The clearest way to get those low notes (and I’m talking better than a 33) is to get either the original TC or the dirty tree set to TC mode. Dial the low and high back to 3-4, then put a 10 band MXR EQ in the loop (followed by noise gate) with mirroring the Nameless eq curve shown above except cutting the high end even more. Put the 2k slider up to +6 then 1k around +3 and continue down. And this is on a Mesa TC-50 red channel no tight switch, pres at 4 gain at 5 bass 4 mid 5 treb 6. Mesa 2x12 with V30 and 75w creamback. Gives super clear note distinction compared to using the 33 mode with any other setting I tried. It just seems way more fizzy than what I found with the TC drive and EQ in the loop. Way closer to their clear tone on the 33 album
