Chase'les' & Freeze (Agf Guitar Sample)

Darlings.gx.Last update July 2016. Enhanced and improved.Clean (cl), crunchy (cr) and overdriven (od) guitarix sets of Roland JC-120, Voxes, Fenders, Marshall JCM-800, Mesa Boogie.The clean sounds with reverb (rv) and a bit chorus (ch). The overdriven sounds sometimes with compression (co).Normally I prefer the tonestack, but sometimes the amp impulse seems to do a better job. Try it yourself. And try putting it in front of or behind the valve section. It sounds different!...
