Default looking for a new spin on guitar fx pedal psu

Hi! I have recently had the urge to build an effects pedal psu that acts like a low or dead battery. This psu would have a huge amount of sag and maybe an adjustable rate of "recharge" or refresh.
Does anyone have any idea how to do this? Maybe a big cap after an under-rated regulator? I love the compressed and distorted sound when you have a dying battery in your overdrive or chorus pedal. It would make for a neat effect. cheers!

To be honest it sounds a pretty silly idea?, but to do it simply add a series resistor in the lead from the PSU - as a battery goes flat it's internal resistance increases.
