Yeah this is wath I spoke about ^^ (in your link) I bought the toy but on the box they don't speak about radio mode .. after finshed the game I'm looking on the net and found this : oafe . net/yo/tfg_wfcsw.php is this boom box mode who inspirated me =D to create voayger soudwave .. at the beginnig I would create a mixage table for a gi.joe DJ .. but I belived isn't a good idea =s ..

Very cool!
You have taken a figure I am not at all fond of, and made it into something awesome!
I really like the cybertronian boom box mode.
Hi, I have that figure, (it is pretty slick) and I have not seen the boom box mode. Can you post a pic?
Edit: Found one about 3 posts down:

In belgium they're some new transformers from the game "war for cybetron" and into them they'is a splendid soundwave figure , he can transform into robot mode car mode and a boom box , I'm inspired from it to custom this figure , I didn't use soundwave in fact but rockblast , cause of the legs and the chest , (more tip)
thank you very much to your comment , I apologyze for my english =s I come from belgium and I always speak french

Very cool mod, I never would have thought of that. I wish they'd throw us G1 fans a bone and just make every soundwave a triple changer with a boombox form.
