Difference between Plexizer, and JCM800?

[caspercody]

Has anyone built these two? And is there any difference in sound between them? Are they also similar to the Thor (but with more control over tone)?

Thanks

I'm just guessing, but i think the JCM800 has a little more gain (since it is a 3-stage). i haven't built 'em, but i have 2 soundclips of JCM800, and i have mojo's Plexizer sound clips. The Plexizer is (in design terms) almost the same as ROG's Thunderchief (the one with tonestack) Two gain stages, source follower, tonestack, pseudo "P.I. and Poweramp" .

The JCM800 (by Electric, 'cos Erik's version omits the 2nd stage) has an additional 2nd stage (10k source resistor, just like the real amp) and omits the 680n at the next stage (compare both schematics).



(pssst, ask for soundclips of the JCM800-Emu)

Can you attach the sound clips? I have been looking for some. I built the Thor, which is the updated Thunderchief, and am wondering if this would sound similar to the Plexizer?
