www.nevadamusic.co.uk Full of all the usual effects used by the electric guitar player, the ME20 is a very versatile unit with the same high standard of sounds synonymous with Boss effects. Taking advantage of the years of experience Boss has with stomp box effects, the ME20 is a culmination of all these separate effects in one easy-to-transport box. Each effect can be edited to your own personal taste via the five control knobs, which act in the same way as the control knobs on the single stomp box models, making this the ultimate box combo. Live Performance Pedals The ME20 has been optimised with the live musician in mind. There are three footswitches which breakdown into separate effects, the first footswitch controls the overdrive and distortion and gives you the option to switch between different types of overdrive and distortion. The next footswitch controls modulation effects such as flanger, phaser and tremolo. Once the desired effect has been selected then these footswitches simply turn the effect on and off. The third footswitch controls delay and gives you the option of two different types of delay or reverb. These three footswitches become the stomp box once you have assigned them to an effect so you can switch them on and off as you would a singular effects pedal. Also featured on the unit is an expression pedal which controls the wah effects.
