It's very nice to see such a fine example of the Z1 posted here. I still have mine after all these years, but think mine is a little older than this one. There is no serial number on the back of my headstock, and mine has a Lasido decal instead of the Godin Z1 marks.
The color scheme is almost exactly the reverse, with black body (with tiny colored bits in the paint--you can just see them in the shot of the headstock on the bass pictured above), blonde neck and headstock, all black hardware. Same fingerboard.
I got mine new at the shop where I worked, so I got a good deal, but can't remember the exact year.
I really loved how the harmonics I played were captured so nicely by the pickup, but did not like the fret noise and finger slide noise with round wound strings. The balance I wanted was very tough to achieve. Often, the pickup would capture the tone of the part of the string between the finger and the nut too well. I solved many of those issues by tearing out the frets (Gasp!), and experimented with different sorts of strings. Recently installed a set of GHS flatwounds. They don't sound too frumpy--was happily surprised.
Often thought it would be fun to put that same pickup/bridge/electronics in a standard PJ style instrument and mix the outputs. Would never dream of installing ordinary pickups in this bass--the plain body is so unusual, and is sure to start nice conversations whenever I appear with it.
