I bought one after giving it a serious workout in the store and comparing it to the smaller versions. $499 new, the Small Block 115 is proving to be a killer little amp. Super light and has a nicer tone to my ears then the GK MB115 despite it being extremely similar. Its lighter then the GK as well but seems to have a better balanced tone. The tweeter sounds much less harsh then the GK which was a really nice touch.
I liked the 112 and 110 versions as well but with only $50 difference between each model, the 115 just seemed to be the most usable for the most applications. 200 watts is just right for a single 115 in a smaller box like this. The 112 was tighter and punchier but could not put out the low end or have the same room filling booty as the 115. Did I mention this amp is light! Feels like an empty can when you pick it up.
