I found this forum in my search for information about the Randall RG100ES. I appreciate all the information available, and have learned a lot. Finally, after fruitless interenet searching, I have decided to tentatively ask my first question.
As most RG100 users are aware the treble pull pot on this amp increases sustain, but results in noticeable volume drop. Reportedly, to combat customer complaints about this 'feature' Randall sold a product called a XP-3 Block Booster. This was to be connected between the signal out and speaker jack. These are fairly rare items to find for sale, and scouring the internet has only turned up external pictures of the unit. I cannot find any interior shots, schematics, layouts, or even a thorough explanation of what this box does. Any of the knowledgeable people here have this type of information, or guideance on how to clone one?
