NAD. My newest GASquisition, a GR Bass AT Cube 500 combo. Loving it so far. Very flexible 4-band EQ. Deep, Bright and Mute switches. Multifunction LEDs (24 or thereabout). And a couple of cool features: 1) a 9 V, 300 mA pedal power outlet, and 2) its internal 12" custom driver is connect to one of the two female Neutrik speakON connectors via a 90° 1/4 TRS plug, allowing you to easily disconnect the internal speaker and drive two external 8-ohm cabs.
My Rumble Studio 40 is sized perfectly, allowing access to the 500's controls.
This review takes a minute or two to get going, but there's some really interesting info about the custom 12" driver and the AeroTech graphite cabinet material.
