I currently own a line 6 spider 2 150 watt head with a line 6 4x12 cab. After playing on someone else's peavey 5150 I wanted to immediately sell my line 6 and get the 6505 (since the 5150 is now the 6505). I was wondering has anyone out there has ever used a 6505 or 5150 with a line 6 cab? I'd rather not have to get a new cab, but I would like to know if anyone else has experienced issues or disappointments using a 6505 with a line 6 cab.
