This is Module 6 of 9 of Friedemann Tischmeyer's Internal Mixing program.
This module deals with reverbs, depth and delays. Here are few topics discussed in this video: layering with reverb and delay, using external reverb modules, pre-delay as a design component, eqing reverb return as a design component, pre-fader or post-fader?, how many reverb units make sense?, delay in reverb or reverb in delay, design with the help of mute and special FX.
