I'm sorry my friend, but the HM-2 is shit. I suppose it's theoretically possible for the HM-2 to sound good with the right amp and guitar combo, but I have no idea what that combo could be. Somewhere I have two that were given to me back in the 80s, and they sound so bad I'm not willing to invest the time to mod them so they sound better.
You really need to play with some other pedals; most are better than the HM-2.
