.

Best wishes from all at Laney
