Kester 24-6040-0053 Solder Roll, 66 Core Size, 0.050 Diameter

very good product

Great for doing guitar/bass electronics!

Good product, fast shipping.

Best solder ever invented

Best tinning for guitar pots and wiring.

All were great.

Its lead based solder, not as sexy as 63/37 but its Kester.

Good! The right diameter, works well. I first bought a roll of .031 and it was too thin for the soldering I do (coax connectors, 14 or 16 ga wires, etc.) This size is much better. The .031 might be the right choice for circuit board work.

It worke flawlessly, a fantastic product.

The best thickness for 95% of the work. I am an engineer, certified for soldered connection on maned space flight. By this solder.
