I went to the HQ today and had 3 of my juliets tuned up but apparently they're not as tight as the others I brought in a few months ago. what im talking about is that the couplers are soft. is it just me or they probably used a different compound for the couplers? the good thing is, the guy i talked to only made me pay 1 tune up for all the 3 juliets. does anyone here got a pair of x metal tuned up lately?
