When the TM F-22 came out, I saved $200 for one. When I ordered, it only lasted ONE WEEK before it went kaput. Pots were not working at all. They sent me new pots, with no instructions at all on how to install them.
I found no instructions on the net back then (1996) on how to install the pots, I opened my stick, tried very hard to install the pots, but ended up breaking my stick.
$200 down the drain, I couldnt send the stick back for a new one, and no one could help me repair them. After many months of trying, the stick ended up in the trashcan.
When I was 16, I had to work VERY HARD for $200.
