About this deal
Just used this pedal for the first time at a gig, it beats carrying around a heavy case full of individual pedals, and has a lot of great new features that i didnt have before, even with a delay, chorus, distortion and reverb pedal, i wont be looking back. In the ME-50 there was often a noticeable lag which made it a show stopper when playing live, for some people. The quality of the effects can vary, some distortions are not as crisp or dynamic as their BOSS stompbox counterparts (which weren't exactly premium grade to begin with), and some effects you would like to be separate from others, whereas they are unfortunately confined to the same pedal.
The Overdrive/Distortion section adds the aforementioned Boost and Natural to a range of gritty effects from overdrive to fuzz.In Pedalboard mode the same external switches will let you switch the Preamp section and Reverb on and off. Often a device requires that you step on two footswitches at one time to turn on a tuner, enter bypass, and with the ME-70, for example, access Memory mode and the Bank up and down option. These musicians could afford the more complex, larger pedals from the Boss GT series, but seem to find that the compact, lighter-weight, simpler to use ME line gets the job done—hogging less cargo and stage real estate in the process. I'll be interested in hearing the opinions of some of our other Tone-Masters about how the sound stacks up, especially that Mesa/Boogie setting.
When you turn the knob to change the value, it can either change immediately from it's current position regardless of the previously saved position, OR you can do it as in the ME-50 and many other devices like this. The ME-70 gives you most of Boss's popular effects, plus quality amp modeling, and a wah pedal with decent sound quality. The Boss ME-70 is a guitar effect pedal with dedicated knobs for each parameter that allows you to get the perfect effect or series of effects easily and quickly.
There is less definition with distortion as there are more overtones created because of the hard clipping. That said, these nut jobs would not confine their overdubs to effects that I had available as analog standalone units (and I had a variety of echoes, choruses, phasers, flangers, etc in both stompbox and rackmount formats that were all really nice even by today's standards). However, the ME-70 now splits some of those tone options off to the new Preamp section, which makes sense since some of the OD/DS choices on the ME-50 were amp-specific distortions.
