Warranty: 5 years GR Bass DUAL Amp Manual Customer Reviews 1 review for GR Bass DUAL800 800-Watt Bass Amp Head Rated 5 out of 5 Colin Baxter – April 6, 2021 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.
