2-Channel 800-Watt Bass Amp Head

DUAL800 lightweight 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 Preamp Channels For Two Instruments/Dual Pickups

DUAL800 amp head 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 Direct Box 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.

    Fast delivery!!! Very good amp!!

    I have been playing bass longer that I care to remember. In that time I have owned literally just about every bass amp out there. Some very good ones and some not so good, so I know what I’m talking about. I have had this GR Bass Dual 800 for just over two weeks now and have put it through its paces. Without a doubt I can truly say this is the best bass amp I have ever owned to date. When they say Pure Tone, they are not kidding. If you just want to hear the true sound of your bass without colorization, this is the amp for you. If you like to tweak the EQ, then it is all there and then some. It has a great built in tuner that can even handle a six string. With an aux in, two separate channels (mixable) and many other great features, I’ll be using this amp for everything. It’s got it all, heck you can even charge your phone and Dave is a great guy to help you out with your purchase or any other bass related questions.
