"Bumped" Sets

What the heck is a "Bumped" set?

A bumped set, simply, is a custom set of strings with SUPER-light tension.

It is traditionally created by substituting a string designed for a higher pitch for each string on your bass; commonly, this means using an A-string for the E, a D-string for the A, a G-string for the D, and a High C-string for the G. Thus, you're "bumping" each string down one position on your bass, but - and this is the key - you're still tuning it E-A-D-G.

Wow - that sounds like the strings would be really light, doesn't it? Why would anyone do this?

When it comes to rockabilly bass playing, sometimes ease of play is paramount. Many players find that standard string sets are just way too stiff to play 3+ hours of non-stop slap bass on. Thus, a bumped set can be a happy medium between the extremes of higher-tension "real" upright bass strings, and the tonal compromise of putting weed-whacker line on your bass (no, seriously).

Previously, "bumping" a set might require that you purchase a whole set (plus a high C) -- and you end up paying for an unused E string that gets thrown in a drawer somewhere in the bass den. So we've put together some popular bumped sets to help you out.
