Does anyone have an instruction sheet for an Aphex Punch Factory or can suggest some settings? I received a used one yesterday and I'm still trying to determine if it's even working properly. Either this thing is *way* more subtle than any other compressor I've used, and if so, is not what I'm looking for, or it's not working properly and needs to go back. I get activity in the LED compression display (even when bypassed) but it has virtually no effect on the audio. At most, a barely perceptible sustain enhancememnt. I've tried setting it any number of ways, tried the active and passive input setting, and tried 3 different basses, but nothing has made any difference. Is this thing even supposed to be able to squash the signal a little bit? My main concern is verifying that this thing is working properly soon, so I know whether to arrange a return or not. If it's working as intended, but just not doing what I expected, I'll see if I can resell it and consider it a lesson learned.
