I have had my set now for roughly a month, or more. All I can say is that they are fantastic, I absolutely love them. I had an issue with junk tuning machines which lead me to buy replacements. I decided to take the plunge and purchase a set. I can say honestly, the difference it made in playability is remarkable. I can seriously do everything next to tear on the strings and they will remain in tune or damned close! Not to mention, they also look great! I owe a great deal to Bill Thompson (craftedcow),thank you sir! Anyone else have an opinion on Pegheds?
