The Godlyke Iso-Pump Voltage Regulator powers 12V, 18V, or 24V guitar pedals from your 9V Power-All Guitar Effects Power Supply - easily power a higher volt rated guitar pedal in your Power-All effects chain. Not all effect pedals run off 9 volts, and for these oddball units there’s the Godlyke Iso-Pump Voltage Converter (formerly called the Godlyke Power Pump Voltage Converter). Designed to work specifically with the PA-9 Power-All, the Iso-Pump takes 9V DC and converts it to 12V, 18V, or 24V DC, selectable via an external switch. With the Godlyke Iso-Pump, pedals requiring 2 batteries, pedals with internal vacuum tubes, and many digital units can be powered directly off the PA-9 without the need for a separate power supply. The IP-1 can also be used to get more headroom out of certain overdrives. Best of all, the IP-1 features our proprietary "Ground Hound" ground isolation technology which allows use of pedals with opposing ground configurations to be powered off the same series power supply! Tech TipYou can daisy chain pedals off of the Iso-Pump, provided that you do not exceed the maximum current capability of the IP-1 at the given voltage. Current capacity: 12 volts - 480 mA / 18 volts - 320 mA / 24 volts - 240 mASo for example - if you had two 18-VDC pedals each pedal had a current draw of 150 mA, you could connect these two pedals to the output of the Iso-Pump (set at 18 VDC) using our Cable-Y splitter and you would be able to power both pedals off the single IP-1.
