Appreciate all the replies so far guys, thank you!
So how would one go about setting the EQ to achieve said sounds?
Might be a little clearer if I just explain what I am after (only just woke up so the old grey matter is pretty useless right now).
My 2 favourite bassists are Jon Stockman from Karnivool and my friend Dave Hollingsworth from Toska/ Dorje. They both predominantly use JJ setups (Stockman with the Warwick Thumb 6 BO, Dave with a custom Chapman model) and active electronics, and they both use those pedals. Dave says that he mostly uses JJ basses as the midrange of them works better for him with the guitars in Toska & Dorje, but from my experiences with jazz basses, they don't have the balls of a P bass, which I do like in single guitar band mixes, but less so in dual guitar mixes (which I think the JJ configuration handles better and it's not so "big" sounding).
I have my eyes on both a Japanese 80's P bass with SD 1/4lbs pickups, and a Squier VM jazz bass (which currently has USA standard Fender pickups but which I may swap out for Nordstrand blades), both with maple fretboards as I've noticed they tend to punch/ bite a little more. I'm basically trying to get close to those sounds without having to shell out for an active bass as I tend to dick about with the knobs too much when I have that option, whereas I'd rather get a sound I like on the B7K Ultra and then stick with that, where I can just focus on playing.
I'm basically trying to decide between which of the basses is most likely to work with the effects I use, as I am in the market for a new bass anyway (I'll later be using reverbs/ delays more and I know the bassist from Mars Volta uses J configurations in his basses because, to his ears, they tend to work better with those pickups rather than Jazz pickups).
I also know that things are largely going to be down to opinion/ tastes/ a countless number of variables, but I'm trying to get an overall view (where possible) to get a better understanding of how all of these things fit together and why.
If you want to check out the sound I currently have, look up ICHIRO - For You on Spotify. Feedback is also very welcome!
