I recently bought a marshall code 50 and I am really dissapointed. Any tips for making it sound better? I have spend ages on it trying to get a good high gain tone but it just sounds 'boxy'. Any help would be greatly appreciated.
The one thing I would say is that the Code amps are quite directional, and being closed back can have a lot of bass. I would consider lifing the amp off the ground and if possible tilting it back a bit (stick it on a stool or put something under the front of it).
One mans high gain is another mans light crunch, so what sort of artists do you want to actually sound like, is there no downloadable patches from this site that have artists with the sounds you want?
There are a lot of possible options and combinations with these amps, so its best to simplify things when looking for a sound, you could try switching off everything, in particular the cab section and power amp section and play with the different pre-amps and distortion pedals to see if you can get a sound you like. you can then try adding in power amps, cabs and effect to see if you can improve the sound. You dont need power amps or cabs, so if it sounds better without them just keep them switched off.
Lastly, there are lots of youtube videos of the code, see if you can find one with a sound you like, the chances are their sound patches will be available either in the video or on this site.
I hope this helps.
