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.
