I purchased this while on tour in the UK, and it is by far the loudest guitar head I have ever played or heard in my entire life. It truly is the 11th wonder of the world, because this mother****** surely goes to 11! I hope this amp sells to Sunn or a Mötorhead tribute band, or just a sick ass doom rock band that desires so badly to crush people beneath a wave of sound and level every city they play on tour, because this truly is the amp for it." - Frank
