Hi. First just to say that a am generally very happy with the CODE50 & it is definitely filling a gap to provide great practice tones with aux input from LickLibrary & my son's vdrum set to jam along! I have a coupe of items I wanted to put out there to the forum:

So the fizz - has anyone else noticed a very high end (treble) fizz or harsh crackle to the tone on most 'unsaturated' presets? It almost sounds like a digital clipping at the high end of the spectrum to my ear. It is definitely worse when using my 2015 Gibson Les Paul Less+ (which has the brass zero fret nut) like the amp is reacting to some of the pronounced higher frequencies on this guitar but it is also noticable with other guitars using a standard nut material.

The cabinet resonance I guess is due to the relatively light weight MDF that the cab is constructed of which appears to vibrate a little too readily has the master gets to about 1.5 / 10. I have dabbled a little with the resonance / presence settings under the speaker cab which has helped control it a little but I would be interested in any other ideas for reducing that boooom that can wash out the tone. I do have a 4 ohm Celestion G12T-75 from a long broken Marshall SS 50w combo which I am thinking of trying out - it is a physically heavier speaker than the CODE one pre-installed but I don't think structurely this will be a problem for the cabinet. I would appreciate any other ideas - anyone added noise suppression foam to the inside of the cab (as used in noisy PC towers) or anything else?

Cheers all.
