So I have a Digitech RP155 and a Line 6 Spider IV 15 amp. I want to record using the tones on the amp, not the interface, but I don't know what I'm supposed to do. I know it's possible, but I'm lost with what to do. I bought a Y-adapter, plugged both ends into the outputs on the RP155 and connected my amp's output to that, then plugged my guitar into the amp. I get the sounds, but it won't record. What should I do?
If you want the sound to go INto your interface, you might wanna use the INput, not the output.
The way you use the tone on the amp is to use a mic to record the amp. Do not input it directly. Mic quality will affect the sound.
