Re: Classic Tube Revealed!! (initial report)
Jim,  
Do you have a schematic specifically of the FX53 or FX52? Either one would be a help. Stuart was kind enough to mail me his, but I'm curious if you have another one or a more complete one.  
I've got two of these screwy pedals now and actually there are three gain regimens as far as I can tell.  
1) at low gain (less then 40%) I think only the diodes in the feedback loop clip. Produces a bass heavy TS type sound. Works great after my Soul Bender  
2) at 40% - 90% the diodes from output to ground start to clip. Produces a heavier clipping sound like a fuzz.  
3) at 90% and higher I have no idea yet what's producing the distorion, but it's insane. I suspect its the diode in the collector load or maybe some sort of CMOS type distortion. I don't really know, but it's crazy.
