• Provides a solid, powerful low-end response typically associated with much larger combos.
• Remarkably lightweight, ensuring portability without compromising sound quality.

Advanced Power and Pre-Amp Technology

• Features an ultra-high-energy power supply utilizing a Class D power amplifier for high efficiency, resulting in less heat and weight.
• Includes a pure Class-A, ultra-low noise pre-amp, offering a massive dynamic range for optimal tone in any playing situation.

Precision Tone Control
