Before this head came out my favorite head was the infamous Block Letter 5150. I heard this head paired to a Dr. Z 2x12, and I was in love. For someone who listens to heavy bands, this head was like a dream come true. The both in a 100w and 50w version, each has it's own special place. The 100w version gives you all the tone of a 5150 to fill any venue. The 50w is great for smaller events, as well as recording. Great for getting a massive sound without having to crank the volume to get what you're looking for. I strongly encourage anyone to at least give this head a try.
