Hi, I am very new to gear so I hope you can help me. I would like to reference the intro to Metallica's Fade to Black for this question. I need an intro (clean channel) to be played through my amp and then for me to play a lead over it through distortion channel using the same amp. I bought the Ditto looper pedal and I played the clean intro, then switched my amp over to distortion to play the lead and it also distorted the clean looped track, which is not what I need. I was wondering if there was a pedal that just plays the looped track, or a sample AS IS even if you switch to a different channel. or another easy way I thought of is to just hook up my ipod, hit play, and then do the harmony over it but I dont know the correct pedal or gear to make this happen. would the ipod track also be distorted if I played the song through my ipod on the distorted channel? Thanks for the help! PS please keep this as affordable as possible thanks!
