Hi Geoff,
Was it an acoustic double bass or was it a new fangled solid body stand up bass?
I like to record bass with compression. I use a LA610 preamp with its built in LA2A style limiting amplifier. I like to use the limiting to get a specific sound. However, I don't see the merit of using a limiter to mask or hide a sound that I suspect is the result of a mechanical or electronic issue that can probably be eliminated in the future.
Your signal levels are no where near clipping... so using a limiter to prevent clipping doesn't seem like a priority.
Finding the source of those clicks seems like the way to go.
After all, if you limit those clicks on the way in it will just be harder to find them when you use the wave editor to edit them out by hand. :-)
I'm curious to learn more about the instrument.
If it's acoustic double bass I'd opine that loose clip on mics or loose after market electronics are common issues.
If it's a new style solid body... it still sounds like something is loose and clicking or knocking.
best regards,
mike
