Journey Guitarist Neal Schon -- Judge Tells Ex-Wife ... Get a Job

Neal Schon just scored a big victory over his ex-wife -- a judge not only shut down her attempt to milk an extra $2,758/month out of the Journey guitarist, but also suggested she get a degree and support herself ... TMZ has learned.

According to court documents, Amber Schon wanted Neal to up his $3,000/month in child support to $5,758.90/month. Amber and Neal have 2 minor children ... Aja and Sophia.

But a family court judge in Minnesota -- where they were divorced in 2007 -- recently ruled against Amber, saying the requested increase was "intended primarily to upgrade her own standard of living."

And what a standard ... according to the documents, Amber's annual expenses include $7,200 for clothing, $5,760 for a storage locker, and $9,600 for birthday parties.

But the most shocking expense -- $2,400 on postage! Apparently, someone hasn't heard of email.

In the docs, the judge says Amber could be earning up to $36,000/year on her own ... if she'd just complete her teaching degree -- and added it's not Neal's fault she failed to "obtain any kind of employment."

Neal tells TMZ, "My concern is with my children and I'm infuriated they are being exploited and used to extort money from me."
