TC MojoMojo - bargain for bass

#61
^^^

I've owned the spark, mojo mojo, and the Blueberry Queen Bee, and liked them all but they all got replaced by a Dave Hall Valve pre DI so I'd recommend that if you can find one.

The Mojo Mojo's lowest gain sort of carries on from the Spark's highest gain, so having both is useful.

The Spark is similar to the Queen Bee's lower settings but not quite as dark and tube sounding, and the Mojo Mojo is similar to the Queen Bee's higher drive settings but a bit more raspy and synth sounding and a bit less complex.

If I was getting just one pedal I'd prefer the Queen Bee (or ideally the Queen Beest as mid control would be useful), but it costs more than both of the TCs combined and with those two you'd also have the advantage of individual footswitches for each + stacking them etc. so there's not much in it. I'd probably get both TCs.

Joined the Mojomojo ranks today, picking this one up used, nearby. I haven't had too much time with it, but the first impression is very, very positive. I was looking for a always/often on pedal, that adds a subtle bit of grit and filth to my signal, without amputating the bottom end. I think this little gem does just that mighty fine.

How’s it working for you? I just bought one for an “always on” grit and dirt tone, I was looking for a slightly dirty Motown sound to add to my P and Jazz basses to get away from the ultra clean tone of my amps...

Dark green: "Voice" switch UP
Light green: "Voice" switch DOWN

"Drive" knob at minimum, "Bass" and "Treble" knobs at their 12:00 detents. "Level" knob at approx unity (3:00).

Maybe it behaves differently at higher drive settings...

That’s funny even TC is confused in their documentations for the down position: The manual says bass frequencies are naturally boosted and the quick start says juicy tone that backs off the bass a little. But according to your test, the quick start doc seems to be more accurate...

This is a great pedal for the price.
the down position gives a subtle bass boost. it’s more noticeable with guitar.

i bought a mojo mojo used for $20 to try as a tone shaper with my guitar rig. too muddy for my tastes, so i put it on my bass board (most of my gigs are for bass) and i’ve been blown away with how great it sounds.

ising a 93 g&l legacy bass (now called the LB100) with flat wounds. the mono mojo is a great low gain overdrive that doesn’t cut or compress the bss sound. it’s nice and worked open. i also rin a dark glass alpha omicron for a modern distortion sound and an mxr m80 DI which has a nice compressed drive in it to give you the dead boys 78’ punk sound.
of all of em the mojo mojo was not only the cheapest but also the most usable and useful.

I've sold my big muff deluxe because the mojo mojo can get nearly as fuzzy but with a warmer sounding distortion that I prefer while still being able to keep the natural bass tone and sound like one instrument playing (I found blending the clean/distortion tone on the big muff and some other distortion pedals with blend sounds too much like two separate instruments playing at the same time). The mojo mojo doesn't destroy the bass tone but does lose a little bit low end thump with distortion turned up, I mostly use it dialed down for a nice subtle blues type warm sounding overdrive which retains most of the natural bass tone and thump.

It also works really well with an Aguilar Octamizer and/or MXR M82 before it.

There's no hiss or background noise and it hardly changes the sound at all with the Drive at zero so it can also be used as a volume boost and for tone adjustments. Only downside is an audible click when disengaging.

Can anyone tell any difference with the voice switch though? I'm not sure it actually does anything and it seems a few others can't either because the guide leaflet says 'true natural overdrive (up) or a juicy tone that backs off the bass a little (down)' but various reviews contradict that, sustain punch says 'Down position – Low-end frequencies are naturally boosted' and a professional youtube review says 'up position brightens your high mids'.

It's quite clear that there's a heavy high pass and low pass filters that's baked in to the pedal.

What this switch does is a mystery to me. But it's a great-sounding inexpensive overdrive, so I'm not going to hold that against it! :)

Looks like a -6db oct / slope at 220hz high pass, which is quite high. The Bass boost / cut looks set at 80 hz.
The Low pass filter looks quite steep, maybe -9db oct slope, set at around 7Khz.
This isn't a transparent pedal, but it's still very serviceable. For £40 UKP, it's a bit of steal.
This pedal could very easily be mimicked with a Source Audio Aftershock.
Every clipping circuit messes with the tone, typically boosting mids like a super wide Q, which is why we bassists often need bass & treble +/- controls. If you try a non buffered or filtered tube screamer then you will hear a huge spike in upper mids purely from the op-amp and clipping circuit. The only truly transparent analogue pedal I've seen / tried / owned is the Fairfield barbershop that uses just a pair of "jfet" transistors to clip.

Yep, it's not a transparent pedal. Not sure if there's a misunderstanding, but the posts you quoted were solely talking about the effect of the "Voice" switch on the output.

Hi MartinB, I'm not knockin the pedal, just trying to under stand it. Yes it's quite clear from those spectral plots that the "voice" switch is just a small gain stage. It's funny how a 3 db gain can make a guitar project in a mix and sound clearer...when in actually, it's just been given a wee boost.
Spectral plots always reveal a lot of information where distortion is concerned. It's nice to see where the Bass / Treble frequency centres are and where the high and low pass filters are placed. For bass, a 7Khz low pass filter works well as it cuts off a lot of noise and unwanted hiss...and lets face it...bass doesn't have much content over 8Khz. The high pass filter shelf seems to be set quite high at 220 hz. Combined with the 9db boost at 80 hz, it'll make the lower mids nice and solid too. But this pedal might sound a bit thin on a 5 string thundering the low frets.

Swapping my Mojomojo's stock diodes (SMD 1N4148 or similar) for a pair of red LEDs reduced the clipping and allows my Mojomojo to function as a clean boost. Using a P bass with rounds and setting the gain below noon, the pedal cleans up like never before. And it still gets substantial drive and clipping past noon.

I stumbled on this by accident, swapping to LEDs trying to get a grittier distortion. The swap did reduce the compression a bit and really opened the lowest gain clipping up.
