Realistic Amp Sim VST
LeCto is a free guitar amp simulator by LePou.
The VST is inspired by an American modern high gain head.
It can go from crunch to high gain.
The LeCto amp sim features:
oversampling, mono/stereo, drive, frequency controls, presence and resonance control.
LeCto is only an amp simulator, so you need to use a cabinet simulator as well.
Be sure to check out LePou's
LeCab2
as well.
It's a cabinet (guitar or bass) impulse loader that can hold up to 6 different IR files at the same time.
