    • My new go-to amp
I was looking for a battery powered frfr to use with effects pedals for odd gig locations and found this. It's been working out great so far for my purpose. Make sure to go to the mixer settings in the app and set channels 3/4 to stereo if you're plugging in a stereo source to the L/R inputs unless you want them to sound mono. It would be nice to have a hardware switch to toggle that. I may get a second one soon for backup or if i need better separation and want to get louder, but this thing gets fairly loud! I haven't tested the limits yet though. Added bonus is that we've cut a lot of equipment out to connect to this single unit. We've used all inputs and even added splitters to the back channels while using bluetooth. It still sounded great. I still prefer my effects pedals for more control, but you can get some really good tones from the ch1 amp models and effects, but it is app dependent and not as customizable (fixed signal chains and no deep parameter adjustments). Once you get all the banks filled to taste, you won't have to worry about going on the app as much. It's also fun to practice on and looks handsome. Less wires works for me. I hope they continue this line of amps. ... show more

    • Great amp/PA
This amp is a really good product, that could be perfect with a few changes. I'm using it for a single/duo playing to backing tracks and it works great for that. I also use it in a band as my guitar/keyboard amp. You can read the description from Spark, so I'm just reviewing real world use. The pros: *Very clear sound with good bottom end for such a small speaker. It's cleaner than most PA systems. *Loud enough to fill a small to medium space. I'm talking a coffee house or small pub. It projects well to the back of the room. *Small and lightweight which makes for easy transport and setup. *Four channels are enough for most singles, duos, or small acoustic type acts, which is what this is really made for. *Bluetooth connects easily and seems to keep the connection without any problems. *I like that you can put it on a stand or tilt it up from the floor. *The feedback rejection is fantastic. I can literally get 1 foot away from this thing with my headset mic on and it won't feed back. *8 built in presets are plenty, should be enough for most people. I bought the Xsonic Airstep switching pedal to use with it, and it works great. Cons: *It could use an Aux In jack. The only way to get music to it from tracks is through Bluetooth or you have to burn one of your input channels for it. *As others have said, I wish you could change the order of effects in the app. I'd like to have EQ, reverb, and delay all on the vocal channel, but you have a choice of EQ or delay, not both. Maybe a future firmware update? I still gave 5 stars, even though I'd like to change a couple of things. Positive Grid did a fantastic job with this amp, as they have with all of their products. I also own the Spark Go and love it. ... show more

    • All the hype is TRUE!
It’s totally all it’s hyped to be. For a small gigging musician or I’m even if you’re just someone who likes to jam, this thing is amazing. I can have a microphone and guitar and bass going at the same time and it sounds amazing. It’s like having a whole setup in a fairly small amp. The spark app has so Many backing tracks available it’s crazy. The app also has a ton of effects premade so you don’t have to mess with it too much if you just find a setting you like. I’m still figuring it all out but man it’s cool. It’s loud, it’s fairly light. The battery doesn’t come with it, I did buy it also. I haven’t used it on battery power much, but we had a planned service power outage for about 4 hours and it played loud and normal the whole time while using it as a PA Bluetooth speaker from my phone. I used it unplugged for about an hour playing guitar and singing into a mic while running it through GarageBand. It worked without issue. For what it is and what you get it’s a great value. I’d not owned a Positive Grid product before but had considered many times. I’ve seen all the YouTube channels review all of the various Spark products, including this Spark Live. It definitely lives up to all the hype. It’s a great machine. ... show more

    • Ch1 hiss
Not sure if Positive Grid ships directly, which is a problem with Amazon. Received a clearly previously opened box but ordered new. Horrible hiss on Ch1, but none on Ch2. Didn't test mic channel. My guess, someone returned the item after hearing Ch1. Also nonsense, I bought as part of a bundle with battery, but couldn't get them to replace only amp at bundle price, so have to return battery and amp so that I can rebuy bundle at same price. Company has to loose a ton of money shipping used items and forcing returns on items that I wouldn't have to return if they'd just honor bundle price on replacement. I have a Spark40 and love it, but so far upgrading has been a waste of time. ... show more

    • Awesome amp
Wow! What can I say. This is a nice amp. I cranked it up. it’s loud. The feature that lets you turn a knob to get different sounds effects from clean to distorted is nice. You can stand it horizontally or vertically and, it had a rod in the back that lets you tilt it up. The app is a plus. There are a lot of features. Check out the website. I highly recommend. ... show more

    • Versatile but keep your expectations realistic
Doesn’t quite cut through the mix as well as they’d like you to believe. Still, it’s a very flexible amp. I can load four preset tones for an electric guitar one ch1 and another four for bass on ch2, throw a couple pedals in the mix and I’ve got a great setup for tracking demos. Sometimes I’ll run a drum machine through 3 or 4 for practice or songwriting sessions. But this amp was never going to be the “all in one PA for a whole band” that Positive Grid want you to believe it can be. If you keep your expectations realistic, it’s a great modeling amp for recording, practicing and small gigs. I lose connection with the companion app a lot, and all the added features like virtual drummers and chord transcription are clunky and useless. This is why it’s best to choose some core tones and assign them to the hardware, and use outboard pedals for further coloring and gain staging. PG should stop churning out new products every week and focus on their app stability, UI and customer service. Updates are a dicey proposition -my first LIVE got bricked when trying to update it. Took almost three weeks before I convinced a PG rep that I had tried every remedy suggested, and they finally emailed a shipping label and sent a replacement. ... show more

    • Spark live is very impressive
The spark live is a very surprising amplifier. I tried one out at a local guitar center, then purchased via Amazon. I have been so impressed with this and impressed with where positive grid has come. I bought the original spark 40 when it was in Kickstarter and was initially impressed. I quickly found the guitar tones very muddy and difficulty dialing anything that suited me long term; I stopped using it mostly. I then got the spark go and it reenergized me in the spark amps. The spark live is not exception. It's built so well, and sounds absolutely amazing. It is extremely loud and easily keeps up with a drummer. I use mine exclusively for guitar alon input 1, however I love the options to use the spark live any way you want. I also love the midi features. I have used midi controller to provide a master volume boost during solos. I would recommend this product for sure and would buy it again. I also blhsve the spark battery which is surprisingly impressive for how much play time you can get from a single charge. ... show more

    • Good product, with some flaws
It is a very good amp. I used for rehearsals and gigs in very small venues. The guitar sounds and effects are great. The sound quality is top notch for lower volume levels. Additionally, is the best speaker I have used for Karaoke. A lot of fun, because the audio reproduction via Bluetooth and the voice is cristal clear when used with a good mic. But be aware, it is not free of flaws: - Not as powerul as I thought - 4 Channels, but each one has a specific function, so you can not put 2 mics, for example, or two guitars. - Not great for bass, maybe for the size of the speakers. I preffer my 40W Fender Rumble combo even for rehearsals in my small room. For bass, it lacks of clarity, deepness and projection of the sound. - Oddly, the app has a fixed order for the effects (you can not edit the order, only on/off each effect and tweak some controls). I really have the hope Positive Grid fix this in the next firmware/app update, because it can be a deal breaker for some intermediate or advanced guitar players. ... show more
