i'm not sure how many people are on here yet, but here goes. I own a SDII 30 and I can honestly say it is one of the best amps i have ever played or owned. I tend to be all over the place musically and this amp has yet to let me down when i'm trying to dial in a new tone i'm hearing in my head. i sold a thd flexi 50 to get it because the flexi just didn't have enough gain for me and seemed a bit too bright. before that i had a soldano astroverb that was killer but lacked clean headroom, second channel, and effects loop. the only thing i wish the budda had was reverb. the lead channel volume drop can be a drag sometimes too, but the way i've got it set up currently makes it a non issue.

there is a very simple mod that can even up the channels if you are wanting to be able to lean on the clean side some and have the gain side louder...

how hard is it to do?

    Have you tried using any reverb through the effects loop?

   I've heard that the Electro-Harmonix Holy Grail is really good, for a spring reverb type of sound.

   I'd also try an Echo. I find that an Echo can give you the "air" around the notes, similar to what Reverb does. But, it doesn't get as "mushy" and lost in the mix. A good analog delay should do the trick, also. If you want to try a really good, (and REALLY inexpensive!) Echo, there's one from Danelectro that costs $15.00 to $20.00. And it sounds pretty good, too!
