There is no need to have a MESA amp biased when MESA tubes are used. Players can count on consistent tone & performance from MESA amps loaded with MESA tubes.
Do I need to bias my amp?
Unless your amp is cathode biased, yes, you need to have it biased when you change tubes and yes, you should periodically have that checked and adjusted as necessary. PAY ATTENTION TO THIS: Most amplifier have lethal voltage inside. So you should NEVER set or adjust bias if you do not know how to do it.
What happens if I dont bias my tube amp?
If you changed to tubes with a lower resistance without biasing the amp you would quickly burn through those tubes and potentially damage the amp and yourself in the process. This is because the amp is still pushing out current at a higher level than the valves are able to take. Until its been correctly re-biased.
Are Mesa Boogie good amps?
Mesa Boogie make only the very best amps in the world. Mesas flagship amp and probably the most versatile of any high-end amp range ever created. Pro guitarists flock to the latest Mark V because it really is the best of the best. Any valve tone can be summoned to your fingertips and toes.
What is amp sag?
Sag refers to the drooping of the power supply voltage in response to large transient signals, which lends a certain dynamic feel to the tube amplifier that is not generally found in solid-state amplifiers.
When should I Retube my amp?
Retubing Guitar Amps. Your amp might need one or more new tubes if its volume, tone, or punch has gotten weaker. You might also need a new tube if you occasionally hear feedback from your amp for no reason. In this case, access the tubes and tap on them one at a time.
Do cathode biased amps need biasing?
Cathode Biased amp do not require biasing to change power tubes. Fixed biased amps require biasing to change power tubes as well as periodic bias checks to ensure they are working properly. Cathode biased amps are less efficient than fixed bias amps. The same amp in fixed bias would be about 40 Watts.
Why do tube amps sound better loud?
Tube amplifiers sound better because of the euphonic distortions they add to the music, as well as plenty of other reasons Ill cover below. The ways that tubes distort when pushed to the edge are much more musical than the artificial sounds that come from transistor amplifiers when overdriven.
Why do tube amps feel different?
Tube amps also tend to have a softer attack and more sustain in the signals ADSR curve, which is why many find them to sound warmer. They can push out a lot of sound in a fairly small format that can cut right through the mix and dont have to be at ear-splitting volumes to get great tones.
