Thanks. Do all of them have active electronics?

There is an error on the Auction as it reads that this is the first Spector ever made. That is a false statement.

That "error" is probably driving up the price of that bass BIGTIME.

I'm pretty sure all Spectors are active electronics. There may be some from when Kramer owned Spector back in the 80's that are passive, but I'm not 100% sure about that.
