Digital gear, sample rates and killer hurts?

[operative451]

Hello! Ok, possible silly question time again, but....

My elderly zoom 505 has a 32khz sample rate and 18 bit input, 16 bit output, and 128 oversampling.

What?! So i know that for instance, the sample rate affects the frequency that can be sampled, and its about half, sort of? So the highest frequency the 32khz processor can hear is around 16khz - does a bass produce anything much higher than that (certainly that you'd want to hear anyway, i can happily deal with losing high frequency hiss and crackle).

And then there's this which throws the spanner right among the pigeons: http://productionadvice.co.uk/high-sample-rates-make-your-music-sound-worse/

In the case of my ancient zoom i'm using it at the end of the effects chain for limiting and a splash of EQ plus reverbs and delays if i fancy them.

So is it worth getting rid of the digital kit completely or is it actually not going to make much of, or any difference? There's any amount of stuff talked about digital vs analogue vs valves etc, and most of it bamboozles me a bit. My analogue fuzz and distortions do sound more pleasing to me than the digital ones, but that might just be my zoom being a bit rubbish at distortion!
