On the left: Electro Harmonix' new Holiest Grail reverb pedal. I can't work out if it's all analog or partly digital, but it looks utterly analog and rock'n'roll, and it might even have a real spring reverb in it, so you can kick it for that cool boingy noise. On the right, Waves' new IR-L cut-down convolution reverb plug-in. It's pure geek power, the opposite of rock'n'roll, but convolution is black magic. The hardware: $225, the sofware is $400.
