thank you, that’s a nice app. It works on all but Spotify, I can’t get reVamper installed on my phone because I’m not going to root my phone for that ;-)

Thank you, I’ll give it a try. I just didn’t see anything listed that I could add that effect.

Edit: been tinkering very lightly with this and I really like it and have decided to buy it even if it doesn’t do what I originally posted. It really brought the music “alive” in my truck with just one of the presets. Thank you again for the recommendation.
