Awesome amp
Kingtt 17.11.2019
Very versatile amp, can be used in in wattage ranging from 40w down to 1w or no watts for silent recording and comes with a bunch of basic effects. Comes in a bag that makes it super easy for transportation, but what I really love about this amp is that it is a hybrid and what I mean by that is that it is an analog tube amp with digital functions that lets you truly control every single effect of the GrandMeister Deluxe 40 precisely on the iPad app and with this amp, there is only one con which is that you would want to get a midi controller if you want to turn off the effects that it comes with after use, however you can still very easily change the settings on the amp but you can't turn it off. And about the app, you can use your own presets on any other GrandMeister deluxe amp without having to take your amp to every gig which is an awesome feature, that being said, this is my go to amp mainly because of it's features, with a variety of tones that are hear melting, it's half the weight and size of a regular 100watt head, it is plenty loud like you could actually go deaf if you crank the amp, and even when power soaked to 1watt, this amp still delivers enough punch and volume and I never crank it at home.
Of all the amps out there, I think this is one amp that you cannot just have enough of, if you love buying heads, this one is a bad news because once you get this one, there is no going back, it's just this one and that's all. So yea there you have it, I don't want to write a whole biography on this amp, I don't see how there can be anything better than this, it's the perfect marriage between analog and digital processing, beautiful aesthetics, all the useful functions and effects multiple tones, stepping down the wattage thereby eliminating the need for an attenuator, and if you get this amp with the midi footswitch, you got a tuner and a slot for an expression pedal, it has a built in noise gate. I highly recommend this amp to any musician that wants to get the Grandmeister deluxe 40.

Amazing versatility and the midi is superb.
A whole tones for home and lives.
Buy it if you want something to <<do it all>>
Every channel is good.
It is the best amp for versatility and for saving money
The tones are fantastic, and it can get a lot of pedals with good behavior.
The effects, the noise gate and the boost is good too.
If you buy it and change the tubes, you will see a big difference.
The weight of this is excellent.
Just buy it
It is the best versatile amp for this money.
My opinion is that if you want a versatile amp, and you want something better, you will definitely need a mesa boogie amp or something like that plus the effects. So we are speaking for 20-25 kilos for fun.
I recommend this for sure.
I have a lot of amps. Fender super reverb, Kitty Hawk Quattro preamp, and others.
If I have to go somewhere, I am taking this with me.
Believe me it is okay for everything except you are recording like Lukather.
If you are this level player buy 200000 euros equipment plus audio engineer and some trucks and people who will bring them everywhere for you.


Very gos amp
mm00024 07.01.2018
1) Many features as you read them in the manual
2) Nice lighting
3) For home use you wont need more than 5 watt power and its still a lot
4) Small size
5) The transparent material in front is not glass its plastic so you dont need to worry about breaking it
1) It get too hot after long use
2) Master Volume is not controllable via expression pedals and not smartly controllable when you change channels so as to remember different setting for each chanell. If you want to control master volume then you need to put a volume pedal in the effects loop
3) China made tubes
4) Redbox out if you want to place headphones directly for night use you cant, you ll need headphone amplifier or PA
5) Boost should have a boost knob so you can choose how much to boost cause you need sometimes more boost than it offers


A first choice for a 1000? budget
Anonymous 30.01.2017
Very good all tube amp with an affordable price.
Great tone, with 4 channels.
It has also an fx processor incorporated with chorus, flanger, phaser e tremolo. Delays and reverb too.Those fx won't be my first choice eventually, but their quality doesn't compromise at all the overall quality of the product.
I can use it at home, studio, rehearsals and live with all the features.
40W max power, for me is more than enough. You can also work with 20, 5, 1 and 0W for recording with all the tone.
