TUBE ROLLING — it works!
It's not enough to roll them around on your kitchen table, living room coffee table or even ping-pong or pool tables... you gotta roll them a lot more than that!
For a smooth glassy high-end, it's best to roll the tubes on a gymnasium floor or other similar hardwood surface, make sure it's clean though!
For a touch of grit, rolling your tubes on freshly paved asphalt works wonders.
For full on raunchy rock n roll distortion, only a rural gravel back-road will do.
However you like to roll, avoid backwoods wagon trails or anything like that, especially after rainfall: rolling in mud makes your tone muddy — duh!
