let's just talk about arranging patch, no more talk about comparing zoom b3n to everything else.
what about the best sounding amp+cab sim combo?
if you're looking for straight, simple amp/preamp and cab sim sounds, then it's self-explanatory and straightforward. For example, I use the SVT amp followed by the SVT cab. I may or may not engage the LMT 76 in front of the SVT. If you like SWR or Acoustic or Trace Elliot, just do the same with those amp & cab models, whichever you prefer.
I've just posted settings above for a fairly grindy, 90's grunge "TOOL bass" type of sound using the LMT76, Dark OD, and SVT. What sort of sounds do YOU like? Ultra-Clean? Vintage? Classic Metal? Modern Metal? There is no "best" combination universally for bassists, but only "best" according to what you prefer.
As we've seen with most mulit-fx modelers, factory presets and presets created by users don't always yield a good result for others. It's a crapshoot and too many factors go into why a random preset may or may not work for someone. My settings work for me, my bass, my playing style, my preferences tonally, and also very importantly, how they translate in my live gigging situation (rock/hard rock/metal). I've found that "sweet sounding" presets that sound great at low volume playing at home just do NOT translate well to the stage...again, for ME. YMMV.
