Sir Elliot has introduced Loud & Clear, a free preamplifier effect for Windows.
Here's what Sir Elliot has to say about Loud & Clear:
This is a very basic preamplifier designed to bring forth the upper midrange frequencies. It works well on Rock hence the reason of the PA head look. Volume will be the least of your worries using this preamplifier.
