Guitar Effect Power Supplies by the numbers
Measured across all 188 models in this category, so «wide», «short» or «expensive» mean something you can check.
How to Choose the Best Guitar Effect Power Supplies
Isolated Outputs
Crucial for minimizing noise and hum. Shared power rails can create a muddy, undefined low-end-especially with fuzz and distortion pedals. Isolation keeps things clean and allows your drive pedals to really articulate.
Current per Output
Make sure it matches your pedals' needs. A vintage Tube Screamer needs less juice than a modern, high-gain overdrive. Undersupply can lead to erratic behavior and weird noises; oversupply is generally safe but a waste of power.
Noise Floor
A quiet power supply is a good power supply. Even a tiny bit of noise gets amplified through your effects chain. We're listening for that subtle hiss or buzz that can ruin a clean tone or mask your pick attack.
Form Factor & Cable Length
Consider your pedalboard layout. Short cables are fine for a small board, but longer cables are a must for larger setups. A compact form factor helps save space, too.
Regulation
Consistent voltage is key for stable pedal operation. A power supply that fluctuates voltage under load can cause tone inconsistencies and potentially damage your pedals over time.
Buying Guide
In this price range, you're making trade-offs. Don't expect fully isolated outputs on every single channel of a super-compact unit - that's usually a $400+ feature. Look for a good balance of isolated vs. shared outputs and prioritize enough current per pedal. A solid, reliable power supply is more important than flashy features; it's the silent workhorse of your rig.
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 188 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.
