“As someone who has a code50: I dont really like how the phone app works... I found myself never using it (the bluetooth connection being hard to establish is also a pain) and wishing i could just tweaking and making presets on the pc like you can with the mustang. Maybe marshall will make an app available in the future, i really wish it.”— PepAlmeida on Reddit
“I first had a marshall code 50 and liked it a little but then I got a boss Katana 50 and very quickly sold the code 50. The code was every bit a digital modeling amp but the katana sounds like a real amp”— zelda29a on Reddit
“I've had a Marshall Code 50 before and would 100% recommend the Katana over it. I never really thought the Code sounded good, and feature wise it felt a little lackluster.”— Cornelius____ on Reddit
“I upgraded from a Marshall Code 50 and the difference in feel is insane!”— Roaryn22 on Reddit
“Marshall CODE 50, most settings had either too much or too little gain and everything was boomy and shitty Bluetooth speaker levels of bass.”— SmytheOrdo on Reddit

“i have a code50 and it doesnt sound bad but it has a bit too much low end and some of the effects sounds kind of fake, also the sound is a bit compressed to me.”— weggejorist on Reddit
