I only used the OD channel on about 5 songs, and yes , it was good n gritty... crunchy. . Nicely overdriven. And yes I did footswitch between the 2 channels on a couple songs.
This was just the one gig's settings. For a hard rock band.
I'll often have the blend off & keep the drive outta the 2nd channel completely.
Note the bump in the low mids - I find this helps give me the cut thru and punch in the drive tone that I need.
(Oh and that 2nd pic.. it ain't really all packed up, just there's they dbl Mono gig bag with my gig basses [literally] in this case -- a US Fender Jag & Squier VM P5 - and the Bassman Pro Neo 115 in its cover, the SB300 has his cover removed 4 the pic
