    I am new here and have owned KTN 50 for a little over a year. I am very pleased with the amp. Just upgraded it to version 2. I am not a professional player so the 50 is plenty big enough for me, the wife thinks it is too big for the house. I have just ordered a new speaker for it from Guitar Center and it should be here tomorrow. The speaker I chose was the Cannabis Rex from Eminence.

    Ok, the cannabis rex speaker is installed in the KTN 50 and played for a coupe of days. Without a doubt their is a big difference in sound. I had watched a few youtube videos of others who had made the swap and thought from what I was hearing on the video's it would be worth the effort and it was no joke, man this little amp is wicked even on the low power setting it has a lot more punch than the oem setup speaker. The video's I seen showed people installing it in the same orientation as the original and doing some cutting of the wood shield that is attached to the bottom of the amp head and the wires going to the speaker at a 90 degree orientation like the original speaker. You can turn the speaker to the next set of mounting holes where the wires are going in near the bottom of the head, still easy to plug in when assembled, and all you have to do is cut a notch in the wood shield. Bottom line, the speaker change was WELL WORTH IT.

    Sounds cool.


    I don’t suppose by any chance you did a recording or video before and after?

    Sorry, I did not make a before recording. At the present I don't have anyway , other than cell phone which is not good, to do a recording after the install. I can post picture of the completed install. I am going over to a friends house to let him check it out and then I can get him to record it. He has his the microphones and equipment to do this with, LOL and the main thing is he is far better player than I am, you guys would be throwing rocks at me and my playing.

    There are a couple Katana vs Canabils Rex comparison vids on youtube.

    This is one of them. Tones @1:00


    I need another small 1x12 cab so I'll probably steal the Kat 100 speaker for that build. Think I'll put a WGS ET90 in Kat box.

    johnnymg, that is the video that sealed the deal on me going with the c rex. I had looked at other speakers but not willing to go for the C. Gold that cost almost double what I gave for the amp I decided to go with the c rex. The oem speaker sounded good to me but the c rex sounds better. I am going to make a cabinet and use the oem speaker in it. I don't have any pedals so the KTN 50 has saved me some money by all the built in features that I am still playing with. I would like to have a schematic of the circuit of this unit, would like to try my hand at setting up a Nextion 3.5 display with sd card to have more than just 2 channels and 2 banks of settings.

    My WAG on cracking into a Katana (and adding a display) would be through the USB interface. Would be quite a task even if you had the schematics.

    I did embedded processing and know a bit about this stuff but I'm retired now and the thought of going back to that woodshed gives me the willies. :p
    Good luck to you for thinking/attempting such efforts and shame on Boss/Roland for omitting this feature. :thumbd:

    That was my first WAG, go through the usb but I was more interested in tx/rx lines from the Nextion display to the processor in the KTN but I would not start that without having the information on what processor and the schematic of the amp and then I am sure the interface between the two could be a problem. I have been doing some programming of the Nextion and graphic interface on ham radio projects that are very involved with touch screen features and I guess I had a brain fart that made me think about trying this on the KTN. Yes, this is a woodshed project I should avoid.. LOL, and this is probably something the guys here don't want the site cluttered up with my WA idea..

    It's an amp that just begs for an onboard interface. A tough nut to crack for a HW hack indeed.

    The other approach would be to crack the Boss SW so it could run on IOS/Android. Doing a Google search will reveal a bit of activity on that front.

    Condor/Gumtown have the Android (6.01 or better) editor out there already, it needs a USB OTG cable.

    Is it a solid app yet? I saw a few posts indicating it was very buggy.

    Finally got my hands on a shiny new Katana 50, and am loving some of the tones it can produce! I'm especially loving the 0.5w option - I have a Fender Super Champ X2, (which I love), but I just don't get the chance to crank it, barely going past 2 for volume...

    The Katana is impressing me with how easy it is to dial in some nice tones out of the box - the controls are nice and easy to figure out, and it's so cool to still have the dynamics etc at lower volumes. I haven't even really played around with the Tone Central options yet, but can see that there's an impressive amount of tweaking that can be done if required.

    Next will be trying some pedals in front of the amp, but haven't felt the need yet!
    :)

    I’ve had my 50 for a few months now and it is a great amp.

    I really like this amp. You can crank it up and blow the windows out or you can play it at bedroom levels and not disturb the neighbors. Having the 0.5, 25 or 50 watt selection along with the standby mode is very nice and well thought out. The effects are just as I expected and with the five different amp settings (Brown, Lead, Crunch, Clean and acoustic) you can expect a lot of different ways to set it up. It has 2 preset channels with a panel setting and if you get everything so out of whack you get lost...you can do a factory reset that puts everything back to the original settings. It even has a little short leg on the bottom you can unfold so you can angle the amp upward a little bit. Plug in an i-rig and your i-phone, start the GarageBand app and prepare to get your mind blown.
    I have very limited knowledge about amplifiers so take this next statement for what it’s worth...I really don’t have anything bad to say about this little amp.
    If you have been thinking about buying one of these, do yourself a favor and do it!
