Well here’s what happened…
Went to the local GC and of course the sales boy was new and had no idea what I was asking for. :rolleyes: But after a bit of looking around, he found an FD2 and we plugged it in along with a few other OD’s: A Tubescreamer, A Delta Labs Tube Drive, a BBE Green something or other (big ugly green pedal), my Marshall Bluesbreaker II, and also the FD2’s little brother, the OCD (Obsessive Compulsive Drive).
Now I haven’t used a OD pedal for anything but a relatively clean boost for solo’s since I was in high school. I just prefer tube driven distortion I get from my amps and I never thought a pedal could match the tone of hot tubes. I was wrong.
I tried the FD2 first - it’s a great sounding pedal. Nice, warm tubey type of distortion and the MOSFET settings weren’t too noisy like most MOSFET pedals tend to be. I new it was going to be good, but not THIS good. Really responsive and just… aaaahhh 
Next was the Tubescreamer. I knew what these sounded like, but I wanted to have one for a/b comparison with the FD2. The FD2 blew it out of the water IMO.
The Delta Labs pedal really sucked. No character whatsoever and just lifeless. It seemed like when I hit an E chord and let it ring, the tone dropped off super quick. Not enough compression in the circuit, I guess.
The BBE pedal wasn’t much better. Truly sucky tone. It was like a kids toy compared to the FD2.
Next came the Fulltone OCD. I suspected it would sound a lot like the FD2, and it does - almost exactly, actually - it just doesn’t have the MOSFET circuit and the boost channel that the FD2 has. It did have a slightly better tone than the FD2 IMO. It sounded a little fuller, with a little more on the bass frequencies, which I liked.
So it came down to the FD2 or the OCD. The FD2 had the boost channel, but you can only use it when the OD is on, so I wouldn’t be able to boost my clean sound from my amp with it. This and the better tone of the OCD was the deciding factor so I went with the OCD.
For the boost, I went with a separate pedal - the Boss GE-7 Equalizer. A nice transparent EQ pedal when all the sliders are in the neutral position. However, it has a +15 db boost slider as well so it gives me enough juice to get over the top for solos - clean and dirty. 
I’m pretty happy now. I’ve being playing with the OCD all afternoon. I can’t believe I’m getting this kind of overdrive from a pedal. It’s amazing…

So basically, I set up the clean channel on my Egnater with the gain up to right where it starts to break up. Then I use the OCD for a distortion “channel” and the boost gives me volume whether the OCD’s on or not. Best of both worlds…
