The talkboxes Bigg Robb make aren't very good on a visual level, I've heard some bad stories about people being disappointed when they recieved their talkbox from him. First, it's a cardboard box, wrapped in black electrical tape, the vinyl tube is attached but if you want to change the tube you have to go through a lot of that tape to get to the end and it smelled like it was in someone's attic for years... very smelly. The sound is to crisp and very high.
One guy even paid $350 for his robboxx and wanted to through it away after seeing it and hearing it. Another guy said he wasted his $220 on it and trashed it. So I don't know about purchasing his talkboxes if these people and others are complaining about it's sound and appearance.
So, my thumb is down on getting one.
