RIP the buddha box....
Well, it had to happen. After travelling to various locations in Europe and being used many times on stage and in the studio it's now deceased...
I've just spent all of yesterday and most of the morning today trying to get it working again,. It's still 'working' as far as the echo goes but the input level has reduced to virtually nothing, just a crackly, incredibly faint sound. I'm guessing it's using a diode on the input as a form of cheap amplifier but my knowledge doesn't extend to the go beyond that as anything but theory (and the fact there is a small diode on input).
Can anyone suggest any other tips on troubleshooting or should it just go six feet under?
