Studio One users, your free Friday plug-in is the GK Amp 2 LE from Audified.
A scaled down but no less impressive version of the GK Amplification 2 Pro Bass Modelling plug in.
This is an emulation of a bass amp from Gallien Krueger and is part of the free Live Guitar and Bass Bundle LE, which features free versions of guitar amps and pedals as well as the GK bass amp.
You get a single amp model with a single speaker and mic option compared to the full version but the sound with those options selected is the same.
