Carl Wolf Guitar. If you need any type of guitar repair, no matter how big or difficult the job is, you would do best to contact Haywire Guitars in Conway, SC. Rick Mariner is the founder of this great guitar repair shop and is friendly, courteous, and always attentive to the the customer’s needs and wants. Rick will always go the extra mile to make your guitar repair first rate and sound and play better than ever. He is also extraordinarily fast in turning around all repairs and is very quick to ship back to you. I can’t recommend this merchant enough for all guitar players/collectors.
