So, back in April of this year, while auditioning for the band that I am currently playing in my amp crapped out. I had a back up (an old acoustic head) but this was a live on stage audition and I quickly realized it just wouldn't suffice. Determined not to ever let that happen to me again I bought a new HARTKE LH500 the next day. I LOVE this amp. Perfect for what I am doing with room to spare, or can I really spare it? I have come to realize that atop of my Fender HM 215 (4ohm) or my acoustic stack (8-split or 4 ohm combined) it fills the room quickly. I have never had the LH500 past 2 on the volume dial. I know I often tend to worry about things that I shouldn't, but I worry that I may damage the head at constant low volume playing. Do I have anything to worry about. Your input is much valued.
