This can only be done if u are using a Multi effect that has a Line-out Jack.
Always turn on yr Cab-Stimulator so that it sounds more natural
Line-out signals are suitable for direct input into computer /laptops line-in function. This will ensure good and clean recording.
Also, make sure that your recording does not peak. Peaking results in distortion. And believe me, it's not the distortion we want.
For recording thru the effects pedal (analoge ones), it's super tricky. If u line in directly, it will sound harsh as the signal is not converted. Using a D.I doesn't work.
Best if u can do this
Guitar -> Effects -> D.I -> Mixer -> Recording out -> Computer
Best if the D.I is like Sansamp etc. so that u can the tone of a real amp, esle it will sound too sterile.
Or
Guitar -> Effects -> Mike -> Mixer -> Recording out -> Computer
And also, if i am not wrong, most 1/4 to 1/8 convertors are stereo haha
You can get it at any havey normans, and of coz Sim Lim. Y pay for Proel when u can get the things most sound guys use over at Sim Lim and it's gold plated some more hahaha
