Scott,
The only two production modules not listed on the website are the TV and EG5. The TV stands for Twin/Vox and Bruce himself described it on this forum as such:
"The TV is a Twin with Vox tone controls so it has the big giant hole in the midrange. Classic Vox voicing. Both the A and B channels have the same gain."
The EG5 is a silimar to the MHG module. Its a hi-fi high-gain module with a strong upper mid voicing. It is similar to a Soldano SLO-100 but has more low end and sounds more balanced. In prototyping it was called "JXH", but its production name is EG5 as it is a logical modern extension from EG3/4.
