Thanks guys!
No, I don't use a pick. However, I do use a variety of right hand techniques; so that switch you're hearing is a change in technique that produces a significant change in tone and attack. You can kinda see the difference in hand position in the above pictures.
Yes, the Maple S1 is a long scale. And it does have some neck dive; it's not as behaved as I would like. However, it sounds and plays wonderfully. The Maple bass was used on all the demo tracks. The other bass pictured above is a 32, and it does balance better than the 34. The 32 bass is tuned to Eb and is used on a few tunes that would normally be in E, such as Riviera Paradise, because the guitar player is using a Strat tuned down to Eb. The two basses sound very different; besides the scale length, the primary difference is the top and back laminates.
Europa has long been one of my favorites as well and has been on my set list for a while. It's fun to play!
And do let me know when you will be in the area!!
