Hi guys i have a spider 4 15v. I bought a cable to use my phone as a playback device. It works but there is a problem. The playback sound is so low compared to guitar's sound. I have my phone's sound level max and its still low. I need to use my guitar at minimum sound possible(the knob on guitar) and when i do that guitars sound gets bad. And my second question is do i get background noise at high sounds levels of clean and crunch tones because my amp is only 15 watts?
