As anyone who owns a spring reverb module knows, the A-100's 
transformer generates a lot of hum. In addition to the spring 
reverb, I use a lot of electromagnetic pick-ups (like on a guitar) 
as external signal inputs  and find the hum almost unacceptable 
with this set-up. I hope someone might have suggestions for 
shielding the transformer, or knows of other ways to decrease 
the hum generated by the A-100.

My A-126 Frequency Shifter seems to add a sine wave of almost 
equal strength to any signal I plug into the module, has anyone 
else had this problem? I don't seem to be able to frequency shift 
anything without adding a loud sine tone to it, even when using 
high input signal coming from an A-110, for example.

I'd also like to know about ways to create a manual gate, without 
a keyboard. A simple way to open/close a signal path...

To the person who asked about the spring reverb, I like it a lot. It 
adds a very characteristic sound of its own, because of the 
resonance of the springs, so it's in no way a "neutral" sounding 
reverb. The springs offer very tactile ways for changing sounds 
though, because they're very sensitive to vibration.
