i have a very old technics amplifier and it has a button on it marked loudness.

the effect makes the bottom end sound a lot fuller and it pretty much makes anything sound a bit better.

is there a vst or technique you can use to do the same sort of thing, like a universal tweek u can apply to tracks to make them sound fuller? more as when trying to recreate the effect i have not yet been able to give that added beef quite like this old vintage bit of kit does.

have actually considered resampling productions after running them through the amp before.
