So, I'm having an issue with my flanger. When I run it off of battery power (2 x 9volts), it works fine. If I try to run it off of my BBE Supa Charger at any voltage: 9, 12, 16, or with a voodoo power adapter cable 18volts, it is varying levels of messed up. At 9 or 12 volts it basically does nothing sound-wise. At 16 or the recommended 18 volts, the pedal will oscillate audibly even if it's turned off. If you switch it on, you get an extremely loud burst of oscillating white noise (waaaaaay above unity volume) going through the amp. What are my options here? Anyone else running one of these pedals off of a pedal power supply.. especially a BBE Supa Charger?
