The tube screamer is always a great tool to "clean up" bassy hi gain sounds like from a recto. I removes some of the low end and provides some mid boost which can result in more tranparent sound, especially when doing detuned stuff. Check out Ola´s Triple Recto, he also used it there.
However i sometimes find its impact on the tone a little bit too much for me and i was looking for a more moderate version with more control.
I think that the studio eq can really be great if you put it in a stomp slot before the amp section. To get started i made a preset with uses mid1 band with a frequency of 1450 Hz, Q of 0.7 and the gain to your liking, just how intense you want the effekt to be. You could also roll some bass if you want.
Just push it a few dBs so make an amp sing.
The pure boost or the lead boost??...or do you have already the new FW with morph capacity..?
