The Tube Game

Welcome to the tube game, the sonic equivalent of Clairol. Want more bass, more warmth, more openness, greater depth, increased color, truer timbre, a warmer midrange, less brightness, more focus, and/or a tighter bottom end (don't we all)? Change your tubes. Often this will involve hunting down Old Stock (OS) tubes, which become more costly and rare with each passing month. But when your amp or preamp can take on different sonic characteristics simply by changing a few tubes, who with the time and money to experiment can resist the temptation?
