My HRM Bluesmaster arrived late last week, and I am very sorry I spent the kind of money I did. It sounds awful, and nothing on the Ceriatone website or Nik's advice has helped. The amp has no balls, the OD section does not work, and the volume is at clock radio level. I am using SED 6l6's and EH 12ax7's through a Celestion Century speaker.

Nik has told me I need to bias the tubes,  and I cannot figure out the explanation in the manual. It  is beyond my skills and will not help these issues anyway. I am a guitar player and not a scientist and I have never been more disappointed in a piece of equipment, after reading all the glowing comments. Nik told me to "take it to a tech", which is not what I exepected after spending well over $1000 on this amp. There really ought to be more information on what is required to use one of these before anyone wastes their money again.

Sorry, but I've been playing for three decades and this is the worst.
