I wrote in a question you can please excuse me as now that I have the amp in hand, I am very happy. This is excellent.
I would consider how to add a high frequency speaker so music streaming is a bit brighter, but I notice the sound via USB is pretty good and one up on the Mustang series which did not stream music out the USB port. Thank You. I kept my G-Dec 3 Thirty around for that reason (plus tweeter and line outs - I might add). As I get used to this I might find the headphone out sufficient but wish you had added Lineout so the speaker stayed engaged but could take the lineout to other amps or recordering devices.
Can you tell us which interal speaker is used, ohm rating and the frequency response?
I do not want to open it up to figure it out since I plan on maintaing my warranty, at least for the next year.. :)
PS who signed off on this design, give them a raise :). But if you had a version with the features I mentioned, I would gladly have paid the additional cost and only been fully satisfied. Like I am at 96.75% now. You can quote me.
The speaker is one we had designed for CODE for us, impedance is 4 Ohms. All other information can be found on the downloadable manual at https://marshallamps.com/products/amplifiers/code/
if you plug a mini-jack halfway into the headphone output there will be a signal available at the cable being plugged in, while the speaker is still working... i discovered this by accident
be aware that the signal from the headphone output is not that hot though, unless you set the master pretty high, which will result in a pretty loud code... it's a true marshall for that matter :)
