This was my first pedal.

This thing is perfect to figure out what you like effectwise, but kind of useless in every other aspect.

Useable sounds: 1. Distortions are okay 2. "my first envelope filter" 3. "Phaser"

Unusable sounds: Everything else.

Major drawbacks: 1. The wah has a HUGE volume spike when you sweep it through the middle. 2. The synth's tracking is pretty much nonexistent. You have a choice of whole notes or halfnotes. 3. Octaver doesn't track well either.

tl:dr It's a decent pedalboard to start, but buy it used.

Had the ME-25, even less tweakable, but utterly hopeless effects!

Been using it for 15 years, still like it.

Been using it for 15 years, still like it. I use it as 3 different pedals + expression pedal (mostly as volume), never in meory mode.

A professional all in one unit!

A Bass Player's Dream Come True. Effects can be edited using 23 knobs and controlled via three built-in footswitches and an assignable expression pedal. This is the piece no bass player should be without!

Muito legal/ Very nice :)

Gosto dos timbres dela e o que me agrada muito é ela ter os knobs pra facilitar a regulagem. I like the tone of me50 and the best thing for me are the knobs that make my life easier.
