LABOGA – The Beast 30 Plus

TECHNICAL HINTS, PROPER USAGE

Do not use the amplifier, before connecting it to the correct cabinet, or using built-in fake 
load (

Speaker Off 

mode at the back panel).

After switching 

Power On

, wait about 30-60 seconds on 

Standby 

(“0”) until tubes get heated. 

When turning the amplifier off, first switch to Standby and wait about 5 seconds. 

Switch the amplifier off before any cable change, except guitar cable.

Use the 15W mode when playing at low volumes or using only headphones to keep the amp 
cool.

In order to ensure proper air circulation, do not block back side of the amplifier or any of the 
ventilation openings.

In case of any objects or liquid access inside the amplifier, urgently switch the apparatus off 
and unplug the power supply cord.

Protect the amplifier from any strikes.

Before transporting, wait about 10 minutes for the tubes to cool down.

Always use a dry or slightly wet cloth to wipe all dust. Never use solvents to clean.

Use additional devices and accessories according to producer’s recommendations.

During storms, or when left unused for a long period of time, power supply cord should be 

unplugged from the outlet.

Crossed-out wheeled bin symbol implies that in EU countries, after use, product must be 
discarded separately in a special, adjusted place. It concerns both the apparatus itself as 

well as other accessories bearing this symbol. Do not discard such products together with 
unsorted communal wastes.

In EU countries there are special systems of collecting used electrical products. Transporting used, 
electrical products in certain, adjusted places, prevents their being harmful to the environment and 

people’s health.
