Hi there. I have a 1982 fender Concert and a few stomps (OD3, Power Screamer and DD20). Recently i joined a cover band and i had to purchase a MFX: i got a used Boss GT8 and i'm quite happy with effects quality but it really sucks tone. Well, not exactly: it cuts dynamics! I need a floor mfx in this range price that allows me to have good effects but most important keeps at least a very good dynamic. What about the other mfx: Pod XT live, Tonelab, Gnx 3000, Zoom g92tt??
