The Hidden Cost of 9V Batteries: Vintage Guitar Pedals, Modern Pedalboards, and a Smarter Solution

Even with the rise and widespread availability of 9V power supplies, many guitar players' pedalboards still rely on the humble battery to chase tone with some of the most popular vintage classics and modern stomp boxes. For those pedals — built without an external power jack and designed to run on battery only — the 9V cell remains the sole option, and its costs and inconveniences are easy to overlook.

A Brief History of the 9V Battery Price

A documented example from 1980 shows an Eveready General Purpose 9V battery with a retail price of $1.72. Today, major-brand alkaline 9V batteries commonly sell for roughly $2.50 to $5.00 each, while premium lithium versions can cost considerably more. That's a meaningful price increase over four decades — and it adds up for active players.

Battery-Only Pedals: A Real Category

While most modern pedals include a standard 9V DC power jack, a significant number of vintage designs — and even some contemporary stomp boxes — were built without one. For players running these on a pedalboard, forgotten replacements before a gig or a dead battery mid-set aren't just inconvenient, they're an ongoing cost with no endpoint.

The Real Cost of Battery Replacement

A well-used battery-only pedal might go through two to three 9V batteries per year. At $4 per battery, that's roughly $8–$12 per pedal annually. For players running multiple battery-only pedals:

• 1 pedal: ~$8–$12/year
• 3 pedals: ~$24–$36/year
• 5 pedals: ~$40–$60/year

Lithium batteries cost considerably more, but are sometimes preferred for low-current vintage circuits — making the annual cost even higher for some players.

The Vintage Pedal Preservation Problem

Many vintage pedals were never designed with modern power supplies in mind. Collectors and players alike often hesitate to drill holes or permanently modify valuable vintage enclosures — and rightfully so. A drilled enclosure is a modified enclosure, and that can meaningfully affect both tone and collector value.

The challenge: how do you bring a battery-only vintage pedal into a modern powered pedalboard setup without compromising its originality?

Battery Eliminators: A Practical Alternative

Battery eliminators fit inside the battery compartment in place of the 9V cell, with a wire exiting through the existing battery door opening to connect to an external power supply. No drilling. No permanent modification. No ongoing battery purchases.

The PowerPlay No-Drill 9V Adapter from Small Axe Music is purpose-built for exactly this application — fitting inside the battery cavity and routing power from your pedalboard supply while preserving the originality of the enclosure.

Current PowerPlay adapters are available for a range of vintage pedals, including:

• MXR Vintage Late 1970s Block and Script Logo pedals
• MXR 1970s Script Logo Bud Box & MXR Case (MXR 101-2004-1)
• 1970s Crybaby and Vox V847 Wah
• Dunlop Fuzz Face (Silicon version)
• MXR '74 Vintage Phase 90 (CSP026) Script Logo Reissue
• Late 1970s MXR Block Logo Small Case pedals
• MXR Vintage Phase 100 (Block and Script Logo)

A no-drill battery elimination solution can reduce recurring costs, modernize battery-only pedals for powered pedalboard use, and help preserve instruments worth protecting. Learn more at smallaxemusic.com.
