After doing a bunch of research, I'm buying a used H&K bass base 600 from a guy on bassgear.com. All the reviews have been great and the harmony-central ratings are almost straight 10's across the board. Anyone have one of these heads and want to share your thoughts? I'd appreciate it alot. Anything to look out for? Advice on settings? Whatever you want to share, I'd love to hear. I'm just totally in the dark about these heads and this is my first venture away from the "ampeg sound". Also, does anyone know where I can get the footpedal for this? I've been searching to no avail. Thanks!
