Why the Original Power Supply Makes Your Pedal Worth More

You can sell your boutique pedal with the original power supply, or without it — and that choice is worth more money than most players expect.

The fork nobody mentions at listing time

The gap between "complete" and "power supply not included" isn't a small rounding error. On boutique pedals — think Strymon, Chase Bliss, Earthquaker Devices — a missing original supply can drop the asking price by fifteen to thirty dollars on the low end, and by fifty or more on a high-demand unit. The buyer on the other end of that listing knows exactly what a replacement costs. They subtract it before they make an offer.

Why a power supply isn't just a cable

Most effects pedals are fussier about power than guitarists realize. A boutique overdrive that wants 9V center-negative at 100mA will work fine on a standard supply. But a digital reverb or modulation pedal from Strymon, for instance, often requires 9V at 300mA or higher — and running it underpowered causes glitches, noise, or silent failure. The original supply is spec-matched at the factory. A random replacement might fit the jack and still damage the circuit over time. Buyers know this. So when the original supply is in the box, they're not paying for a cable. They're paying for certainty.

What tips the decision toward keeping it together

The pedal and its supply are most valuable as a unit when the pedal has unusual power requirements. Anything digital — multi-effects, reverbs, delays with tap tempo, loopers — almost always falls into this category. The original supply for a Chase Bliss Audio pedal, for example, is a specific 9V 500mA regulated adapter that the company recommends by name. Selling without it hands the buyer a research project. Path A, selling complete, removes that friction entirely and commands a stronger price without negotiation.

Path B, selling the pedal alone, makes sense only if the supply is a genuinely generic spec — 9V center-negative at a standard milliamp draw — that any pedalboard power brick already covers. A basic analog fuzz or a simple boost pedal running at 9V 30mA? A missing supply barely moves the needle. The buyer already has four of them in a drawer.

When exceptions flip the math

A scratchy pot on a boutique pedal with a complete power supply still tanks the value — the supply doesn't rescue a broken unit. Physical condition and full function matter more than any accessory. If you're selling a pedal with a knob that scratches or a footswitch that intermittently cuts out, fix it or price it honestly before worrying about the supply.

The other exception is collectibility. A rare, discontinued pedal in high demand — the kind that shows up on Reverb with a dozen watchers — attracts buyers who will pay market price regardless of whether the supply is included, because they want the pedal badly enough to source the adapter themselves. For that narrow category, the supply adds value but doesn't make or break the sale.

The counter at A-1 Trade & Loan on Commercial Drive sees the same math play out in person — a pedal that arrives complete simply has fewer questions attached to it.

How to pick your path

The decision comes down to two quick checks. First, look up your pedal's power spec on the manufacturer's website or the back panel. If it draws more than 100mA, or if it specifies regulated or isolated power, the original supply is worth real money to the next owner — keep it with the pedal. Second, search your exact model on Reverb under "sold listings" and compare completed sales with and without the supply. The price gap will tell you exactly what it's worth in your hand versus in a box.

Plug the pedal in, confirm it works, then check Reverb sold prices for your specific model — complete versus incomplete — and the right path will be obvious in under two minutes.
