I've been happily thumping away on bolt-on's for about a decade, and tend to keep my EQ flat. I just bought a neck-thru and discovered that the sound I was getting from my amp is actually pretty boomy and that my bass actually needs a bass-cut to keep the low bass under control. I'm assuming that I have been missing lots of fundamental all along and that the neck-thru actually has a flat response. I've always favored 1x15 boxes, but I'm wondering if that's because they had the screwy EQ a bolt-on needed to sound good? Has anyone else encountered this?
