Bought this product to supplement a 5 string set to go on one of my fretted 6 strings (a 1992 Japanese Ibanez sr1306pd). Fitted last week, seems very well made, went into tune nicely with the normal amount of previous stretching. Intonation great across the entire fretboard. The tone is well balanced with the other Ernie Ball strings, puts a nice zing back into the bass. Stayed in tune well so far. I wouldn't hesitate buying pyramid strings in the future. Great prices and usual excellent service from Thomann, as per usual.
