I have a Euro 5 that I would play lots more if she didn't weigh so much. I know I can shave about half a pound by going to Ultralight tuners. Is there a bridge that will "work" without a serious mod to the bass? The curved body has a little "shelf" the the bridge sits on. Ideally, a MUCH lighter bridge would dump a pound or more.
I feel the same way about my MusicMan Sterling.
It's my favorite bass, but I play it the least amount because it's so heavy.
I have seriously considered having someone router out the back, but I'm afraid I'll regret it and cry myself to sleep.
In addition to tuners, you could try getting one of the Spector rebop bridges. they are made out of aluminum and should be lighter weight.
Also, you could get Lace Alumitone pickups. There's not much too them as far as materials. They are super lightweight pickups. Not light on tone, though! I rather like the Lace Helix bass I have.
