Yeah, I've been having a similar issue with my Bass Fuzz Deluxe too. I love the sound, but it's definitely lost in the mix a bit, and I've been trying to stack it. Greg, I know you have a VERY similar setup to mine (GK 1001RB, NEO 410 and B3K and MXR Fuzz Deluxe) so if you find any good stacking options, let me know! I'll do likewise! Thus far, I'm liking my B3K set as more of a slight tube OD, then into my GK Diesel Dawg for some real heaviness when necessary, and finally into the Bass Fuzz Deluxe when I'm feeling it. The B3K and Fuzz Deluxe sound great together without the Dawg, as well. Just my rig at the moment, so feel free to chime in with your settings!
