Re: solid maple wings on Euros... Spector themselves (PJ Rubal iirc) stated the following on talkbass - I don’t have the thread to hand but this can be googled..
1) maple wings on Euro’s were European maple, which isn’t as hard as North American maple - and doesn’t sound the same
2) they specifically designed the Euro ‘sandwich’ in an attempt to get closer to the sound of US spectors
3) the ‘sandwich’ actually costs them more to produce than if they had used solid european maple wings
In practice far more of the tone will be due to the North American maple neck-thru wood blank (same on euros and on US spectors) PLUS the emgs/preamp. Just trying to share some facts.
in any case this looks like a killer bass, with whichever hardware it’s wearing! And like all spectors it should also sound great, regardless of body wings material 👍
