I got a problem with my FBV longboard. The wha pedal seems to work for a while every time I switch on the amp (HD147) + the FBV, and after some time, the wha is not working anymore. I can switch it on/off, but it doesn't make any wha sound... except from a nasal sound once it's switched on, until I switch it off. The rest is working just fine. Also, I want to precise that the amp + FBV were purchased recently, and I've only played for three days with the gear.

Thank you!
