Details on the Ultra Phonix Mod (UP)

Post by pompeiisneaks »

Here are two great short threads on the Ultra Phonix mod that Howard Alexander Dumble used to perform on amps.

Here's the first, a great discussion about Ultra Phonix with details on what it means, as well as a ton of clips of the amps being played.

and a newer one with detailed photos at that start and details of hte mod summarized in comment near end of the first page.

This is to be stickied so the UP is easily 'findable' in one location. (the other two had been stickied, for good reason, but could cause someone to read one and not the other.
