Hi , i am trying to rollback the flash memory on a variax standard to v1.90 but it says i cannot do this as it needs lastest firmware, is this correct?. Thanks everyone.

Thanks psarkissian , that's brilliant info.

Hi just wondering did anyone, or is it possible to change sratchplate on a jtv 69 and convert it to a 69s and where could I buy the scratcplate. Thanks.

Phew, got it working ,just tried it again, remembering to have volume turned up and its working good.Thanks psarkissian.

Thanks ,will report back.

Yes psarkissian, ive have had this variax quite a long time and have reflashed it a few times, this one was from v 1.71 to latest

Hi psarkissian ,thankyou for the reply, I think I did click no on saving patches.Should I try update again and see what happens?. Is it possible for damage to occur if something disconnects during update.Thanks

Hi everyone , was updating my variax jtv 69 to latest firmware,but forgot to have volume turned up, and guitar went to sleep half way tru update and red light came on in usb interface and error message appeared, so I tried it again and this time it said update successful and showed latest firmware, however none of the modelling now works, did I damage the electronics?

I would guess the jtv 69 has latest firmware installed ,where in my opinion acoustics sound worse.You can reflash jtv back to version 1.71 and it will sound the same as your old 700. You can change it back again if you wish.

Ok got it sorted, bridge pickup was connected wrong way round on pcb board,swapped it around and all ok now, quality control missed that.

Hi I thought of changing pickups too on my jtv 69s because I thought 2nd position on toggle i.e bridge and middle sounded outa phase. I took a peek inside today and noticed pickup wires soldered back to little pcb board, it looked like it should have had black wires on one row terminals and white wires opposite side on board, but mine had bridge reversed, so maybe this is the problem. Hi gearhead when you installed new pickups can you remember what way wires were on board. Did you solder new pickups onto that board, would be tricky I guess. Thanks.

Ok got it sorted, gives option to roll back from file, I didn't have the file, when you go to download it with windows 10 its not available,but if you say you have windows xp it is there to download. Got it downloaded and have it installed.Acoustics in my opinion are much better in v1.71 tru a pa anyway in a band situation.

Hi I want to roll back firmware on jtv69s from latest version to old 1.71 ,however the monkey installer only gives me option to go back to v1.9 . How do I do this?. Thanks

JUST CHECKED MY FIRST JTV 69, IT HAS 1.71 FIRMWARE INSTALLED , BUT MONKEY WONT GIVE ME THE OPTION TO ROLL BACK TO THAT VERSION, WHY IS THAT?.

Hi I just bought a 2nd backup JTV 69 ,from my experience I rolled back firmware to v1.9 as acoustics sound better to my ears,however it still doesn't sound the same as my first jtv,even though it says rollback successfull.Any ideas anyone. Thanks.
