I have a Scumback H55 (weber build) that I sent in for repair because it was crackling at medium to high volume. Now that it's back, the cleans sound tremedous even tremendously loud. But ANY overdrive I run through the cab/speaker sounds terrible. Ripping paper, super squashed and tight, just bad. Think of the smallest sounding, tightest G12H30 you can imagine and that's it. Does this need to be broken in because it was rebuilt, or is something else going on? I already have a lot in this speaker, don't want to invest more cash -- I will just move on. But I would think if the speaker was still messed up ANY tones would sound bad. The cleans are killer?
