The blackheart stuff is fantastic. After owning every model at some point, I would say the bh15 is my favorite. Throw in a set of JJ's and a decent speaker and you have a really solid little amp. There are several mods available, but after I modded my 5-watter, I really didn't think there was a huge difference. The speaker and tube swap are much more noticeable and certainly cheaper and easier.
I'm just two people short of a threesome.
