I MADE PURCHASE #1
First of all, I want to thank everyone! You are all good people. Taking your time to help a stranger out says volumes about this community. I should have joined this forum years ago. The only negative is the amount of GAS you guys have given me!
So, at the repeated advice of "get out there and play as much as you can", I went down to gear row in Hollywood today. I did Guitar Center, Sam Ash, and the Mesa store. Sadly, between those 3 places, they only had a small fraction of the amps mentioned in this thread. I would have loved to play more.
First was Guitar Center. They had class D Markbass, Ampeg, GK (used), Acoustic, and Fender. Played them all, and they all had things I liked, but I wanted to play more.
So, I walked across the street to Sam Ash. For a huge store I was disappoint that all they had in class D was Fender (which I played at GC) and the Tonehammer. The Tonehammer was weird. First I ran it through an Aguilar 4x10 cab, and no matter how I adjusted it, it was distorted. But, it was kind of a weird distortion. The guy at Sam Ash was convinced that the cab had a blown speaker, so we hooked it into another Aguilar 4x10, and it gave the same exact response. No matter how it was adjusted, it was distorted. Then we plugged it into an Aguilar 1x15, and it sounded completely different. It sounded really good through the 1x15, and I was able to dial in a nice clean tone. But, the anomaly in response (relative to the cabinet it was paired with) was deal breaker for me. It was baffling to both me and the Sam Ash salesman that the head responded so differently to the different cabs.
Then from Sam Ash I walked up the block to the Mesa/Boogie store. I played the Mesa D-800, I loved it, and bought it. For $699 and it's tiny footprint, the thing just blew me away. It was my favorite of the day, by far.
My bank account wishes that my class D story would end here, but it won't. I am still dying to play many of the other amps that you guys suggested, and I have a feeling that there will be at least one more class D coming my way. I figure I can buy at least two or three of these for the price of one high end tube amp. I am totally fascinated by what these little heads can pull off. My GAS is raging in the key of class D!
