Re: Looperlative LP2



I am not sure if it's good or not that I am not the only one who had that "cutting out and resetting" issue. I am not 100% sure and I haven't done this very scientifically, but in my case everything suggests that it was the power supply that solved it. I tried it twice with the following signal chains:

1. Stock Fender strat into the LP2 powered by a standard Vooodo Labe PP2+ into a Fender Champ 600
2. Stock Fender strat into the LP2 powered by a generic 9v 200ma power supply into a Behringer headphone amp.

In each case I tried multiple mix and input gain settings. In the first case I had the cutoff problem occur every time I hit the strings hard, especially higher up the neck (that's single oil pickups, so nothing too hot) and the only solution was to turn the guitar volume down. In the second case I was unable to reproduce the problem at all.

Maybe LP2 does not like the PP2?

 I too encountered  this popping and reseting phenomena if I really slammed the strings hard, when demoing Rick's and I was using the high current ports on my voodoo lab PP-2 so I'm not sure the power supply is the issue. I also had to select the lowest gain setting because I'm running a pretty hot signal in to it with a wah, a couple of drive pedal and an ep-1 clean boost that I leave on and it converts the signal to low impedance. At the highest gain setting it was really pushing the front in of my princeton reverb and likely overdriving the chorus pedal and M-9 downstream. I was  was able to tame the issue by leaving the mix pot at about half way which gave good blend, but that ceiling and cutoff issue was troubling to me.  Regarding the feedback port. I believe its continuously variable so if you just back the _expression_ pedal off a bit you will get a more gradual fade slope. Also the length of the loop will determine how fast it fades, so shorter loops fade faster.
