Nathan, I’m very curious what results you had in swapping out the 12au for the 12ax in the More. I stupidly didn’t tube roll when I had the deep dish. I’ve never really bonded with 12au. 5751 seems to be my fav.
Right here
If you're ever playing around with More and want it to kick harder, you can swap V1 for a 12AX7 (stock is a 12AU7). This takes you from a +24dB max boost to a +33dB max boost and stays clean.
I'll explain why I was playing with this eventually.
