Comments about Blackstar Id:Core Stereo 20 2X10w Super Wide Stereo Combo Guitar Amp:

Once You Understand It - It's Great!
I have never had so much fun playing through a solid state amp in my life!
It really has the authentic feel and rich tonality of playing through a tube amp. I'm impressed.
It reacts like a tube amp when using the volume knob on your guitar.

First: This is not a loud amp by ANY means!
20 watts in a solid state (transistorized) amp is not loud enough to play with even a quiet drummer.
This is the perfect bedroom, apartment or quiet/headphone amp.

Second: To get the most out of this amp you need to install the software to access all the features and settings.
The software is free and available on their website for Mac & Windows.
This can be tricky. To help avoid any problems do the following:
1. Make sure your firewall is not blocking the Blackstar Insider Application.
2. Make sure you have the latest Adobe Flash & Microsoft Silverlight installed BEFORE installing Blackstar Software
3. Make sure you have Microsoft NET Framework version 4.5 installed (or it will not work.)
4. Restart your computer and then install the Blackstar Insider Software.
5. Hook up USB cable, connect amp to computer, start Blackstar app and UPDATE THE FIRMWARE.
The App will not work properly unless you have the latest version firmware. This is done through the Blackstar app.
Make sure you do not turn off or interrupt the firmware update.

Once I got it all working & tweaked it turned out to be a keeper!

I have read some comments about placing the amp elevated or on a desk. I disagree!
Check it out for yourself. It sounds fuller and wider on my carpet in any room!

This amp has a great feel and notes ring out easily with full tone, attack and dynamics.
I doubt the 40 watt version will be much louder, a bit perhaps, but the speakers are 6.5", which is about 1.5" larger than the 5" speakers that are in the 20-watt amplifier and it may hold the bottom a little better.

Lightweight makes it easy to carry from room to room. (about 11.5 pounds)
Full fidelity speakers makes it sound like the stereo is about 9-feet wide!

NOTE: The audio input for MP3 player, etc., leaves a lot to be desired.
If you have a player with the ability to adjust the tone it will help immensely. Otherwise it will be thin and tinny sounding, but usable and better than nothing I guess. lol.

ALSO NOTE: The headphone output is for convenience only. It kinda sucks, very low in volume and there is no way to adjust the level other than on the player/device.

All in all I like it a lot. All too often small bedroom practice amps lack the feel, dynamics, reaction, and tonal fullness of a warm reactive tube amp, but this one makes playing fun and a low volume. Don't worry, it gets loud enough to feel it and get lost in the groove, and as with most amps when you drive it hard into distortion it gets a LOT louder, but makes the clean tones too soft when switching.

One anomaly is that even though the amp settings are programmable and will retain the settings, the main Volume is not. This is one reason why I only gave it four stars. If I cared about the audio input or headphone I might have only gave it three stars. Bottom line, if you want to use the audio in or headphone out, then you will be playing at a very low volume.

Nice Feature:
The amp uses a standard on/off (non-momentary) click footswitch for changing channels.
There are two footswitch modes:
1. Switch between two channels (selectable & programmable).
2. Scroll through the six presets (1-6 repeating)

I have been a professional full-time player for 30 years, own way too many high-end tube amps, and I highly recommend this amp for a small practice/warm-up/bedroom/living room/apartment type situation. It feels great and doesn't hinder your playing whatsoever.

The effects are terrific and the amp barely makes any noise, buzz or hum. (unless you go high gain of course!)
The factory presets are a good place to start, but the effects, although sound killer, are a little too heavy, so tweak away!

I play mostly Gibson humbuckers and it sounds terrific. I am sure that a Fender single coil would sound just a great with tone tweaking.

I don't know about their customer service since they became "big time", but years ago when I needed a problem resolved, Blackstar was on it immediately, but I have heard some snide remarks about their service lately, who knows, it could have been a fussy person...or not! lol.

It can get fairly loud on distortion, and IS loud enough clean that it could bother close neighbors or adjacent apartments, but the beauty is: When you turn it down it doesn't suck the tone away! It retains the tone, sounds, feels and plays just as great at any volume.

Amp uses a 10V / 3A DC adaptor.

    Comments about Blackstar Id:Core Stereo 20 2X10w Super Wide Stereo Combo Guitar Amp:

    My bro got me this amp as I was asking about something that was easy to fit into my room for recording and practice.

    Its just a straight up killer amp for the money.

    After plugging in I took a USB straight into the PC and it was on for recording!!!

    The Insider software is also great to keep getting updates from Blackstar themselves and

    the tone is super versatile from a really clean warm vintage tone throught to a stomping high gain sound. OD1 and OD2 include a built in noise gate which for a guy like me who ain't great on the guitar gives me a lot more control in my sound.

    The effects also record in this super wide stereo so you get a pretty huge sound on playback......and there are some seriously deep effects to check out!

    I'd recommend this product to anyone, new to the guitar or a pro who wants a really great sounding and versatile practice combo and way to make easy big sounding guitar recordings without micing up etc.

    I can't wait to try some of their bigger amps if this is what Blackstar can get out of a small box!!

    Nice tone, awful cable

    Comments about Blackstar Id:Core Stereo 20 2X10w Super Wide Stereo Combo Guitar Amp:

    Though compact, it sounds like a real amp, not like "toys" as other small amps do. I just hated the PSU (power supply unit/connection cable) that would fit OK for a notebook charger, but definitely not for a guitar amp. The thing is so weird that it is not even shown oh their website pictures.

        Comments about Blackstar Id:Core Stereo 20 2X10w Super Wide Stereo Combo Guitar Amp:

        Strictly put, this is a practice amp. It's plenty loud, and great if you live in an apartment. If you're looking for an amp to play with on stage, you're probably not going to want this. As a practice amp to play around with? This is the best I've ever used. How they get this kind of sound out of that small a package blows my mind. There's a ton of tone variety in the amp itself, but things get crazy when you download the free software. It unlocks even more tone options and you can save a boatload of sounds that you can unlock. You can basically control the amp entirely from your computer with just a USB cable. If you want to practice, this is as good as it gets.
