I wish it had been available when I was starting out. The problems you will read about on the internet all appear to have been solved - slow delivery, strange humming, all gone.Despite its small size it has the sound of a much larger amp. I've not played for real all the amps it models but they sound good to me. Some of the reverbs sound a bit samey, but other than that I couldn't fault it. The practice modes are very usable, playing along to backing tracks on YouTube is fun, composing with your built in drummers, a challenge.If you've seen the videos and been unsure, get yourself one. You won't be disappointed. ### ⭐⭐⭐⭐⭐ Excellent amp, plenty of features *by on Reviewed in the United Kingdom 8 October 2021* This is probably one of the best bits of kit I have bought. Easy to use and setup; even updating the firmware is simple to do and is done within a few seconds. The app is easy to use, but I don't like how Android devices require location to be on to "sync" with devices like this (it's a google thing I believe) but otherwise no complaints. You can even preview tones on your amp before you download the setup.I saw a bunch of reviewers saying they got a buzzing sound when using it unless they bought a new cable, but mine appears to be working perfectly fine.One thing to be aware of is when you use this as a bluetooth speaker (great feature) it is insanely loud and the volume dials mean nothing as these relate to the guitar channel. The volume is controlled by the volume of your connected device (phone, tablet, laptop etc) so is a huge shock if your not expecting it.Would highly recommend as a good practise amp and even for small gigs (like pubs/bars) as it can go pretty loud being 40w. ### ⭐⭐⭐⭐⭐ Absolutely brilliant amp! *by on Reviewed in the United Kingdom 14 March 2026* The key and most important word is PRACTICE. I’m bored of reading reviews saying it won’t do this and it won’t do that! Some think they are reviewing a Marshall 100 watt head on top of two 4x12 cabs. It’s a practice amp with software that’s free! Thousands upon thousands of tones, a cloud to share and download other people’s tones. With the head phones on it’s unbelievable! I’ve even purchased one for a good friend of mine who’s less fortunate than me. Great value, great sound and easily carried to jam sessions. Remember it’s a freaking practice amp!!!! ## Frequently Bought Together - Positive Grid Spark 40-Watt Combo Practice Guitar Amplifier Electric Bass and Acoustic Guitar Amp with Spark Mobile App - Fender Professional Series Instrument Cable, Guitar Cable 10 ft, Guitar Accessories, Stage Ready with Anti-Kinking Design, Black - Fender Premium Picks Sampler - 12 Pack Includes Thin, Medium & Heavy Gauges (Austin Bazaar Exclusive) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/241798141-positive-grid-spark-40w-smart-guitar-practice-amp-and-bluetooth](https://www.desertcart.hk/products/241798141-positive-grid-spark-40w-smart-guitar-practice-amp-and-bluetooth) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-14*
