I can definitely pick out the differences quite well here. Funny, I can always hear that trademark EMG sound, but the differences are quite big IMO, when it comes to the overall character of the guitar sound.
The Eclipse and Robin sound best in my opinion. The Eclipse has that trademark "wall of sound" character that mahogany brings to the table. The Robin sounds similar, yet clearer in the mids IMO, and not quite as huge...but close.
This is intriguing, because I've never really given Ash a chance before. Maybe it's time to reevaluate!
