I have to ask....it sounds like you are talking about a singular monitor. Are you mixing in mono?
Had 2 monitors, only 1 now.
My Recording Equipment:
RP355 guitar multi-effect processor
Focusrite Scarlett 2i2 is a 2 in / 2 out USB recording interface
Sennheiser e 609 Super-cardioid mic.
Blackstar HT-1R Studio/Practice Tube Amp
Speaker cab with Celestion G12M Greenback speaker
1 JBL LSR2328P 2 way Powered Studio Monitor
Audacity DAW software
Cubase LE 5 DAW software
Fender
Strat electric guitar
Backing track download
I use stereo with my DAW software only when I have 2 sources of input to feed both inputs of my Focusrite 2i2 usb interface. Otherwise mono. When I say I use 2 inputs sometimes to the usb interface I still only am recording the one source my guitar but to both input channels for example 1 from the Miced cabinet along with a direct output from the RP355 for the other input. I test and set the input levels on the usb interface while watching the DAW softwares bargraphs first before recording.
All that being said (sorry) and knowing that I only playback thru the laptops internal spkrs. or headphones on the laptop (by the way the headphones always sound a ton better than the laptops speakers).
What sounds best is when I don't mic anything and don't use my guitar amp but feed both outputs from the Digitech
Effects/Amp simulator direct into both inputs of the usb recorder interface.
2nd best would be micing the guitar amps cabinet along with 1 output from the Digitech.
3rd best would be recording mono just the miced cab.
4th best would be the emulated output from the amp which sound horrible.
