Monel has been around since the early 1900’s and consists of 67% Pure Nickel, 30% Copper, 3% of the magic juice that contains magnesium, zinc and other elements making Monel resistant to salt water (sweat). Monel also has a very unique “earthy” tone and is used on both acoustics and electric instruments. It has built in natural resistance to tarnish and corrosion yet it feels great to the touch and has its own unique tonal color. Monel provides a very rich tone on the neck pickup and this great little growl on the bridge pick up. For acoustic instruments it seems to bring out more the wood sound. This set has a hex Core and gauges are 13-17-26w-36-46-56. This gauging is perfect for most players wanting lots of volume and doing the down tuning on the A and low E.  Here's a video showing the tonal differences between some of the alloys that we offer including Monel.
