About a year ago I won a Hartke A100 in a contest. Nice prize but in the year that I have had it I hate the way it sounds. The aluminum cone is 15" and to my ears sounds too metallic. Is it just me or have others had this experience? Could it just be my attack? I was really excited when I won this and in fact I sold my practice amp because this fills the need for practice and small venues. But the sound drives me nuts and makes practice excruciating to my ears. No matter how I adjust the EQ I am just not unhappy. Someone help me please.
