The Boss ME-25 multi-effects pedal provides a collection of additional sounds and features over the previous ME unit at the same price. This Boss guitar pedal includes a completely redesigned operating system which allows the entire product to operate in "EZ-Tone" mode, making the Boss ME-25 simple to use. There are added effects, COSM amp models, and a USB port for direct connection to computers. The ME-25 effects pedal is bundled with Cakewalk Sonar 8 LE and a DVD providing over one hundred audio loops that can be imported into Sonar for jamming or practice. The Boss ME-25's 60 onboard programs are organized into a Sound Library, which enables all the onboard tones to be selected simply by type. This built-in sound library gives you instant access to dozens of classic and modern effects. Simply choose a category, select a variation and play. You can customize your sound with simple twists of the Drive, Tone, and Volume knobs. .
