I've had my MicroPog for a few years, and had it mounted on a really ghetto-looking DIY pedalboard. So I scored a really nice Furman SPB-8, with 8-9VDC outlets. A plugged it in with my pedals (Korg tuner, X2 wireless, BBE Sonic Maximizer) into the Furman, using the patch cords, and it all seemed fine. After a few minutes of use, I got some really strange feedback-type sounds and I shut it all down to avoid any damage.
After a bit of isolation troubleshooting, I narrowed it down to the MicroPog. I tried using a wall wart, instead of going into the Furman, and it all worked fine, so I swapped out the patch cord, then tried using a different power outlets on the Furman. I got the harsh, squealy, echoey sound again. The only way it works properly is with the wart.
Now, I know I can simply use the wart and call it good, but I want this thing to work the way I intended it - with four small patch cords going to the four 9VDC power outlets, neatly coiled and velcroed down. I'm seriously OCD, and I need complete order and tidyness in my pedal world.
Besides, I need the 3-120VAC, 15A outlets for my Roland PK-5A, my E-MU synth module, and it's amp.
Any ideas about what may be going on? I tried using a polarity reverser, and it wouldn't even power the MicroPog up, so I assume the polarity is fine. I can probably make an audio recording of the harshness and SoundCloud it, if anybody needs to assault their ears to help diagnose it. Thanks, in advance!
