alright. got my turbo duo back today that i sent to turbokon. origionally it came back but it seems that the post office beat the box it was in to hell and knocked something loose (not the first time this has happened to me) so my region switch was not working. talked to turbokon about it and he told me to send it back and he would fix it. got it back today so heres my review
i origionally sent him a tg express for a sound fix and my US turbo duo for a region mod and an amp upgrade (even though my express wasn't having any major sound issues at the time.)
got my express back and it sounds great so i'm very happy with that.
as for the turbo not initally working with the region switch i fault the PO for this and turbokon was very quick in repairing it and sending it back. so now onto the duo
i was a little worried at first because the sound kinda crackeled and went in and out for a second when i loaded up bonk but after playing it for many hours on and off since its running fine. i would even say it may sound a little better then it did before i sent it out. the switch works flawlessly now and looks pretty good. nice clean job on the mod. communication throughout the process was very good and always friendly. he was also pretty quick about getting everthing done and sent out as well.
here it is playing a PCE game
heres the region switch
i was pretty pleased with the job overall. hope this helps in clearing up things a bit for you here.
