Features
• Three 12AX7 pre-amp tubes, a 12AU7 Driver (YBA300 only), and 6L6/EL34 power
output tubes (12 on the YBA300 and 4 on the YBA100). That's 300 watts on the
YBA300 (100 watts on the YBA100) of all tube power and tone.
• 3-Band tone controls with frequency selectable Mid control along with Deep, Bright, and
Resonance tone switches.
• True balanced D.I./Line output. Selectable Pre-EQ or Post-EQ and Ground Lift.
• Effects Send and Return jacks (Pre-Amp Out and Power Amp Input). These jacks
provide direct access to the Traynor all-tube bass amplifier's signal chain so you may
slave out, or slave into, another amp; or you can use these jacks as an effects loop (for
professional-grade signal processing equipment).
• Tuner Out jack.
• Individual tube Bias Adjust, Indicator LEDs, and lockout so you will always know the
status of your tubes.
