Strymon Ojai Expansion Kit 5-Output 9V Power Supply Expansion

In this review the Strymon Ojai Expansion Kit is assessed as a practical solution for players who already own a Strymon power supply and need more isolated outputs for a growing pedalboard. The kit's single biggest advantage is that it provides five additional high-current, fully isolated 9V outputs that integrate seamlessly by linking the 24V In to the 24V Thru on an existing Strymon unit, making it ideal for players who want clean, reliable power without reworking their whole rig.

Key Features

• Five isolated outputs: Adds five high-current 9V outputs to an existing Strymon power system so more pedals can be powered with isolation for low noise.
• High current capacity: Each output supplies ample current for modern effects pedals, helping avoid sag or underpower on high-draw devices.
• Expandable system: You can chain up to six Expansion Kits to service a large pedalboard, enabling up to 30 additional pedals depending on the host supply and current needs.
• Easy integration: Connect the kit by routing the 24V In to the 24V Thru of an existing Strymon supply, keeping setup simple and cable clutter minimal.
• Includes connection cables: Ships with an isolated power distributor and all required cables for integration so nothing extra is required to start expanding.
• International compatibility: Automatic international power compatibility ensures consistent performance on stages and in studios worldwide.

Who It's For

The Ojai Expansion Kit is best for guitarists and bassists who already own a Strymon Zuma or Ojai power supply and need more isolated 9V outputs without replacing their existing unit. It suits players building medium to large pedalboards who prioritize noise-free operation and reliable, high-current delivery for modern digital and analog pedals.

Players who do not already own a compatible Strymon supply, or who prefer a single, very large centralized supply with integrated sockets, should consider a complete power unit instead of an expansion module. This kit is designed specifically to extend a Strymon system rather than act as a standalone mains power supply.

Pros & Cons

Pros

• Clean, isolated outputs reduce ground-loop hum and interact well with noise-sensitive pedals.
• High-current outputs accommodate power-hungry pedals and help maintain headroom.
• Modular expansion lets users grow a Strymon-based power system incrementally without redoing cabling.
• Includes necessary distributor and cables for quick integration with existing gear.

Cons

• Requires an existing Strymon power supply with the 24V Thru jack, so it is not a standalone solution.
• Chaining many expansion units requires attention to the total current budget of the host supply.

Our Verdict

The Strymon Ojai Expansion Kit is a sensible, cost-effective way to add clean, isolated 9V outputs to an existing Strymon power system; it is especially good value for players who want modular growth and reliable high-current delivery without replacing their host supply. Buy it if you need more isolated outputs and already own a compatible Strymon unit.

Frequently Asked Questions

Do I need a Strymon power supply to use this kit?
Yes. The kit connects via the 24V In to the 24V Thru on an existing Strymon Zuma or Ojai supply and is not a standalone mains supply.

How many pedals can I power with multiple kits?
You can chain up to six Expansion Kits, which can provide up to 30 additional outputs, though total capacity depends on the host supply's current limits and the pedals' draw.

Are the outputs isolated to prevent noise?
Yes. The five outputs are fully isolated to minimize ground-loop hum and keep signal paths quiet.
