So, I'm at the point where I should be considering replacements for the tiny 387 bulb in my Morley PWB. At the very least, I could plunk down $5 for four of them through Morley themselves. But, as this is a pedal I intend to keep for a long time, I would rather get a bulb that I don't have to replace every two years (of consistent use, and constant forgetfulness). Naturally, this leads to LEDs. Why shouldn't I use an LED 387 bulb in my Morley? If the answer is "You should," then which one would be best?
