You're welcome! Happy if I've helped.
Rambo has no feedback, not like HoD4 which has rumble. Rambo uzis have no rumble motor inside.
Good to know about Rambo...
Update on sound issue, the headphone amp had very minimal effect, nothing that was practically useful, volume went up a bit but was distorted turning it up all the way and was still too low to hear while playing.
Going to try something else, getting piggyback rca splitters witha 3.5 mm audio jack in it to see if I can run the sounds through the amp boards in the cab, using the cab speakers and bypassing the computer speakers altogether. Hope this does the job....will have to wait till fri to try,
