    Just could not take it anymore and broke out the tools and performed surgery to shoehorn this GB 128 in there, and after some cuttin and hackin it fits. It sounds like it was supposed to be there all along, much better.

    Sure wish they would have done a 12. I went with heads instead because of it. Did you open up the hole?

    Yep should have come with a 12, I regretted not getting the head and considered building a head cabinet. I opened up the hole with a router / counter top trimmer. I took the baffle out and did it as careful as I could. I did not have to take the grill cloth off, I just shimmed it away from where I was cutting and vacuumed the saw dust out.

    What's the baffle made of? MDF?

    Old thread I know and my first post, but I had to reply with my results for others who are thinking about doing this, like I was.
    I researched a lot and finally put a G12M Greenback in it. I opened up the hole with a jigsaw so I had to remove the grille cloth and piping (lots of staples), but it wasn’t too bad to put back together with a squeeze-type stapler…looks like I never even did the mod.
    The amp now sounds so much better. I struggled with a G10 Creamback for so long. Now it sounds like it should, and I’m thrilled!

    G12M + Marshall = Good choice.
