Im new to metal so, about a year ago, I posted a thread about finding the best bass for metal for a recording project. Coming from a background of funk and dance music, I had been used to playing music where there was a thinner ambience (keys, clean guitar, horn stabs) to make the bass cut. With metal, there is a solid wall of guitar sound and I found out by trial and error just how much the bass tone can influence that wall of guitars......To summarize: Some basses sounded great by themselves but really colored the guitars too much (Peavey T-40), other basses colored them minimally and were acceptable while also punching through the mix (Fender Jazz) but the winner was my G&L ASAT (L2K with tele body) in its best "Stingray mode" (Pickups in parallel mode, Active + Boost but toned down, both pickups on....not exactly a Ray but shares a LOT of the characteristics). It won because it was able to be transparent enough to not affect the guitars and can still be set to punch through the mix. It was truly eye-opening and I realized why so many metal bands use G&Ls and Ernie Balls...Since then, I have bought a Stingray HH for my metal projects.
So Im going to say either an Ernie Ball (Stingray, Stingray HH, Bongo, etc) or G&L L2K from personal experience.......From not personal experience and just watching YTs and seeing folks, Dingwalls are probably in there too but I cant get next to tthe whole fanned fret thing
