I just got a Fender Deluxe Reverb II. It sounds glorious, and is in top condition, but is very attack-y. It has a C10Q speaker in it, which I would like to change for an alnico (or possibly 2x10 alnicos - but that's another thread) in order to mellow it out a bit. But I do miss the rectifier sag of the SRRI I had a while ago. I am wondering, then, how difficult/easy it would be to mod the Deluxe Reverb II to valve rectification. And also, of course, how expensive. The perfect thing for me would be to have switchable SS/valve rectification as sometimes the very crisp cleans the amp produces with the SS rectifier are very welcome, though I'm not sure if this is even possible (I am a valve amp novice). So, what do you more knowledgeable people think?
