...sometimes. It worked last night. It was the blues jam, and I'm in the house band. I have always struggled with that room, being that it is boomy and echoy (how do ya spell that, lol?). It's a medium-size place with no acoustic tiles and no carpet, brick walls. But there are some rugs hanging, which helps, but I hate that they are also behind my amp (rear ports). I dunno if that makes any difference, though. Equipment: '87 Jazz Bass Special with flats through my Markbass Little Mark III and dual Traveler 151P cabs. See, the LMIII's low knob is centered at 40Hz. Too low, IMO. Then, the low mid knob is centered at 360Hz, higher than what I want to tweak, often. I left the VPF filter off to avoid the dreaded smiley face eq, and used the VLE mostly with the eq knobs neutral---except this time I set the low knob at 10:30. Whoa, what a difference! I had played several tunes with it at noon, but kept sounding too boomy. Now, I don't know what other frequency comes to the front with the 40Hz backed off. I read where someone said that doing that plus boosting the low mid knob a hair can maybe get me to the frequencies I usually like to mess with on a graphic eq, stuff like 100-150Hz. They may be right. I don't mean for this to be all about Markbass, though. My point in posting is for others to hear about this technique. When it seems like you can never get your tone right in a room it just might be the case that lowering your lowest lows might be the cure, even if it seems counterintuitive. I've done it before, but last night really stood out for how much effect I got from it. I got to step offstage for a bit while another bass player played my bass and rig. Man o man, that thing really sounded good, and it STILL had lots of bottom, only the bottom seemed tighter (who says Markbass cabs don't have bottom?). I was really impressed with how good of a tone was coming out. Last week I had played the ole Ampeg V4 and 810 there, but I gotta admit I like what my Markbass rig did even better Sorry, but it's true, IMO. I'm still thinking about it this morning (at work now with my eyes drooping, lol). So, next time you're in a boomy room try rolling those lows down some and just see what ya get. It might work. Thanks for reading, ya'll.
