I am looking for a (preferably passive) bass with a growly, deep tone like a Thunderbird, but I am not so much a fan of its body shape or cost. I know that the tone comes from some combination of the mahogany body and neck, and the Gibson humbucker pickups. Are there other types of basses floating around with a similar sound? Or should I get a mahogany body from Warmoth, in which case, are there pickups that anyone can recommend for that type of sound? I know very little about soapbar pickups. Thanks!
