Blackstar ID core 20 V4 hard to beat
Got this for live streaming, but also as part of my recording setup, directlu to a DAW via usb, using phones output, not via the usb-c onboard the amp. Only succeeded in updating the firmware at the third attempt, and now utilise Architect software through a Hosa foot switch. The six sound settings cover pretty much what a lot of pedals offer: from bright to extreme overdrive; you can also change parameters in Modulation, Delay and Reverb. Saving and storing patches is an added bonus, while being able to use a TRRS 3.5 (shown as ‘External Headphones’’ in output) lets you play along with Logic, GarageBand, your DAW and audio files. Handy when songwriting.I’m truly impressed with just how versatile this amp is.

Excellent Product
Perfect for me. Replacment for a V2 10 which was good.but this outperforms it in spades. Would.recomend for all budding Marc Knophlers

Id core 20 v4
Amazing practice amp, presets are really good. Can't wait to use software to make some of my own patches. Only down side stereo version is not Bluetooth, but not a major issue

Before you buy
This is a great practice amp but only if you utilise the architect software to set your presets. I personally didn’t like the stock presets but setting my own has changed the entire sound. Cabrig lite simulation is a great feature too. For the price it’s definitely worth buying.

No Treble
Needs an EQ panel ie Bass/Middle /Treble it lacks this control so the Treble is not enough on this Amp.

Excellent sound quality and great range of features
Well first impressions of this are very good. It is quite a complicated beast and it is going to take some time to fully explore all the options because there are a lot of options to explore.It claims to be a serious upgrade to its predecessor but as this is my first Blackstar Amp I can’t really comment on that. What I can say is that it has a fantastic range of features that should satisfy most amateur musicians and probably a few semi pros. It is basically for home use but I could see it being usable in a small venue such as a pub setting.Sound quality is excellent with plenty of volume but can also be turned down enough for home practice at 1W. The V4 comes with a few number designations indicating the power rating. I am using the Core 20 which is a 20W amplifier with 5” speakers. There are also 10W and 40W models.There are six voices and as claimed the tonal range is impressive. You can even connect this to your computer using a USB connection to modify the sound parameters. It’s nice to see a USB C connection being used rather than the older versions that some Amps use.There is a stereo line in allowing you to play along to a backing track should you want to enjoy a spot of instrumental karaoke. It even allows you to live stream to social media sites. This comes with built in modulation, reverb and delay effects. Sound parameters can be adjusted using the free Architecture software. Patches can be saved and you can switch between patches using compatible pedals though these aren’t included.Physically this is a very nice bit of kit. It is not massive so can be left in a room without looking an eyesore. It is light enough to carry around without being so light that it bounces across the floor when in use. The handle is built into the back and is actually very comfy to use.The controls on top are clearly marked and easy to operate. This is a really nice piece of practice kit. It would be worth buying for a beginner as it will allow you to grow and still be suitable when you improve. The huge range of features are going to take a while to get my head around but having them means there is scope to experiment and try new things. The free software is good and not having to pay extra for it is a nice touch from Blackstar.This will satisfy my needs for a long time to come. There are always personal preferences with any equipment but I don’t really have any serious complaints about this. The price is good for something that is going to last many years. Blackstar have produced a great amplifier that should be on every buyers list for consideration.

Top di gamma
Preso perché da la possibilità di collegare il cellulare con la presa delle cuffie e di registrare video con audio direttamente dall' amplificatore senza bisogno di passare dal pc
User
Très bon ampli
Super ampli ! Je m en sers en complément d un ampli tout lampe , on allume on joue ! Très bon son en 20 w il faut monter le volume en 1 w . Les effets font leur boulot . Je rachèterai sans hésitation.

My first real amp and it feels impressive
This is my first amp so I can't go into actual technical details since I have no reference point. But I love the channel options and volume. I appreciate the low power mode since I play at home only and the headphone option is also cool.

Blackstar yine harika bir iş çıkarmış
Muhteşem bir ürün

Worth it for versatility
Great sound and versatile.Good out of the box sound once eq is set using laptop, by default bass is boosted. The basic six voices are great especially if you play all kind of music. However, if you primary play cleans go for fender champ. If you primary play distorted orange crush will be good for sound. But as an overall package blackstar is good, good voices, built in USB interface and great sound with minimal noise.
