Strymon Ojai R30 Expansion Kit - Add Five High-Current Outputs

In this review the Strymon Ojai R30 Expansion Kit is evaluated as a practical way to grow an existing Strymon power system. The kit is aimed at guitarists and pedalboard builders who already own a Strymon Ojai or Zuma supply and need more isolated, high-current outputs without replacing their main unit. The single biggest reason to buy is simple: it adds five isolated outputs including two variable-voltage jacks so players can power more demanding pedals while keeping noise low and wiring tidy.

Key Features

• Five isolated outputs: The expansion provides five additional pedal outputs so users can power multiple effects without sharing rails or introducing ground loops.
• High-current capability: Each output supplies up to 500mA, which covers many modern high-draw pedals and digital stompboxes without overloading a single outlet.
• Variable voltage options: Two outputs are selectable for 9V, 12V or 18V, giving flexibility for pedals that require higher voltages.
• Easy integration: The kit connects to an available 24V Thru jack on a Strymon power system, making expansion straightforward and avoiding complex wiring changes.
• All cables included: The package ships with the isolated power distributor and the connection cables needed to attach it to an existing system, so setup is quick out of the box.
• Universal compatibility: Automatic international power compatibility ensures dependable operation on stages and in studios worldwide.

Who It's For

The Ojai R30 Expansion Kit is best for guitarists and pedalboard technicians who already own a Strymon Ojai or Zuma unit and need more isolated outputs to add medium- to high-current pedals. It suits players building larger pedalboards who value quiet, isolated power and want a tidy, modular expansion method.

It is less suitable for someone starting from scratch who does not already have a Strymon power supply, since the kit requires an existing Strymon 24V Thru source to function. Players with very small rigs or who prefer a single, all-in-one supply might look at full main units instead of an expansion module.

Pros & Cons

Pros

• Five isolated outputs expand a Strymon system without introducing noise or ground issues.
• High 500mA per output handles many modern digital pedals and buffers reliably.
• Two variable outputs that support 9V, 12V or 18V increase compatibility with specialized pedals.
• Includes the required cables and distributor for immediate integration with a Strymon setup.

Cons

• Requires an existing Strymon power supply with an available 24V Thru jack, so it is not a standalone solution.
• Powering very large numbers of high-draw pedals still depends on the total current capacity of the connected main supply.

Specifications

Our Verdict

The Ojai R30 Expansion Kit is a focused, well-built way to add isolated, high-current outputs to an existing Strymon system. For players expanding a medium to large pedalboard who already own a compatible Strymon supply, it delivers clean power, voltage flexibility and tidy integration at sensible value. Musicians starting without a Strymon base should consider a main power unit first, but for expansions this kit is a practical choice.

Frequently Asked Questions

Can I use the kit without an Ojai or Zuma main supply?
No. The expansion must be connected to an existing Strymon power unit using an available 24V Thru jack to function.

How many expansion kits can I add?
You can add up to six Expansion Kits in total, increasing the number of outputs depending on the main supply and total current limits.

Are the cables included for integration?
Yes. The kit includes the isolated power distributor and the necessary connection cables for immediate setup.
