tc electronic Spark Booster

I remember when that pedal cost 3 times as much, so once I saw this price drop I purchased one. It promises 20 db of clean boost but it is not like the mini spark. At the "clean" setting you have to increase the gain to get those 20db, which adds some distortion of the pedal. With the gain at 0 it only rises the volume at about 3-4 db (I m only guessing, in any case very little). At the other settings, the mid can do the ts thing by dropping the bass knob almost at 0, while the fat setting well it seems it's working as the mojomojo, but with much less gain, though it can totally work as a light overdrive.
What I don't like is that it keeps this "airy" quality, in every setting and I have to reduce the treble to get rid of it, but like that the mid setting doesn't get aggressive enough. It works fine but not quite as good as a ts.
So if you plan to use it in front of the amp, you get 3-ish- pedals at one. None of these modes though are as good as the equivalent pedal. If you need it for the fx loop for a solo boost, I suggest the mini spark. For the price it's a 6 star pedal, but price aside, well it's not amazing

Great value for the money!

I use it at the beginning of my chain.
A very versatile booster, which can color the sound or not depending on how you set it.
Useful by itself or to push an existing overdrive.
It can emphasize and give life to an amplifier with a slightly dead sound.
The three clean fat and mid options are quite useful, and have totally different voices.
This boost can go from a totally clean and crystal clear sound to a moderate saturation, which makes this pedal much more than a simple clean boost.
This is a good alternative to other boost pedals much more expensive, and less versatile.
My only complaints are the switch, which feels not very robust , and the volume disparity between the different modes.
Overall, a positive evaluation.

I was looking for something to go at the end of my pedals, for when I wanted a bit more of a volume boost. I wasn't initially looking to affect the tone at all, and considered the smaller, stripped down one of these.

However, the extra tonal switches and knobs piqued my curiousity and I ordered this one.

It sounds really good, and does a lot of things. You can use it as an overdrive, absolutely - and there was a time this would have been exactly the sound I was looking for.

I use it now as a ridiculous dose of clean boost for certain parts, and it works wonderfully for that. The tonal varieties are useful here too, more than I expected. The bass, treble and mid shift frequencies and curves are just right to my ear.

The one downside is that it is bigger than I thought, something about the shape and size takes up more real estate than I would like. That has a lot to do with my specific old pedalboard which has its quirks with its size. So its not really a bad point, but something to look out for.

I Bought this pedal with the intention of using it as a boost to my overdrive. It has a really nice gain control and with the combination of EQ you can achieve some great tones.
I have tried the pedal just by itself as well, and it didn't sound as convincing, so i would suggest to put it in front of a nice overdrive.
Also as a little downside.. the battery is not included.. where in majority of stomp boxes it is.
Overall ... The pedal is well made. it looks great on the board.. it does it's job as it should, and really thickens up the sound of the amp, also for this price.. you really can't go wrong.
I would definitely recommend this product to its future users..
