I am having some issues with the reverb on my Allen 41S.
Problem 1. When the organ powers up, my organ is normally completely quiet and you wouldn't know it was on except for the power light. However, when you flip the reverb toggle switch, there is a light static noise which grows fainter after several seconds. Adjustment of any of the reverb voicing controls (treble, bass, input, output) have very little effect. Turning the input control does make minor improvement, but of course, I loose the reverb effect at some point as I retard it. Turning the reverb off again makes the problem go away. With the reverb on and listening very carefully, imbedded with the static is a very faint beat or pulse of about one beat per second.
Problem 2. The reverb works ok, as far as Allen reverb systems go. But there is a staticy noise after notes are played that sound similar to the noise the snare attachment makes on the bottom of a snare drum, except much quieter. Another analogy might be a very light drizzle on a tin roof. Indeed, when playing, I am not actually aware of the noise, but have the impression it might be raining. If I quit playing and just play a note or chord on any manual, I become aware of this noise which seems to dwindle slower than the notes as the reverb effect fades out. Again, adjusting the reverb voicing controls have little effect on the situation.
Thoughts: I know there are reverb dip switches, but I do not know the proper setting. I have not changed them, but someone in the past may have.
Is it possible that the problem is upstream of the reverb, a failed filter or something?
There are two different set of reverb voicing controls. Are there actually two different reverbs and can they be switched to see if the problem moves. Currently, it would appear that
the static plays on two channels as I hear it on both sides of the organ.
The problem is not that annoying. The reverb works as advertised. I just worry that it may be a messenger of an impending bigger problem.
Anyone care to share their thoughts?
