yes, thanks for the input. I have played around with tuning them, along with one of the other artist in the shop. He helped me tune it as well. And i can get the machine running nice, but then it starts to sound funny and have a follow through issue. Its really weird how sometimes it runs like a champ and then ill set up for another tattoo, (same needle configuration) and it will run completely different. I run a CX-2 power supply which i know is good, and none of my other machines do this so i know its not in the clipcord. Im just very perplexed because I know how good the machines are. I just cant get it to be consistent. Thanks for any input, I know the best thing to do is contact Next Gen, I just wanted others opinions first. Thanks a lot.
