Thanks for this, Simeon. I hadn't visited this one in awhile, and it made me redo my primary patch. I was using two Bludo blocks, one for crunch rhythm and one for a thicker lead tone, but I had trouble dialing out some low mid stuff in the rhythm side in particular.
The CA tone immediately got me closer to the thick preamp boost tone that I have on my home brew ODS for leads, although I ended up nowhere near your tone stack settings.
But I also decided to revisit an amp I used to use before the Bludo, the Ford 2. That is now my main crunch rhythm tone...it has girth and midrange clarity, but lacks the issues in the low mids I was having with the Bludo. Using EL-34s and the ECC803S, it cleans up and sits in the mix better for rhythm than does the CA with reduced drive. So thanks for the reminder to explore!
