FAQS

1. Do you stock original brand parts?

Yes.

At Hardcastle Guitar Supply we only source from trusted, official suppliers and manufacturers such as Gotoh, Switchcraft, CTS, and other well-known brands. Every item we sell is guaranteed 100% authentic, brand new, and inspected before shipping. We do not sell imitations, knock-offs, or second-hand parts unless clearly stated in the product description (e.g. clearance, B-stock).

2. Do you ship internationally?

Yes, we ship worldwide.

  • South Africa: Local orders are shipped via trusted courier partners and typically arrive within 2–5 business days.
  • International: Delivery times vary depending on destination and customs, usually 7–21 business days.
  • Customs Duties/Taxes: Please note, some countries may charge additional import duties or taxes. These charges are not included in our prices and are the responsibility of the buyer.

If you’re unsure about shipping costs to your country, contact us before placing your order and we’ll provide an estimate.

3. How can I track my order?

Once your order has been dispatched, you’ll receive an email confirmation with a tracking number. You can use this number to track your package through the courier’s website.

  • Local orders: Updates are usually available within a few hours after dispatch.
  • International orders: Tracking may take 24–48 hours to appear, and in some cases, updates may pause while your parcel is in customs.

If you experience any delays or issues, email us at info@thehardcastleco.co.za and we’ll assist right away.

4. Can I return or exchange an item?

Yes.

We understand that sometimes a part may not fit your guitar, or you may change your mind. Our Returns & Exchanges Policy allows you to return or exchange items within 14 days of delivery, provided they are unused, in their original packaging, and in resellable condition.

  • If the item is defective, damaged, or incorrect, we will cover return shipping costs.

  • For Gotoh, Switchcraft, and CTS parts, warranties are typically 6–12 months.
  • Strings, picks, and consumables are not covered under warranty due to natural wear.

If you experience a warranty issue, please contact us with photos/videos and proof of purchase.

7. Can you help me choose the right part?

Absolutely!

If you’re unsure whether a part will fit your guitar (e.g. tuner hole size, bridge spacing, or potentiometer type), email us with your guitar’s make, model, and year. Our team will help guide you toward the correct fit.

Yes, we support builders and repair shops. If you are ordering in bulk or regularly purchase parts for repairs/builds, contact us at info@thehardcastleco.co.za to discuss wholesale or loyalty pricing.
