First off, I do not review many products. They have to be either bad, or really, really good. This one falls into the latter bucket.I've been playing the guitar now for about 25 years, off and on, but not seriously until recently. I picked up a bunch of gear earlier this year, and had a list of pedals and other stuff I was planning to work through, but lucked across the Spark series. I'd planned to get the Go, which technically does what I needed it to do right now, but decided to spring for the Spark 2 so I don't have to go get another one in a few months. Boy am I glad I did! Wow. I have only spent a couple days with the amp so far, but already I've thrown away my old list. I simply don't need any of it. The amp models and pedal options check off literally everything. I would highly recommend this for anyone at any level. If you're not looking to spend as much, the smaller models do all the same stuff. Get your foot in the door, ASAP!After a couple days, I was sick of staring at my phone for hours (the app keeps the screen on, at least on Android) and reconnecting the app every so often (I suppose if the app doesn't use the connection, the phone closes it to save power), so off to Google I went. Turns out there's an app (PC/Mac/Linux) that someone created (no affiliated with Positive Grid at all, from what I can tell) and web browser based option out there, which I found much easier to use. There are also pages with mappings from the names of the amp models and pedals in the app, so don't be afraid to dig around.All around, exactly what I wanted, before I even knew I wanted it. Also, everything I needed, with zero hassle. Plug it in, turn it on and jam. It takes a little time to get used to the app, but it's not exactly simple; finding a starting point is impossible to screw up though and you can go from there. Professional sound in a portable package that requires little to no experience to start using.EDIT: The SoundShed app technically supports the Spark 40 and Mini, but I have used it with the Spark 2 and it works to control the details of existing presets, change the amp/pedal models and switch to other amp-stored presets, but you can't switch to something that's not already saved and can't use the ToneCloud setups. This is not a dealbreaker for me, since the phone app works well for that, and with the Windows Phone Link you can see it on a PC. I just wanted to clarify since I started poking around and noticed. The SoundShed desktop app doesn't work well with the 2, but the web version does.

I have sold all my guitar gear to get the and I don't regret it one bit. The amp is tiny but mighty. The tone cloud has nearly every artist you can think of and the effects of which there are thousands will have what you need to recreate that signature sound. I created my own backing track for a full concert and I have saved every sound I need into the 8 slots. I purchased the control x pedal to go with it. The master volume on the amp controls the master volume of the amp inside the software. The guitar volume controls how loud the guitar is overallAnd the music controls the music volume. Having stereo out makes it easy to go into my pa system which is 1800 watts. Now I have everything in a tiny beautiful box that I can control from the app on my phone. It truly feels like I have arrived at a time in my life where now I can go out and gig and no longer bogged down by wires and power supplies. Just one power supply. A fully Charged control x pedal and one guitar lead is all I have. Downsizing but upsizing in effects. My guitar playing has improved dramatically having the sound be closer to the actual artist. I'm having the best time with it and I've only had it for a few days. I'm going to get the battery next month for it. If you get this you won't be disappointed. Plugging the headphones into it disabled the speakers but the sound through your headphones is phenomenal. The built in tuner is brilliant as it shows you when you're in tune but it also shows you the drift to sharp or flat. Sometimes the string will be in tune but ever so slightly sharp or flat once the volume of the string dies down. Much better than any tuner I've had before. The amp controls the app dials of the virtual controls but not the other way round so bare that in mind. If you move a control when you are playing it will alter the whole sound. So you need to set the sound as you want it to be and store it. Then when you select the patch you want its all set. If you have a sound set that has a lower volume stored it will play at the lower volume. This is excellent as sometimes you don't want to adjust the volume on the fly you can do that with your guitar volume but you might want to be arriving at a lower volume. With this amp you can do that. Truly outstanding bit of kit. Don't get the 40 version as it doesn't have the output to pa and sound quality not as good at 50. Highest recommendation I can give and even though it's classed as a practice amp I'm using it with a pa and using it live. It's perfectly capable once you have stored all your sounds in the amp. I would not use the Bluetooth live but only for downloading and modifying your sound before hand. The great part also to mention is that once your sound is stored you don't need to open the app to modify the effects as the amp dials affect the delay and reverb gain etc on the actual amp. If you are a serious guitar player like me get it. 5 million stars

Vraiment un super produit!!!

Una maravilla. Suenas como quieres al volumen que quieras, ojalá hubiera tenido esto hace 20 años.

I had doubt buying this. Was not sure the sound quality and loudness is any good. Specially being that small. Now I am amazed by how good it is!!! The selection of amps and pedals are just amazing. The presets and the community list of presets are fascinating. I so regret why I didn't know such great product exists and instead of investing on so many amps and pedals, just buy this.I highly recommend this to everyone. Not just a practice amp, but a great music companionship with all the great features in the app.
