Enclosure not stated
From the vendor
Need 18V to give your overdrive some headroom? POW!
Need -9V for your posi-ground fuzz? POW!
Sweet little board that will give you:
• An 18V supply of around 20mA (depending on the IC used) from a standard 9V supply.
• A -9V supply from a standard 9V supply, so you can power your posi-ground pedal on the same power daisy chain as your standard polarity effects.
• Optional Starve control on the -9V supply to simulate a dying battery.
Please note: due to the relatively low power output it is recommended that you use one of these for each circuit requiring the power. 20mA isn't a great deal. Check your pedal power consumption if in doubt. Not recommended for battery use.
The starve pot (if used) is board-mounted for minimal wiring and easy enclosure mounting.
Kit includes: PCB, all components, hook-up wire.
Difficulty: Easy
PCB size: 25 x 22mm
