I mentioned that I believe amplifiers to be the most important element in the signal chain in regard to tone.

However, there are cases when I'd say that the amplifier isn't the most important element in the signal chain.

For instance, playability is also key. I know I can achieve better tone with a bad guitar and a great amp, but I'd usually choose a great guitar and a bad amplifier for playing live. Being able to play smoothly will increase the confidence more.

So it's down to which is more important at the task at hand; tone or playability?
