With a pedal, you can slam those input 12AX7s with a higher signal, pushing it into creamy overdrive. If you look at a Jubilee, a JMP-1 or the JCM 800 2205/2210, the first thing you hit on the input jack is a tube based input gain stage.
Some of the JCM900 amps have an IC as the first buffer/gain stage. Putting a pedal in front of an amp like that does not yield the same result as hitting a tube input gain stage. You'll notice that the IC input gain stages sound like crap when you push them.
Moreover, looking at the Jubilee or JMP-1 circuit, the clipping happens before the cathode follower stage. That will change the effect of the solid state clipping and it seems to be a sweet spot for putting diodes in a tube circuit.

Ah, that answered some of my questions. I recently "discovered" the Ibenez Tube Screamer for my DSL 50, and I love how it adds a little to solos to bring them out without destroying the tone or fuzzing out the distrotion level like old pedals from the 70's and 80's used to. I was never a pedal guy at all but my new band "requires" I have a pedal board and I'm now a lot less of a "pure amp tone only" snob. I think tasteful use of effects expands one's playing while I used to think they covered it up.
That being said, I have yet to like anything through the effects loop. I have everything front loaded. Does anyone have any suggestions on which if any effects might work better through the loop? I have a chorus, tube screamer, phase up front, and an EQ I don't use at all because I don't need it with the tube screamer.
