I am so happy to have found these strings, as with the regular 7 string scale (25.5) you really can't get that tight bottom response with regular string gauges from other brands. That is, if you wish to set your action considerably low. The 64 thickness is perfect if you still wish to drop tune your low B to A. THe sound is nice, clear and bright, they last a long time if you clean them propperly and the tension feels not too tight, so you can still do your bending. A perfect string set for me, i'd reccomend them to anyone looking to reduce a bit of string buzz when using lower action.
