I'm looking for a set of humbucker for a guitar I'm building, however, I know very little about picking a good set. The guitar will mainly be in drop B or C standard, will this effect the tone of the pickup from when I play the guitars in the guitar shop? THey mill most likely be passive pickups if it's relevant
yes of course tuning down means you'll be using heavier strings, and you need to watch put for pickups with a loose or overbearing bass response - they can lead to muddiness when using drop B. Go for ceramic or alnico 8 magnet based pickups, with a strong treble bite, and tight bass, like - dimarzio d activators/drop sonic or crunchlab or Duncan distortions/full shred. Also check out Bareknuckle pickups - a lot of their ceramic mag pickups excel in lower tunings
