Could anyone be so kind recommending me some of the suitable tubes in the module? I wanna know what kind of tubes setup Ultra, Brown and Top Boost in order to get the best sound possible.
For the Brown, I prefer JJ ECC 83 S 12AX7 tubes, they make the module sound a little grittier with more bite on the midrange. I've tried the Tung Sol as well, they're great for more clarity and a nice clean attack, not as dirty as the JJs.
