How to choose the best guitar effect power supplies
Reliability
EHX power supplies are known for their consistent output, even with multiple power-hungry pedals. This means less downtime during gigs and fewer headaches in the studio - a flat-out essential.
Noise/Hum Reduction
EHX designs often incorporate features to minimize noise and hum, which is critical when you're trying to capture a clean, articulate tone. Less noise means more headroom to push your drive pedals without unwanted artifacts.
Voltage Regulation
Consistent voltage is the key to pedal stability. Fluctuations can cause erratic behavior or even damage your gear. EHX generally delivers a stable voltage, even when multiple pedals are drawing significant current.
Current Capacity
Don't underestimate this. A weak power supply will lead to dropouts and weird noises. EHX offers a range of options to handle everything from a small board to a monster rig.
Simplicity
EHX power supplies prioritize function over flash. You're paying for reliability and performance, not a bunch of unnecessary features you'll never use. This simplicity also makes troubleshooting easier.
Buying guide
Look, powering your pedalboard can be a real headache. You've probably dealt with the hum, the voltage drops, the inconsistent performance - it's a drag. Electro Harmonix has been around long enough to know that a flaky power supply can ruin even the best fuzz tone, and they've built a reputation for reliable, straightforward power solutions that let your pedals do what they're supposed to do.
Honestly, you're getting a solid value with Electro Harmonix. Their power supplies aren't the absolute cheapest out there, but they're not breaking the bank either. Watch out for generic knock-offs - those often cut corners on components, leading to instability and potential damage.
Spend a little more for the peace of mind; a reliable power supply is insurance against pedal failure on stage.

Questions
Are Electro Harmonix power supplies isolated?
Most modern EHX power supplies are isolated, meaning the AC lines are separated. This helps prevent ground loops and reduces noise - a big plus for pedalboards with multiple amps and effects.
What's the difference between the Lil' Surveyor and the Surveyor?
The Lil' Surveyor is a smaller, more compact option with fewer outputs, ideal for smaller pedalboards. The Surveyor is the full-size version, offering more power and output options for larger rigs.
Can I use an EHX power supply with my vintage pedals?
Generally, yes. Most EHX supplies provide a stable 9V DC, which is what most pedals need. Just double-check the voltage requirements of your specific vintage pedals to be sure.
What about noise when using a power conditioner?
Sometimes, power conditioners can introduce noise if they're not compatible. Experiment with the conditioner's settings or try bypassing it entirely to see if it improves the signal. It's not always a straightforward improvement.
Do I need a voltage converter if I'm traveling internationally?
Absolutely. Check the voltage requirements of your power supply (usually 120V for the US and 230V for Europe) and use a step-down or step-up converter as needed. Failing to do so can fry your gear.
