Here's a question. A couple, actually...
For Luciens; You say you eq that bass so you can hear it. To compensate for your hearing loss. I get it, totally. It's exactly what I do on my gigs, because all the surrounding din of noise on a stage in a club gets in my ears' way of hearing me quickly and well. So, it's a kind of hearing deficiency. So, a question might be, do you think Jaco set out to create his tone that we hear an love, or, was it a result of HIS hearing deficiency, and he made his tone hearable in his way, while you do it your way. And I do it mine. I bet, in a gig context, your tone would not only be great, but also very apparent in a mix. And, totally unique to you. That's a good thing!!
And, two. We all talk bout carrying our tone with us, unable to avoid it. So, are there things you, as a player do, to change the response or your tone that work? Effects, eq settings, certain strings, that actually affect the response you get from your basses and gear. For me? It's overdrive. My technique, my basses, my gear, are just too clear. I feel my mistakes are heard over my successes. Drive blurrs my top end a bit. Not only changing my HiFi rigs and basses top end, blurring it a bit, so I don't hear my mistakes quite as obviously, and, changes my modern, HiFi amps to something a little more LoFi and vintage, something I hear in many of my heroes' tones.
