To each their own but that order seems wild to me lol. Pickup placement is certainly has an effect and is an ingredient, but the difference between slanting the pickup half an inch on the thumb, although it softens the top end a bit, is not signficant especially with all the other factors affecting your signal running through your patch cord on an electric instrument. Yes... if you put a pickup bumped directly by the fretboard and neck its going to sound muddier than if you have one bumped up against the bridge however those are the two extremes that are part one of the equation, but the magnet type, pole peices, type (single or humbucker ect) - especially when thrown through an active preamp that completely modifies and shapes the signal on an electric instrument... most things revolving around placement are easily compensated for or made variable, so agree to disagree lol.
The most surprising to me is the bridge being third (above body wood) and the pre-amp being last when its factually the thing shaping the signal the most aside from the hands hitting the strings. Like if you are under the impression that bridge is that big of a factor i assume you think thats beause you beleive it has a singificant effect the sustain of the the string vibation / resonance of the vibrating string... but then wouldnt the wood be more important in that argument? I feel like you would be hard pressed to listen to 5 audio clips with a jazzbass with 5 different bridges and order them from high mass to a fender peice of bent metal, let alone the fact people buy customshop basses with a bent peice of steel still.
Anyways kinda getting off topic here, the great tonewood / tone debate continues on!
A Warwick (owned several) retains the signature regardless of the preamp engaged or not, even when entirely removed. The passive (silver) mec still carry some of character ( I’ve used them in a jazz bass build) the golds are active pickups. The preamp from MEC is my least favorite part of the stock offerings.
I’ve had bubinga, boire, ovangkol, maple, ash, carolena, bodied wicks with Wenge, maple, and ebony fretboards. Maple, wenge, and ovangkol shafts.
I’ve had neck through multilam necks.
Streamer, dolphin, thumb, corvette, FNA.( which had seymour Duncan pre, factory )
Double buck, single, dual J.
4 and 5 string.
A couple with bartolini (factory)
only one (90 streamer standard) did not have the 2 piece bridge.
all with the 2 piece ( unique design with a big block of brass beneath the saddle block, and another block as the tail stop) have a noticeable attack envelope that differs, not the sustain so much. The contribution of the bridge carries through regardless of the woods employed.
the pickup location, combined with the pickups tone is a major component.
like all else, it’s a recipe and open to personal interpretation
