You would think the solid colored Forums would be the typical Peavey poplar just for cost savings.I had a 5 string and the body was ash. It was a great bass but it weighed too much for me.
I think 12 pounds or more is what it weighed. Mine was sunburst and was easily identified as ash.
My ash Gen 1 Fury weighs 9.1 lbs, significantly more than my poplar Gen 2 Furys at 8.25 lbs but not waaaay more.
Still don't know why a four string Forum with one pickup and a pre should be crazy heavy.
