The Heavy 5150 is an amp simulation of the well known Peavey 5150.
You are looking for a heavy metal sound? Here you go! This is a classic disorted sound and it is really good. Downsides: Gain/Disortion level is not adjustable (just 0 and 100) and it uses quite some CPU power.
I’ve made a demo for you!
Looks like an amp.
Great sound but not versatile in disortion. The EQ works well.
~4,8% on my FX6300
Personal opinion: 7/10
It sounds good but is more or less an one-trick-pony. And you cannot run many instances due to the load.
