This unit gives you 12 separate power rails, so you can run many effects without fighting for electricity. You can dial the voltage up to 18V on most channels, or push two channels together for 36V if you need more juice. It fits easily on a small pedalboard, but you must buy the Y-cable yourself to link outputs. Great for builders who want clean, adjustable power without buying multiple bricks.
Pros
- Delivers 12 separate power outputs for many pedals
- Voltage ranges from 9V up to 18V on specific channels
- Two outputs combine to reach 36V for high power needs
Cons
- Does not include the Y-cable needed to combine outputs
- Total current limit is 2000mA across all pedals combined

How to choose the best guitar effect power supplies
Build Quality
Palmer's German engineering shines. These units feel rock solid, with robust metal enclosures that can take a beating on the road. It's not just about aesthetics; a solid build means less noise and more reliability - crucial when you're trying to nail a dynamic performance.
Clean Power Delivery
Palmer's known for delivering exceptionally clean, stable power. This minimizes noise and hum, and, crucially, preserves your pedal's intended tone. You'll hear the difference - less muddiness, more articulation, especially with darker-voiced overdrives and fuzzes.
High Current Capacity
Many pedals draw more current than you think. Palmer power supplies consistently deliver the amperage needed to run multiple power-hungry pedals without voltage sag or erratic behavior. This is especially important for those with a full board loaded with boutique fuzzes and analog delays.
Isolation
Proper isolation between outputs is vital to prevent ground loops and noise. Palmer's designs emphasize this, which translates to a quieter signal chain - a huge benefit in shared rehearsal spaces or venues with questionable wiring.
Noise Reduction Technology
Palmer often incorporates features like PQSS (Power Quality Stabilization System) which actively regulates voltage and filters out noise. While subtle, this contributes to a cleaner, more defined sound, allowing your pickups' nuances to shine through without being masked.
Buying guide
Look, we've all been there: a pedalboard that sounds amazing in the bedroom suddenly craps out mid-set because of a dodgy power supply. Palmer's been making reliable, high-current power solutions for guitar effects for decades, and they're more than just a power brick - they're a safeguard for your tone and your sanity. If you're serious about your sound and need something you can trust night after night, let's dive into why Palmer's a name you should know.
Palmer power supplies aren't the cheapest option, but they're an investment in the longevity of your gear and your sanity. Don't skimp on power - it's the foundation of your tone. Watch out for generic 'clone' power supplies; they often cut corners on components, leading to noise and unreliable performance.
If you're running a full pedalboard with a lot of analog gear, the extra cost is easily justified.

Questions
Are Palmer power supplies truly silent?
'Silent' is a strong word, but they're remarkably quiet. You're unlikely to hear any significant hum or buzz, especially compared to cheaper alternatives. Any residual noise will be minimal and generally masked by your amp and guitar.
Do I need a regulated power supply?
Absolutely. Unregulated supplies can fluctuate in voltage, impacting your pedal's performance and potentially damaging them. Regulated power like Palmer's provides a consistent and safe voltage.
Can I use a Palmer power supply to power my amp?
No, Palmer units are designed solely for powering effects pedals. Attempting to power an amplifier with one could damage both the power supply and the amp. Stick to their intended purpose.
What's the difference between a DIN and a 9V DC jack?
DIN connectors are a standard size used by many pedal manufacturers, while a standard 9V DC jack is smaller. Palmer supplies often offer both, but check your pedals' requirements to ensure compatibility.
My pedals are drawing a lot of power. Which Palmer unit should I get?
Check the current draw (mA) of each pedal and add them up. Then, choose a Palmer unit with a higher current rating to provide headroom and prevent voltage sag. It's always better to have more power than you need.
