Sounds Characteristics 

The SELECT 300B captures the heart of what makes the 300B tube legendary, with lush mids, graceful highs, and a coherent, musical bass foundation.

• The bass is controlled and cohesive, with moderate extension and just the right amount of body. Ideal for genres like acoustic, jazz, and classical.
• The midrange is where the SELECT 300B truly excels. Rich, full-bodied tonal character with a touch of warmth. Vocals are especially well rendered, from baritone to soprano.
• The treble delivers the characteristic smoothness of the 300B, with layered extension and a natural sense of sparkle. A soft warmth in the upper register gives strings and female vocals a refined presence.
