I've done it. There is almost no difference until the DRIVE knob is turned up about 2/3, but after that the difference is audible. It's not a huge difference, the background noise is still there, but IMHO it's definitely an improvement. Which is great for me, because I'm using only single-coil guitars (mostly a Telecaster) and I can use all the breaks I can get from the hum. I'll probably shield the pickup and controls cavities as well in the near future.Originally Posted by duhvoodooman
The change is probably not worth it at all for people using humbuckers or noiseless single coils, but it did make a difference, albeit small, for me. YMMV.
