No... Preamps are built with op-amps (analog) or transistors, FETs, or vacuum tubes. You don't use a (digital) programmable microcontroller.
A regular-old bass amp has a preamp section and a power amp section. There is no digital and no software.
...You can do DSP (digital signal processing) but you generally need a preamp in front of the microcontroller.
And if you wanted to do this, the Arduino isn't the best choice. The ADC (analog-to-digital converter) is only 10-bits and it's a little slow (but it might be OK for bass), it's not powerful enough to do much real-time audio processing, and there is no DAC built-in (digital-to-analog converter) so there is no (built-in) analog output.

I doubt it, rail-to-rail audio-class opamp(s) would be appropriate.
If you want digital audio processing in realtime, the Arduino Mini doesn't have
the horsepower.
You could use a microcontroller to control a preamp circuit (switching analog switches,
driving a digitpot, acting as noise-gate), but the key signal path would be all analog.
Hi all,
Thank you for all the input. I will proceed with an analog solution.
