Beyond the brand chosen for the tubes, a decisive aspect is the choice of grade.
Indeed, we classify lamps into 3 categories:
Low grade: These tubes saturate quickly and attack gently. Particularly suitable for blues or rock.
The average grade: These tubes have a clear attack and a good dynamic. Versatile, they are suitable for all styles of play.
High grade: Tubes provide the least distortion at high power. A better dynamics with the counterpart of a slightly more aggressive sound, often used for heavy metal and some bass amps. Particular attention must be paid to the settings for these tubes.
