How did you learn of Nordstrand Pickups? TalkBass, I think.
What do you believe are the most important factors in tone (ie, electronics, woods, touch of the player, etc..)? Assuming you take the player out of the equation, I would say pickups are #1 by a longshot, then strings, then the preamp or other downstream tone shaping as used. Solid body instruments aren’t affected as much by body woods as many people believe (IMO), though the fingerboard wood will have a more perceptible impact.
Who are some of the top players that you have built instruments for that use Nordstrand Pickups in their basses? I hope they don’t mind the name dropping (you did ask!) but we have basses with touring and recording players such as John Taylor, Juan Alderete, Tim Lefebvre, Jesse Keeler, Bryce Soderberg... and also some great solo talents like Remco Hendriks and Andy Irvine who have been a huge part of growing our brand. Every single one of those guys has Nordstrand loaded basses!
Do you play bass or guitar? Bass only, and that is more past tense than present. I’m more of a dabbler now that I am surrounded by basses all the time.
