GR Bass DUAL800 2-Channel 800-Watt Bass Amp Head

2 Preamp Channels For Maximum EQ Options

DUAL800 2-channel bass amp head provides a whole new level of user flexibility. Two instruments can be plugged in at the same time with each having its own dedicated preamp channel and EQ. In addition, this bass amp delivers 800-watts of concert level sound in a small package. Also, it has a front panel LED Tuner/VU meter and a headphone output.

Two Basses Or One Bass With Dual Pickup Outputs

DUAL800 provides two completely separate preamp channels each with full identical EQ. So, you can plug in two different instruments, and customize the EQ for each without affecting the other. Another key point is instruments with dual/stereo pickups can have separate EQ processing for each pickup.

2-Channel Bass Amp For Recording & Live

Two XLR DI outputs connect the preamp signal for pro/home recording studio or live gigs. These outputs can be assigned to DUAL mode with each preamp channel having its own dedicated DI output, or to MIXED mode with a single DI output having both preamp channels combined.
