Which would be closer to putting an eq into the fx loop of an amp?
Is the eq on front pannel (bass,mid,treb) when set in post eq after the amp before the cab and the effects block is after the cab block?
no. EQ Pre is before the preamp gain and post is after the preamp. Post would be closer to in a loop. Pre is really useful for tailoring the distortion characteristics as it works similarly to a Mesa Mark Series.
