The beauty of the SLO for me is this: At volume, not many amps out there that can give the 3D swirl that it does. Wizards, C+s, SOME vintage Marshalls...some VHT stuff(D60). Turn it up and it gets unique IMO. Clarity is right up there with the best. I too thought it was a little mushy until I put a boost in front...then it sounded like a killer modded 2203, with the biggest power section I'd ever heard. Since then I've discovered Wizards, owned a C+ Coliseum and have my favorite amp, my 72 SuperTremolo so I've discovered more monster power sections but IMO the SLO deserves the accolades. It's easily a top 10, maybe top 5 amp for me.
