Yesterday Joran and I compared his Greco to my RI Rivoli.
We measured the scale lenghts. The Rivoli is 30,5" and the Greco 33,5, so the difference is only 3". The bridge seems to be around an inch more to the back, so the bass isn't that long.
The Greco has a three piece maple neck, while the Rivoli has a mahogany one.
Mark's Greco didn't have the two way switch and this one has. It's a mini toggle switch, which seems to be aftermarket and... ....it doesn't do a thing. Maybe a cosmetic mod to make it more like an EB2?
It's a gorgeous bass and because of the maple neck and scale length she sounds very tight and very usable in a rock band. We only tried her through a little Vox AC4, so it's difficult to say more about the sound.
