I need suggestions on how to practice under headphones. I want to take a line out from my cd/radio player and mix it with my bass signal so I can practice under headphones. My amp does NOT have a headphone out and does NOT have a cd/aux input. It DOES have a balanced DI out. Any suggestions on how to mix my bass signal and a cd player signal together so I can hear them under headphones? With or without using my amp. Can I get a cheap "mini mixer" and accomplish this? Will the mixer "amplify" the bass sound if I go directly into it? Or do I need to send the mixer an "amplified" signal? I tried the Ctech Pocket Rockit mini headphone amp, but I thought it was kind of cheap and cheesy. I'd rather have alittle more control over the sound I get. Any other suggs without breaking the bank? thanks, and sorry if the ? is kind of stupid.
