I'm having troubles with my VT Bass DI. For a long time now the footswitch has worked intermittently, usually taking a couple of presses or so to get the VT Bass to turn on (LED on). Now, it just seems to have given up on me. I tried the obvious, new battery, checked and rechecked bass input, etc., but nothing. It would make sense that whatever was working intermittently has now completely failed. So, I was curious if anyone has any recommendations on how to resurrect my VT Bass DI. It is several years old so I'm sure it's no longer under warranty. I have soldering skills so I probably would be able to replace the switch myself if that, indeed, is the problem. I'm not sure if it is directly soldered to a board or wired to one. Out of warranty repair by Tech21 is also a possibility.... If anyone has had this problem, or something similar, let me know what you did. Thanks.
