YAMAHA THR30II vs Positive Grid Spark! - Which one is the Best Practice Amp?

Let me know which amp you are most interested in and if you own one of these, what you like about it! Enjoy!

I have the smaller brother of the thr30 (thr10). Beautiful amp, and the tones you can get from that little box are insane. After the last firmware update we got a new tape delay fx and a more open cabinet set-up (like a mic further form the speaker) which makes the tones closer the sound of the first thr series.

I have the THR 10II and love it - it is so ridiculously easy to set up and get an amazingly good sound that I have played my guitar so much more than I ever did since I bought it. It just works and makes me want to play. Sure I could fire up my gigging amp and set up my pedalboard, and try to turn it down to a level that sounds good and doesn't annoy my family... or I could close the door to my office after the kids are asleep, pull up a jam track on youtube and 30 seconds later I am rocking along on the Yamaha, sounding great and not waking the neighbourhood. Best gear purchase ever.

I got a Yamaha THR, it’s such an amazing amp for home use. Tones are great, it sounds surprisingly big despite the size, and it’s beautiful to look at, not an eye sore on my living room table. The headphone jack, auxiliary in for my phone, and effects are sipper useful for practicing or playing at home or when it’s late at night. I also use it as a stand alone speaker sometimes lol.

Thank you for the in-depth comparison, Darrell.

the Positive Grid sound cloud is the real difference honestly. I've found so many amazing tones. The AI jam session stuff is fun too, and the ability to convert any YouTube video into chords is pretty neat, although I honestly don't use that function personally.

I have the THR30ll, because of the integrated wireless connection to the guitar ( with G10T) and also because of the tiny cute led lamps inside !

One use case I never hear people talk about that I LOVE my original THR10X for is for a minimal setup with a computer for recording. Over the summer I went up to a cottage with a few friends, and brought a guitar, midi keyboard and drumpad, and the THR (And an acoustic, because who doesn't want an acoustic at a cottage). Hooked everything up and boom, had everything I needed to get a good jam going, playing right out of the THR. I generally just use the DI from the THR and then use an archetype plugin, so I have a sound that I'd even be happy putting down on a track nevermind a simple jam with some buddies. When I'm not doing stuff like that it sits up on my desk beside my computer, so if I want to play loud I can just use that with whatever plugins I want, and don't need to waste the space/money on some speakers just to hear my guitar! For someone who loves to tinker around with tones and do some simple recording on a computer without investing a TON of money into an interface and studio monitors for some casual fun, it's truly a fantastic product. Before I discovered the archetype plugins, I also used the BIAS FX2 software with the THR, so you can technically get the best of both worlds with a simple laptop! (Maybe a good video idea)

WOW! That has to be one of the BEST true comparison reviews I've seen online or in print. Most of the time the reviewer never actually compares apples to apples. You went right to the heart of many important features. Your comparison on tone, build quality, sound, and overall appeal are spot on. I've been trying to decide between these two amps for mover a month now, and I think I finally have it all figured out. Price aside, if you can't find your own style and then fit it to the amp using this review then you aren't very focused. Using this information cleared up several issues for me, which mean that I could arrange my priorities for quality well before I even got the question of price. That just reinforced my overall choice. Thanks!!! I'm a new subscriber because of the video. HOpefully by th end of January 2022 I'll have the new unit in place and can post my own review. I'll let you konw how it goes.

Thank You Darrell, your expertise is always helpful, and I love watching you play guitar very much, you’re a mad man with that, I love that ♥️🤘🏾🙏🏾

Great comparison as always! The Yamaha is sort of a classic now but both sound really great. It's awesome how good you can sound nowadays for so little money

I have the Yamaha and I love it, I'm always amazed how close the tones are to the real thing! Great practice Amp!

I got the THR 10ii last summer after canceling my spark preorder. I waited 4 months for my spark but I couldn’t wait anymore. I love my THR! It might not have endless options like the spark but it is still awesome

I have the Yamaha's little brother, the THR10II, and I love it. Great sound, easy to use app and presets and very good sound when using other sources (phone via bt, for example).

I don't know why, but I always get a kick out of how Canadian you are, Darrell. Through that intro it always cracks me up. This coming from someone who lives in Alberta

Before Spark I used to play THR5, but then switched in favour of having more tone options/eq/channels. However, there are some things I've noticed 1) Noise gate. Seems like Spark has an aggressive noise gate, which can cut notes endings when you are doing a vibrato or bend or both. If you turn NG off, there will be a lot of hum (even with humbucker pickup). Replacement AC adapter which should solve grounding issues not helped at all. Depending on which amp preset you are, hum can be louder or quieter (on 5150 or similar high-gain presets it's quite loud and catches radio frequencies). I've settled with treshold and decay on 1 or less, which is quite compromising 2) Using as DI. Both Spark and THR have latency issues when it comes to plugging them via USB. Can be solved by dropping buffer size to the min value. Also Spark's DI sounds poor. The difference between what you hear from speakers and what you hear from monitors/headphones when plugged as DI is HUGE. Guys from support suggested this issue will be fixed by a firmware in future 3) Channel switching. Seems like Spark has some latency when you tap on CH buttons (both hardware and in app). This can be frustrating when you want to play a part of song via CH1 but then do a solo via CH3. And overall app+amp experience can be troubled with lags

THRii is pretty dope. The blue tooth cable thing is really what I like most beyond the actual sounds. As a house player, I end up using it 3x as much as my big ones

Got a THR10C a few years ago, and it made me practice even more from the start. Upgraded last year with a THRII30W for the wireless, the inside battery and more volume. Plug and play wherever you go, it will always sound great. I kept the THR10C though ;0)

I have a THR30II and have really enjoyed the experience. The battery lasts forever which makes it so easy to play all over the house and yard. I also really enjoy pulling up tunes on Spotify and playing along with headphones for an immersive "in the band" feel.

This is a perfect VS video, thank you Darrell for covering every aspect!
