The Boogie Board

Hello there,

this is Joachim from Germany. I was wondering if I could do a BIAS mod to get the Opportunity of swapping between 6L6 and 6V6 Tubes. The idea is to tame the loudness of this little monster.I don't use the drive channel - just the "clean" channel, slightly broke up (Gain set at about 6), with a Maxon TS9, a Boss Blues Driver and a TC Spark Booster in front.
Does the BIAS mod to having the chance to swap the Power-Tubes make any sense to you guys?

Any comments are highly appreciated!

Greetings, Joachim
