A quick review of the Peavey Revalver 4.
This is my go-to software amp modeller. It comes with a big array of Peavey amps as well as amps from other brands such as Mesa Boogie, Orange, etc. The FX list is quite large. I use it a lot in studio recording situations. The fact you can change the impedance interaction and also mess around with the schematics of each component besides the basic options of changing the cabs, impulse responses, mic position and so on to achieve your desired tone makes this software extremely powerful. For all that you get in this software, it isn't that expensive. A winner for sure.
