the first Noise-Free "switching" power supply for pedals! You can toss your OneSpot, Godlyke, Trex, Joyo, etc. because they not only hum, they hiss, and they emit strange synth-like notes with certain pedals.

.

ALL other switching type adapters hum! Believe me, engineering one that doesn't was a huge undertaking and headache, but I did it.

plenty of available current; 800ma.

 IPS-9 is a MUST-HAVE for all owners of older 9 volt powered MDV-1, MDV-2, and MDV-3 because of the massive amounts of current it offers. (800ma) The older Deja'Vibe models mentioned have internal 18 volt conversion, and we've recently discovered that they need the extra current to sound their best because there is a large amount of sag at a certain part of the oscillation cycle.
