LePou Plugins has released a Mac version of its Le456 preamp effect plugin.
It’s a preamp sim roughly based on a famous German gear. It has 2 channels and 2 modes per channel. Each channels/modes share the same features.
Apart from the usual tone controls (drive, low, mid, high and contour), each channels/modes offer two different tone stacks that can be accessed via the focus switches. Bottom and bright switches can be used to boost the low and the high frequencies respectively. On the low gain channel only (Clean/Crunch), the effectiveness of the bright switch decreases with the gain settings.
Le456 is now available for Windows and Mac (VST/AU) as freeware.
