I bought a CAA OD100SE and plugged it in for the first time last night. I bought it off Ebay and have a few questions as it didn't come with a manual. Can I download one some where or can someone email me one? I found the old OD100 manual on Bradshaw's site, but nothing about the SE. Also, how do I tell if this is the + or not? It has the whoomp switch and is running on 5881's, it also has the feedback and depth knobs on the back. I assume it is a + because of this, but I'm not sure. Before I give my assessment, I have the following heads: Marshall Cameron Aldrich Mod, Engl Powerball, Mesa Triaxis, Carvin Legacy. My assessment after one hour is this. The cleans were very good and close to what I was expecting. I was hoping for a Fender styled clean with a slight break up if needed and that is what I got. It isn't the clean of either the Legacy, which has zero break up but is gorgeous in it's shimmer, or the triaxis solid state with warmth, but somewhere in the middle, a great addition to my collection. I don't use stomp boxes, but wish I had a nice O/D like an Xotic BB to really put it through the paces. Channel 2 wasn't quite what I expected. First, the amps that I own, have a lot of compression, though they don't all sound like it. The gain structure on this head is a lot different. It's full, thick, and clear, while not being compressed (though it sounds more compressed than my Cameron). Meaning, it shows your flaws. I was surprised by the voicing as well. I was expecting a more upper mid range sound (based on the vid clips), but it is closer to my Powerball and Mesa, than the Marshall. With the boost on, it is a raunchy beast, but again, sounds a little more solid state than my Marshall. Where the Powerball is like half way between a Dual Rec and a Marshall, this is like half way between a Powerball and Marshall. Again, the picking is very clear and articulate, even in full chords, which is amazing. The great thing about it is that at very loud volumes, there is no bad feedback, and it just growls. This is amazing for riffs and chord playing. Things I'm still on the fence about are what I previously mentioned. I'm used to amps that allow solos to flow very easily from my fingers. This amp makes you work, which is strange considering the amount of saturation. I was hoping to find a tone similar to Chris Impelletteri's Suhr Marshall (don't laugh, his tone is amazing), which is closer to my Cameron than this amp. I will play around with this more, the amp does sound great for rhythms and clean. My ideal tone would be my Cameron, with a touch more body, less feedback (as it is prone to feedback), and a gorgeous bloom. I guess a more hot rodded brown sound. If I could take the OD100's volume, saturation and note def and combine it with my Cameron's upper mid voicing and growl. If anyone owners out there want to chime in with some tips, manuals, tubes, clean boost suggestions, etc. I would appreciate it. In the mean time, I will keep tweaking.
