guitar identification - your help is needed

[nico spahni <nicosp@gmx.net>]

Can anyone help me identify this guitar (what make etc.)? I got it 
about 15 years ago for about $100 and never really bothered to find out 
what make it is because I didn't now how I possibly could with only a 
logo. There's no name, no serial number, nothing. The fact that it has 
DiMarzio pickups didn't help either. Only lately has it occured to me 
that some of you guys might recognize the logo. Have a look:
