Boss ME-50B (Bass Multiple Effects)

There are plenty of quirks of the ME-50B, I've owned mine for more than 5 years now.
Positives:

• Great Compression

I can never get enough of the great compression on the ME-50B, the options are limited but they get the job done.

• EQ-Settings are satisfactory:

Any modern EQ system usually have a minimum of four knobs (low, mid-low, mid-high and high) so that you can get all the tones you want, but with the ME-50B you only have three. BUT the cool thing is that you can change the mid freq. and adjust the level using the mid-knob... now that to me is pretty cool and you can use to get different tones with your distorted/over-driven bass and of course with your clean bass.

• There are some decent filters on there

Not really anything I can say about that, except that I wish I had more control over the filter-options

• No need for noise with the awesome noise-gate

This was a personal favorite feature of mine since I had a very crummy bass which made a lot of noise when plugged in, but when plugged in with the ME-50B, the sound was reduced to a very tolerable freq. you may lose some brightness though

• Battery powered

This is when you don't want a third cable coming out of your pedal, and you just want to simply rock with less constrictions. stumbling over your ME-50B won't lead to the whole performance collapsing because you tripped over the power chord, nope, not with a battery power back-up!

• The volume pedal does the job

I can't really say much more about that, it just does.

Personal Negatives:

• The low pass on the wah-effect is ridiculous:

Turn on the wah-pedal and bring it to a stand: you will get this very thick sound that usually kicks in the compressor on my bass amp because it was horribly made! I usually have to stick a piece of paper under the pedal so that I don't reach that peak of doom!

• The E-Level on the drive pedal is going to ruin your live performance if you don't check it before hand:

This E-level is going to rape your amps if you have blasted on full. Now I know one can simply not turn on the E-level knob to high, but if there was shifting going around that you were not aware of...
Take it from my experience, always double check that E-knob before you switch on the drive pedal on-stage.

• All the drive effects are poopie:

Some people like it but I hate them all... they just sound poopy to me.

• Octaver-effects do not work with more than one note:

Not only can you NOT play chords with the octaver on, but you have to make sure that your bass doesn't bleed as well!

• Delay/modulation are okay but with very limited modification

I think this is very self-explanatory

• YOU CAN NOT ADD MULTIPLE EFFECTS FROM THE SAME PEDAL!

This destroyed me! I couldn't add delay and reverb together! This becomes very quickly a nuisance

• Switching the knob mid session causes this horrible kill-switch action:

If you like to have a kill-switch on stage, then just turn any of the knobs and they'll do that for you... but if you are mid-song and you want to change the effect... you're going to have a bad time

• latency with the ocatver pedals

If you switch on the pedal and select an octaver option (+1/-1 octave) you're going to notice some latency

• If the battery is low on your pedal the only thing you'll see on the indicator is (b.b.b.b.b.b.b.b.b.b.b.b.b.b.b.b.b.b.b.b.b.):

I KNOW THE BATTERY IS LOW, PLEASE LET ME TUNE MY BASS THOUGH!!!! (this has happened way too often)

This is the best bass pedal I've ever played. I use it for fretted and fretless bass. Great overdrive tones. I love the octaver. Chorus and reverbs are superb. The preamp is clean and doesn't color the tone of my bass. Tuner is accurate and fast. This is the only outboard gear that I use.
