Really easy to use instead of the amp.

Although I am what most would call a “techy”, this app is very cumbersome in programming and saving presets.

This is ridiculous. This app has been broken for over a year. I bought a CODE25 and used the app, and it was incredible over Bluetooth. But I updated firmware and it will not connect at all now. I've researched the problem because tons of people are having the same issue. Every time Marshall responds saying they're working on it but still there have been no updates. I even saw instances where Marshall representatives told them to return the amp to the store. I bought my amp with the intention of using this app and there's been nothing done about the problem. Horrible customer service. Show more

I would love to give this a better rating because the amp is awesome.. but the App has the worst Bluetooth connection issues ive ever dealt with.. works for my i phone 6 but only if its within 2 “ otherwise it loses connection... so I tried using my ipad and it wont connect to the amp in the app bluetooth connects.. but the amp isnt connecting in the scan for amp window... so your app is not compatible with your products... its driving me friggin crazy and i feel like ive been ripped off... anyway hope this issue gets resolved last update was in 2016. May just sell it and quit dealing with Marshall all together. Show more

Been using the app for a while. Recently stopped working with my downloaded songs from iTunes.

Needs landscape mode and multitasking feature to adjust while garageband loops are playing.

I have to delete and reinstall this app everyday. When I first connect to it, it’s totally fine. Then it varies... sometimes after not playing for a few hours, it’s still connected, but sometimes it’s completely forgets about my CODE. My Bluetooth says there’s no amp to connect to. When I check my settings, it says I am connected, but it doesn’t exist I guess. Solid app though. Show more

Just bought the code25. I had to do a software update to the amp via usb and computer. I then was able to pair with my iphone and Ipad. However, my iphone with the app still does not work. It will pair but app is frozen. My friends iphone and my ipad work great. It seems truly amazing what the app and amp can do. Also to pair hold down 2 buttons on the amp. It will start flashing to pair. I can even use the riffstation app while using Marshall app. Hope this helps. Show more

Still a little clunky to manage presets between gateway library on computer, app, and amp. REALLY NEED a way to copy the WHOLE phone bank to the amp bank. not just one by one. I don't want to manage amp and phone separately. If I shuffle presets on the gateway the sequence on the phone changes obviously, then the amp (and stomp switch) are different. And if I tweak on the amp, I want everything to go to phone/cloud. I want amp and phone to match in case my phone is dead or elsewhere. An auto-sync (that can be turned on/off) between amp and phone bank would be even better. Bluetooth doesn't always connect. iPad 2 does not even find the amp. Phone/Message sounds come on speaker while playing. Show more

So much easier than trying to fine tune through the amp itself. You can tweak the hell out of every setting. Turn things off and on easily, save and name your presets easily, sync with your amp easily. All via bluetooth. It took a coouple of reboots on my photo to get bluetooth working, but all is well now. I just recently starting using the playback feature to isolate a portion of a song in my iTunes library and slow it down to 50% speed. Awesome. One star because you don't actually own the amp that the app was specifically made for? Really? Show more
