Zero-noise, Worldwide Pedal Power

The all-analog Strymon Zuma R300 packs five pedals' worth of clean-burning FX fuel into its compact aluminum chassis. Like the elder Zuma, the R300's 500mA outlets are more than capable of powering your high-draw digital reverbs, delays, and loopers. The R300's 2-stage isolation completely eliminates ground loops and AC line issues for noise-free performance. It even has a switchable 12-volt/18-volt outlet to keep you from having to run separate power supplies. Worldwide power and expandability down the road make the Strymon Zuma R300 a power supply you can keep on your board forever. A detachable IEC power cable facilitates tidier travel.


Conveniently expandable

The Zuma R300 pedalboard power supply has enough juice to power five high-draw pedals. But not to worry — the R300 expands as your needs do. It features a 24-volt thru jack for adding additional Strymon Ojai 5-output power supplies to your board. And since the Ojai series boasts the Zuma's same clean-signal technology and flawless performance, it's the perfect way to expand your R300.


Built for the traveling guitarist

The Strymon Zuma R300 is engineered to handle the demands of today's gigging guitar and bass players. Besides its impressive powering capabilities, the R300 is built extremely rugged. Its anodized aluminum chassis will protect its circuitry for years to come, whether mounted on top of or underneath your board. The R300 even boasts the ability to work with various voltages (120-volt, 240-volt, and 100-volt) around the world, making it irreplaceable on many pedalboards.

CITES regulations concerning the export of items containing certain woods affect any guitar sold ouside of the European Union and which contains any quantity of either Rosewood or Bubinga.  In these cases, an additional charge of £80.00 will be levied per species after the sale to pay for the required re-export certificate.  There will be a delay in dispatching any guitar containing either Bubinga or Rosewood of up to 4 weeks while we obtain the necessary certification for export. As the charge is per species, where a guitar contains both Bubinga AND Rosewood, the charge is doubled to £160.00.  We will contact you following your purchase of any guitar containing a controlled wood and advise of the charge once you have placed the order.  You can make payment for the charge by sending a Paypal payment to us at: sales@fxpedal.co.uk. 

Note that CITES only applies to guitars containing Rosewood or Bubinga that are being exported outside the European Union.  Guitars being delivered with the United Kingdom or in the European Union will be dispatched as normal.
