✅ Item Condition & Testing

All used gear is fully tested when it comes into our shop and again before shipping, so you can buy with confidence. Any included accessories will be shown in the photos, and if there are any functional issues, they’ll always be noted in the listing. Since these are used items, you can expect normal cosmetic wear that doesn’t always show up clearly in pictures. Everything we sell is also available to try in-store, so a little extra demo wear may be present.

? Shipping Info

We ship to the contiguous 48 states with flat-rate pricing that usually covers the maximum cost (including insurance). If the shipping looks high, send us your ZIP and we’ll get you a more accurate estimate. Orders outside the lower 48 may require additional processing and shipping costs — please reach out before ordering.

Some larger or fragile items (like big amps, drum kits, or cabs) may not have a shipping option listed because they’re safest for local pickup. If you’re not sure, just contact us and we’ll confirm if it can be shipped.

↩️ Returns

You have 48 hours from delivery to let us know if you’d like to return an item. Buyer covers return shipping, and a 20% restocking fee applies per store policy. If you’re unsure about an item, feel free to message us first — we’re happy to answer questions and make sure you’re confident before purchasing.

? Order Issues

If your order isn’t going through, check that your billing and shipping addresses match — that’s the most common issue. If you run into any problems, reach out and we’ll help you get it sorted.
