I know this may be a beginners question but I am fairly new to recording so I bare no shame lol. I was talkin to the support people for my interface (Focusrite scarlett solo) and the guy told me in order to plug my amp into my interface I needed to use either line out left or line out right. I had to make sure my interface was on line instead of instrument, plug the guitar amp into my interface and then my guitar into the amp. I did this and it wouldnt record and I could hear myself outta the amp instead of thru the headphones plugged into my interface. I have a Fender G-DEC 30 guitar digital entertainment center amp if that matters.

The way you have it set up is you are not actually going into your interface, rather going out from the line out (either L or R) to the amp.

Are you trying to record the guitar amp itself?...if thats the case then there are two ways...probably the easiest way would be to plug your guitar into your amp, then mic the amp at the front of the cabinet around 2 to 4 inches an front of the speaker with say something like a Shure SM57 or SM 58 or similar then run the mic into your interface.

If the amp has a dedicated Line Out that is clearly marked as such, Which your fender G-DEC 30 does, you could plug this into your interface as this would be a line level output that can be plugged into any line level input such as those found on audio devices. But if the amp does not have a dedicated Line Out that is marked as such, don't use this method, it can damage the interface.

Make sure the interface is set to Line In then plug a TRS cable from the Line Out from the amp to the Line In on your interface, zero all your volume pots, plug your guitar into your amp and set your gain levels to suit.

I was meaning that I ran a cable from the line out right or line out left on the back of my amp to my interface. My interface was set to line. My guitar was then plugged into my amp. I had headphones plugged into my interface but I could only hear it comin outta my amp and not thru the headphones. Everything else I could. My interface was all selected correct and all.

When I asked the support guy on the interface website he said the same thing as you, to plug the amps "line out right" or "line out left" to the interface then plug my guitar into the amp. Also to make sure it was on line instead of instrument. The headphone way got the sound into my computer when I tried it one time but with the "line outs" way the sound came through the amp instead of my headphones. I'm not sure why.

Thats because when you plug a cable into your headphone jack, it switches the signal going to the speaker to the headphone circuit, eliminating sound coming from the speaker.
Do you want to hear the guitar coming through the amp or just the sound of the amp into the interface?

You should be able to hear it when you plug directly into the interface..yes.

Ok, now we are on the same page...try plugging another set of phones if you have them or another cable into the headphone jack of the amp, this will switch it from the speaker, effectively silencing the speaker. I'm not familiar with the amp in question, but if the line out circiut is on a seperate circuit it should still send a signal from the line out to the interface.

Then try to monitor only via the interface.

Another option would be an amp simulation plug-in...there are many free amp sim plug-ins available, and you then have options of changing settings to suit the sound you like, and can monitor in real time your track with the plug-in on the track via the interface without having to use your amp.

I have attemped them a couple times. They are definitely pretty cool, the plugins are. I am jus filled with curiousity because its all so new and fresh I like to try everything lol. The plugins amps on ableton are mainly distortion stuff. Can't find a nice clean sounding one for my softer music moods.

Iv'e never tried it...not knowing the output impedence of the headphone socket I wouldn't recommend trying it without knowing if it would damage your interface or not.
