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.

Nice booster with eq
Ozeb, 07.04.2020
I use this booster to boost my '72 Marshall superbass with a bit of added dirt that pedal offers as well as for boosting my Marshall DSL 100 hr.
The EQ and the three modes it offers can make this pedal really versitile for many applications. I play mostly hard rock, and with my superbass, which is a bass amp, it comes in handy the use of EQ, as I can nicely shave some of the bass off while I'm pushing the amp. It comes in handy as treble booster too. It is nice for boosting solos as well, with the mid boost setting. It can be kinda tubescreamer - isch, but with different flavor. I use this setting with my DSL for adding midrange and make solos sing.
If you are careful with level knob, it can nicely boost overdrive / distortion pedals as well. I used it in front of my vintage, the original, marshall guv'nor, and it worked nicely. It is also pretty quiet, studio use was absolutely no issue.
It really don't have any cons, it's built to last and sounds wonderful. It's just the matter of taste, as all things sound conserning. It fits my needs, it probably will yours too.

Better than I thought!!
Jazzedout, 23.04.2020
I love TC Electronic products, bever bought anything bad from them!
I bought this to use as a slight boost when changing guitars from humbuckers to my Strat in order to keep the levels the same! Works great as a clean boost, but I am also trying to discover the more features that it has!!

Compact Pedal Packed With Features
peterpaul, 03.12.2013
I had been looking for a good booster to add to my pedalboard, but I wanted a booster which could give you something more, that something extra which you will find useful in particular situations. This TC Electronic Spark Booster is just that thing: an excellent clean booster, but at the same time it can be used to add dirt to your signal, pushing other pedals and the amp that little bit more.

You can tell that there was a lot of thought behind this booster. As regards dimensions, it's a very compact pedal and therefore doesn't take up much space on your pedalboard. There's no way you can forget this pedal on after you're done with your solo as the LED is very bright, insanely bright. Build quality is top notch, knobs and switches have that solid feel and the housing looks like it's really durable.

Battery compartment is easliy accessible by unscrewing the lid with a small coin, but I prefer to power it through the 9V barrel connection. Powered using a Voodoo Lab Pedal Power, I must say that the TC Electronic Booster is exceptionally clean, no hiss or hum or anything else, just the guitar's tone boosted to your liking. And it can be boosted up to 26dB, much more than what's needed to make your solo cut through the mix.

The Gain section can be used to act like an overdrive pedal. You will not get any distortion out of it, but some good overdrive quite similar to a vintage tube amp. I found this very useful. In other words it's basically another overdrive pedal on my pedalboard.

The Bass and Treble knobs proved to be very functional, especially when using different guitars with different tonewoods and pickups. No matter what I plugged into this booster, I easily managed to get a well balanced tone. To further enhance the EQ section, TC Electronic put a little toggle switch which will shift this pedal in three different modes. All three modes are distinct and pretty useful.

In a nutshell, this little pedal is packed with features: excellent clean tone (and plenty of it), useful overdrive, sensitive EQ, three different modes, true bypass, and bright LED, all housed in a very solid construction. What more could I want?
