I bought my new JTV-69 (sunburst, Korean) three days ago. I made initial regulations and updated the firmware to the latest version.box. Btw. Do I have to use external power for Variax everytime I want to use Workbench? I recharged the battery, connected the guitar to Variax-USB unit but it wasn't recognized (the red flashing light) till I powered it from my XPS A/B.

Models switch/knob. From the first touch I had to use much more force to switch emulations on or off than I expected. Light touching the knob didn't worked. After three days I can see that it's worse now. I need to press three or four times to switch from magnetic to emulated models. Sometimes, after pressing the knob/switch it stays in the "pressed" postion, then slowly moves up. How about your guitars?

Tremolo. I noticed very ugly noised when using it with modelled guitars. When playing with magnetic pickups it's OK. However, when I swittch to piezo I can hear every touch of the tremolo as a low rumble, when use it for a typical stratocaster tremolo effect (small moves up and down, no dive bombs etc.) it produces a lot of rumbles. It looks like piezo without high pass filter... Is it a problem of piezo, springs or the JTV-69 construction?

Kindest regards,

Jacek
