If you're looking to sell guitars on the Collings Forum (specifically for Collings, Waterloo, or related high-end acoustic/electric instruments), here’s a step-by-step guide and some best practices to do it effectively and respectfully:

1. Register on the Forum

Create an account if you haven’t already.
Be sure to read the forum rules, especially for the Classifieds section.

Navigate to the Classifieds section.
Choose the appropriate subcategory (e.g., Acoustics for Sale, Electrics for Sale, etc.).
Click “New Topic” to create your listing.

Photos Help Sell
Include clear, well-lit images of the front, back, sides, neck, headstock, and any blemishes.
Use Imgur or a similar hosting site if the forum doesn’t allow direct uploads.

Be Honest and Transparent
Clearly describe any imperfections or repairs.
Be upfront about shipping costs, payment methods, and return policies (if any).

Follow Up
Mark the item as SOLD when it’s gone.
Thank interested buyers and keep communication professional.

Avoid These Mistakes
Posting without photos or a price.
Not responding to PMs or inquiries.
Bumping your ad too frequently (check forum rules on bumping).
If you'd like, I can help draft your ad or even format a listing if you give me the guitar details.
