Started to dig a little deeper into how to best use the Tube Compressor.
Found that conservative settings produce rather subtle and a bit surprising results in level changes.
Have no idea how the real thing is used and how the controls translate.
It seems the Level parameter is just an output gain makeup adjustment whereas the Threshold parameter is either the same or similar to the 'Gain Reduction' on the LA-2A.
I noticed that I have to set Level at 4% for thresholds 100-70% to maintain my output level, which is surprising because I would have thought that the more i compress the more I need to raise the makeup gain level.
Starting at 65% threshold and down at 0% Level the compressor output actually went up starting with about 1.3dB for every 5% Threshold change and ending with and increase of 0.5dB when Threshold is changed from 10% to 0%. I would have expected that I'd have to increase the Level to make up for Gain Reduction. I ended up being able to only compensate for output level increase till about 60% threshold. From 55%-0% my level went up by 13dB on extreme 0%Threshold setting.
How are you using this effect, what settings work for you, any other interesting things you can share?
