So this past Saturday I bought a MXR M87 Bass Compression pedal. I was very pumped. However, when I hooked everything up I couldn't get the gain reduction LED's to appear. The blue light came on (on the pedal) and there was a significant boost in volume, but no matter how I tweaked the pedal (attack, release, input, output) I could not get the LED's to register.
I have a Fender Select P running into a Fender TV 15.
The TV 15 is 350 watts, Tube preamp, solid state power amp and has both gain and volume controls.
I brought the pedal back had them try it.
They plugged it into a Mexican P and an Acoustic B10.
The pedal worked perfectly.
I bought the same power adapted used at the store and went home to try it again.
Absolutely, no change. I had the exact same thing happen.
I tested both of my chords and both work.
Does anyone have any ideas as to why I cant get this to work?
