So I was recording a fender hotrod deluxe with the spring reverb cranked going into a a sm57, and when I hear the recording back through headphones you can’t really hear the reverb and delay on it as much as in person, however when I add another Marshall amp and record it with a rode NT1 I can hear the effects much more clearer. Is this normal? Should I just record reverb and delay heavy guitars in stereo rather than mono, or is there some work around this.
