GHS BIG Core Bass Roundwound Electric Bass Strings Medium 45-105 Ever since I first heard about these strings, I've wanted to try a set, and I'm damn glad I did! As you might suspect, these strings have a larger hex core. How much larger I don't know. GHS claims "the larger core wire supplies note definition and focus while still maintaining excellent feel". They are wraped in a proprietary nickel iron alloy. The .105 E string is taper wound and GHS has this to say "it is this taper design that increases fundamental bass note accuracy, adds sustain and tone life and insures outstanding E string performance past the fifth fret". String Tension: G=44.7 D=50.2 A=49.3 E=40.8 Total stringset tension=185 pounds. This is quite good and a roughly 10 pound spread is balanced enough as the proof is in the playing. String-To-String Consistancy: For both tone and volume is excellent & exceedingly well balanced! Most certianly among the very best, if not the best that I've ever played. Folks, this is high praise indeed, as I am damned persnickety. Tone: Clear & Well Defined Top-To-Bottom. The taper wound E string is pure unadulterated magic! I don't think I've ever heard a better sounding roundwound E. The extreme clarity & definition of the open E is astounding. Here we have a nice thick full well defined bottom with a deep clear growl unmatched by any other stringset. As much as I loved the taper wound E's of Fender's 8250M, and D'Addario's EXL-170BT sets, I am easily convinced the GHS is the best. The midrange is very solid beefy/meaty with good low-mid growl, and plenty snarl in the high-mids. Excellent even well defined/focused tone throughout. No mud or honk to be found here. Highs for days! Smooth & Soaring, but never harsh or overbearing. Has good bark & bite when picked. Plenty of spank when popped. Feel & Playability: I like the feel of the nickel-iron alloy wrap. I can't tell any difference from nickel plated stainless, which I also like. String-to-string feel is very even, and you don't really feel any differences in tension. Takes more effort to bend than the D'Addario Balanced Tension, but overall the playability is still quite excellent, and among the very best. Overview: I think you can tell I really like this stringset and am damn glad to have them on my Fender Jazz bass. They sound absolutely fabulous, and this may well become my roundound set of choice just as GHS Precision Flats have become my flat of choice. I will come back with updates each month until I post the obituary.
