So, I have been entertaining the thought of replacing my Ampeg BA115 with something more "modern sounding". I have tried a few amps at my local Sam Ash but cannot really decide. I know there are many threads on these two brands, but I would like to know anyone's opinion/experience on these 3 models: Hartke HyDrive 115 GK MB115 GK MB210 I like how my MIA Jazz sounds through all of them, but still a bit indifferent. I really like the Hartke, but have some concerns over reliability. Also, I have always played through 15s, but the MB210 sounded quite good and with the option of adding an extension cab, this has my attention also. Comment as you see fit, please. Thanks in advance.
