Got my horrid Halloween sound effects (about a three hour MP3 disc I gleened from eight library sound effect discs) AND evil sound system going. I am using an ancient Pioneer hundred watt receiver and an old dual fifteen JBL bass cabinet. Sounds fucking awesome. Deep and scary!
A bit early, maybe.
... but last season it was raining constantly and near freezing. Kind of a struggle to set things up. Then, Not many brave souls came about. I was ready! This year I am ready early.
This year I plan to start making noise a few days early AND stockpile many buttfuls of candy.
