Not quite the classic 300B...Yeah, it uses 300B tubes which is pretty cool.
"The JJ 300 BH Triode was specifically developed for this amplifier. Even though it stems from our 300B triode, its characteristics have been altered so the sound is more “guitarlike”. The original 300B triode is very linear and too”Hifi-like” or analytic for this purpose. This is why we researched and developed a Triode electron tube specifically to complement the guitar. The sound we have achieved is different from what is produced with the triode connected pentode commonly used today. The primary aim is a natural sound with ambient triode colouring for distorted sound."
