I purchased a T-Rex Sweeper Bass Chorus effect for my board, and play an MXR bass envelope filter as well. When I first tested the T-Rex pedal, there was a noticeable difference in tone and the chorus effect was heavy. Now, the rate and depth dont seem to make much of a difference and it's not a super noticeable effect. When I listen to this, I notice the effect much more than on my board... http://www.youtube.com/watch?v=abQE19k8LI0 My question is - has anyone else used this pedal and noticed the same thing? Could the way I have it set up reduce the effect? What is a better chorus pedal to try? Thank you!
