Tightens up the Chorus just a bit.
Apparently 5.7v reduces the delay down from 24ms closer to 18ms.
I also tried 6v and 6.7v but they seemed to darken the pedal somewhat.
5.7v seemed to be the sweet spot.
I'm building another Glam at the moment, so I'll be able to compare side by side to see if it's really that noticeable. But it only requires 3 additional parts, 1k resistor, 1n4001 and a LED.

6V = 18ms
6.5V = 16.5ms
7V = 15ms
7.5V = 14ms
