Guitar Effect Power Supplies by the numbers
Measured across all 189 models in this category, so «wide», «short» or «expensive» mean something you can check.
How to Choose the Best Guitar Effect Power Supplies
Current per Output
This isn't just about wattage; it's about clean, stable current. Pedals, especially fuzzes and distortion, draw a lot, and starving them leads to flubby low-end, loss of sustain, and a general lack of clarity. Aim for at least 300mA per pedal, more for those hungry overdrives.
Ripple & Noise
This is the invisible killer. High ripple creates a subtle hum or hiss, and can mask your signal. Good power supplies filter this out, giving you a cleaner, more defined tone - crucial when you're trying to dial in that specific breakup.
Isolated Outputs
This is a big one. Isolation prevents interactions between pedals - your tremolo shouldn't be affecting your reverb's decay time. It's about maintaining the integrity of each effect's character.
Form Factor & Space
Pedalboards are precious real estate. A bulky power supply eats up space you could be using for more fuzz. Consider the size and layout, especially if you're building a compact board for gigs.
Protection Features
Short-circuit, over-current, and reverse-polarity protection are all vital. They're not just marketing fluff; they protect your pedals and the power supply itself from catastrophic failure - a lifesaver in a chaotic rehearsal setting.
Buying Guide
At your level, you're looking for reliability and clean power, not necessarily a million features. Don't fall for the bells and whistles - those extra outputs you'll never use just add cost and potential points of failure. Watch out for those super-cheap units; they often cut corners on filtering and isolation, and you'll pay for it in noise and inconsistent performance. Spending a bit more on a reputable brand with isolated outputs is a worthwhile investment.
How This List Is Built
We don't play these instruments — we're a catalog, not a review desk, and we'd rather say so than pretend otherwise. This page covers 189 guitar effect power supplies from the Thomann catalogue, which is the largest single source of specification data in this category: 15 in detail, the rest listed with their specifications.
Position is computed, not curated. We parse the manufacturer's own description into actual values — nut width, scale, fret count, fingerboard radius, size, alloy — and rank on them: how many specifications a model has published, how many of them are measurable numbers, and how precisely it meets this page's criterion. A product image adds a little. Price is not a ranking signal: it tells you nothing about whether a neck fits your hand. The same inputs always produce the same order, so nothing here is shuffled to look fresh.
What this list is good for: narrowing a category down to a shortlist by spec and budget. What it isn't: a substitute for hearing an instrument. Before you buy, read hands-on reviews and, where you can, play it. Full methodology.
