Hear This!
The Loudbox amplifier is capable of cleanly reproducing
the sound of your instrument at very high volume levels.
Prolonged repeated exposure to high sound pressure
levels (SPLs) without protection can cause permanent
hearing loss. OSHA has set guidelines and specified
permissible sound exposure limits for those who work in
high SPL environments.
