Browse our collection of used Vox guitar amplifiers for sale, from AC15 and AC30 models to Custom Classic and Hand-Wired amps and other Vox designs from the 1980s to today. A used Vox AC15 or AC30 delivers the chime, harmonic richness, and touch-sensitive breakup of classic Class A British tone, at a price well below a vintage original.
At Mahar’s Vintage Guitars, every used Vox is inspected, tested, and documented before it ships. We photograph the chassis, speakers, and cosmetics up close, and we note service history, replaced parts, and modifications in every listing. Our inventory changes constantly, so check back often.

Buying Guide: What to Know Before You Buy a Used Vox Amp
Vox amp lines from the 1980s to today
Modern Vox amps are built around the same classic designs introduced in 1958 and 1959. The AC15 and AC30 remain the core of the lineup, with Class A circuits and EL84 power tubes, and they come in several versions: Custom Classic models, a Hand-Wired line with point-to-point construction, and smaller amps like the AC4 and AC10. Vox has also built other designs, including the Night Train and the Valvetronix modeling amps. Because the brand has been built under a succession of owners and in different factories since the 1980s, the model, series, and country of manufacture are worth checking on any used Vox.
What drives value in a used Vox
-
Model and line — Hand-Wired and Custom Classic amps, and AC30 models in particular, generally hold their value best.
-
Speakers — Celestion Greenbacks, Alnico Blues, and other speaker choices change the sound noticeably, and they’re one of the biggest factors in value.
-
Originality — original tubes, speakers, and electronics matter. Modifications can improve the sound for a player but usually reduce resale value.
-
Service history — fresh tubes and a recent technician check are valuable on any tube amp, and we note known service history in each listing.
-
Condition — clean cosmetics, quiet controls, and original covering and badges all add value.
How we inspect and test our amplifiers
Every amp in this collection is inspected and powered up in-house before listing. We check every control and channel, note tube condition and any modifications, and photograph the chassis, speakers, and cosmetics so you know exactly what you’re buying.
Frequently Asked Questions
What’s the difference between a Vox AC15 and an AC30?
The AC15 is a 15-watt amp, usually with a single 12-inch speaker, while the AC30 is a 30-watt amp, usually with two 12-inch speakers. The AC15 reaches its natural breakup at lower volumes, which suits smaller rooms and recording, and the AC30 has more headroom and projection for larger stages.
Do I need to bias a Vox AC30 when I replace the tubes?
Many AC15 and AC30 models use a cathode-biased design, which means there’s no bias adjustment when you replace the EL84 tubes. Designs and versions vary, so confirm with a qualified technician if you’re not sure, and we’re happy to help.
What speakers do Vox amps use?
It depends on the model. Many AC30 and AC15 amps use Celestion speakers such as the Greenback or the Alnico Blue, which are known for a chimey, responsive sound. We note the speakers in every listing.
Do you ship amplifiers, and how are they packed?
Yes, we ship amplifiers nationwide and internationally, with careful attention to packing given the weight of the amp and the fragility of the tubes. Every amp is insured in transit. Import duties and taxes for international orders are the buyer’s responsibility and vary by destination country.
Can I trade my current amp toward a used Vox?
Yes, we accept trades toward amplifiers in our inventory, including full collections. Reach out with details and photos of your amp and we’ll provide a trade valuation.
