  • Try this again with the Spark 2. You'll find your 7 reasons have been reduced except the lights inside the box.

  • All good points, except the Spark sounds better than the THR. I have the original THR (C) and the Spark Mini. To my ears, even the Spark Go sounds better than the THR.

  • Most importantly, the Yamaha sounds way better without any tweaking. I have both, I know. Probably going to give the Spark to my niece.

  • I have a thr10 i got a few years back, amazing for a casual player, fun and takes pedals well, and sounds great.

  • I currently have nine amplifiers. I’ve had several dozen amplifiers over the decades, my favorite all-time were the fender super reverbs I had except for the fact that they are so tall, it’s easy to bang them on things when you’re carrying them up and down steps, especially. I currently have 2 PV classics/Tweed, a classic 30 and a classic 50 with 4/10 inch speakers. I also have a tweed Peavey Deltablues with the 15 inch speaker. Those are all tube amps with switchable channels, post, and pre-gain control, spring reverb, and the classic 50 actually has a built-in cooling fan. It’s exactly the same size as a fender super reverb because I have a fender super reverb cover on it. I also have a fender cyber twin, and a Hughes/Ketner Zen combo amp. The fender and the HKR Amstead have many many standard defects built in, the HK I have was built in Germany. Both of those apps have 2/12 inch speakers, the fender has many other circuits copying other fender amplifiers all in one amp. They claim it’s not a modeling amp, they claim that when you dial up something like a pro reverb or a Princeton or a champ, the amplifier actually since the signal through the exact circuitry of that amplifier you dialed up. My favorite two are the twin reverb and the super reverb. My HK is a modeling, it has memory where you can program it to bring up 100 or so recess you have dialed in, plus it has the circuitry, mimicking particular amplifiers, like fenders, Marshalls, vox, and others
    my wife was at a garage sale and bought me a fender front man amplifier with a claimed 38 W, single 8 inch speaker, absolutely brand new condition, it’s not even dusty. No built in effects. But I plugged in a couple of my preamp pedals , and it is shocking how well that amplifier takes to pedals. It sounds so crisp, and it has full tone because it’s a closed back cabinet. Does it sound better than any of my tube amplifiers or my fender cyber twin or my HK, I don’t know, it’s pretty close to tell you the truth. But my point is, this little amp that I would not have given a second look to at that garage sale. My wife was at that bought me this amplifier, but it kind of open my eyes to small amplifiers. I’ve been going online and checking out different reviews on YouTube. The Roland, mini cube gets the highest raving reviews from the owners of those amplifiers. One very, very good guitar player said that it is the perfect amplifier. Other obvious experienced guitar players, have said, you do not need another amplifier. If you have this Roland mini cube. I have always been able to tell blindfolded the sounddifference between a tube and a solid state amplifier.
    my very first modeling amplifier with built-in effects was the crate DX212. I went to a local music store and I wasn’t even looking to buy an amplifier, but I plugged into that thing back in the year 2000 I think it was. And I walked out of that store with that amplifier, I went home and sold both of my fender super reverbs that I used on gigs for years. But, I soon found out, that that amplifier although it had 212 inch speakers, it just could not cut it in a live setting with a drummer and a bass player. It was pretty pathetic compared to my super reverbs, especially. So I’m a little leery of solid state amps ever since. I’ve gone back to tube amps with my collection of Peavey amplifiers. That’s Peavey classic 30 with the single 12, all tube, switchable channels, pre-and post gain control, is enough to keep up with a drummer and a bass player on a live gig. If that’s not enough if it’s a big place, my classic 50 with 410 inch speakers will move a lot more air. All three of my PV tube lamps ironically all have the same number of tubes and they are the same tubes in all three amplifiers, they are also the same tubes that they use in Marshalls, I think that’s EL 84 &12AX7…
    I spent a few days searching the Internet, mainly YouTube for reviews on small amps that I can crank up to get some harmonic sound from the cabinets without blowing the windows out. But every time I find one that I think I’ll go by, that little man in my head convinces me that there’s no way it’s gonna be better than the amps that I already have . And if I want a nice sounding small amp, I already have that fender front man with 38 W and an 8 inch speaker that sounds fantastic with my zoom preamp pedal with all those effects built into it that I can use up to five effects simultaneously using that pedal, and my wonderful Yamaha DG stomp pedal with all those cabinet, simulations and amp simulations and all those tweak effects built in, including a tuner, I don’t even need an amplifier with that Yamaha DG stomp, just a head set if I want silent practice

  • If you know how to eq the spark 40w then it’s better then that thing by far I actually have a friend that uses that thing for church so I’ve tried it

  • I have just bought a Positive Grid Spark 2 and I am very happy with it. I just want to play on tracks, learn and develop tech skills on guitar.
    I am sure this amp is fantastic though.

  • Is the THR one of those modelers where you can't have more that one modulation effect at a time? Kinda how the Line 6 modelers used to be

  • I am a fan of YAMAHA MY favorite guitars are YAMAHA..Nyy pacificas and Sg and acoustic. They make great everything. .I've tried to lije the thr amps but just doesn't sound right to me Ive always lijed tube warmth and real sound but recently i changed to play a line 6 pod go thru headrush fr soeakers out of the pa and I understand Line 6 is YAMAHA . But for a small desktop or practice amp I wanted to like the THR line of amps ..but it sounds wrong to me. Maybe I'm not doing it justice because I BELIEVE YAMAHA MAKE GREAT products .PIANOS,Drums,Guitars ,Boat motors ,motorcycles, sound systems.whatever they do ,they do it very good ..many amps with software ,the factory patches suck.so maybe I need to tweak it with their software..I dont own one .but maybe if I find one used I can afford it. BTW I think the spark sounds waaay too fake .

  • These amps should have a touch screen so that you never need an app to access all the features

  • So many more tonal options with the Spark and now the Spark 2. You still have to utilize software for both and I would rather have the convenience of using my phone. Positive Grid blows Yamaha out of the water on this one. So many more modeling options on the Spark.
