The best clean boost!

What to say? It's the best clean boost ever. Get the volume higher without coloring the sound. There's too much volume in this little box, I use it at 9h for solos. Great one and saves your board a lot of space!

Nothing to dislike here

This small pedal can add up to 20 dBs of gain. It's so powerful I can't imagine anyone using it above noon. Set just above 9 and in front of my dirt pedal, it's already nringing à good kick. People say that boost after dirt is for volume and before is for distortion but it is not completely true. I guess it dépends on how you set the dirt pedal and whether it has a lot of headroom but I can say that with my current senting both volume and gain are booster. It's not transparent as it brings some sparkle but for me it's a good thing. I guess you could set it at almost minimum and it would still bring something, like a good buffer.

The best little secret

How can something so cheap provide so much joy? 1.- It's tiny, so it doesn't get much space on your pedal board. 2.- Respects 100% the tone of your guitar and it's true bypass 3.- It has PLENTY of output (I never pass mine beyond 9 o'clock). 4.- Use it for leads, to push your amp, to balance different outputs when changing guitars live (single coils vs humbuckers, for instance)...It will do the job and won't let you down. 5.- It has a great "hold" feature. Step on it and leave your foot on to boost a riff and lift to go back to your volume. It can also turn on and off the traditional way, but this is a great way to boost a few notes without having to turn it on and back off again. I've had other boosters and sold them all. This one is a keeper for sure!

Booster + buffer

I keep this pedal always on at the start of the effects chain; in this setup, it functions as a high quality buffer. It also really helps push overdrive/distortion/fuzz pedals and the tube preamp when the volume is above 0.

When it's on, it also adds a little sparkle to the sound by boosting mid-high frequences. I generally like that, although, it would be better if I could choose. The same thing with the buffer: I wish I could switch to true bypass when I need it.

Great, affordable clean booster!

It might not have as much mojo as other boosters like Xotic EP Booster, but it is still a great pedal to have in your set up! I use it primarily as a front-end boost to give my amps more saturation, sustain, brightness and juice. It's perfect for all leads, solos and parts where you want to shine in the mix! Oh, and just to mention - I got mine for 29,99 USD brand new :)

Small but Mighty

The Spark Mini Booster is simple, affordable, and boutique, offering 20 db of power in an analog circuit that sounds really smooth and transitions between volume and volume boost. In true boutique pedal fashion, TC Electronic throws in a true bypass to sweeten the deal. In the under $50 retail range, this is one of the absolute best deals out there, as long as you're in the market for a signal booster.

Spark Mini Booster. Mini is size... NOT in boosting.

This little pedal ROCKS! I have used EQ pedals, light and transparent overdrives and volume pedals in the past to give me that lift when I am soloing or emphasizing a phrase. Always struggling to get that lift. Rotated off this pedal meets guitar volume.. that is parity... (EQ pedal is half way, with opportunity to decrease volume). This is a boost. At 9 o'clock it is a completely suitable soloing and phrasing volume. At 12 0'clock I was clambering to turn it back down a touch... and it still winds around to 5 o'clock. Don't let size fool you... 20db. No false claims. The best feature is the unlatched footswitch. Stomp it on for the spotlight moments, press and hold to grab a moment then as your foot leaves, so does the boost.

Great little booster

I love this little pedal. For the price, you really can't go wrong. It adds a nice little boost to your signal. I love the grungy tone of my Boss DS-1, but I hate how it sucks the volume out of my chain and generally sounds weak. I use the Spark Mini Booster to boost the volume on the Boss DS-1 and it works great. Just remember, a little boost goes a long way... I usually leave mine set to around 8/9 o'clock. Anything more than 12/1 o'clock and you'll start breaking up.

Powerful, transparent, perfect

The output on my sixties Ibanez pickups is quite weak, but the sound is very beautiful. I just wanted to give some more power (and some girt, if tweaked) to the signal, and this little booster sounds great, giving plenty of drive. I use it on 9 o'clock, but the overall sound gets wonderful when fully clockwise (I guess I'll put some other overdrive pedal on retirement, coz presence and bite is what I really want first, on a clean channel)

Grants an amazing volume boost with practically no tone colouring making it perfect for solos
