I've got a Zoom MS-70CDR [multi-effects] pedal, and a few people are saying not to use it via an aux send and return, owing to a comb-filtering issue. Have you noticed this issue with digital pedals on aux returns?
I've always advised my students to set their high-pass filter slope at a steep setting of 48dB per octave to reduce boominess. Is this the best advice to give my students, who are very much at the beginner stage?
I've recently bought a Klark Teknik KT-2A compressor to use with my Warm Audio TB12 preamp and noticed the TB12 has insert input and output sockets. What is the best practice when using outboard compressors with preamps when tracking?
