Hi Mr. Bonilla ! I got one unit, like yours. How did you manage the patch data, on battery replacement? Did you lost your presets or had any issue with the 3v battery replacement? There's some mod or a new way to realocate the battery ? Great video. Cheers form Viamao City - Brazil. 👊😃🎸🇧🇷
Hi Elias thanks for your answer, unfortunately you will loose your presets by replacing the battery. By not replacing the battery you will loose them too one day. As shown in the video, purchase a battery with the soldering pins. Unsolder the old one and replace it with the new one. Solder and that’s it your done and ready for 20 years. Cheers from France and i love Brazil 🇫🇷🇧🇷😊🎸
@@DBGUITARWORKSHOP Hello Mr. Bonilla. Thanks for quickly reply my question. Sadly, here in Brazil, purchase a new part for any device, sometimes is so very hard mission. I'm gonna try to dump the data via midi device, then make some alternative mod, for battery replacement. With battery AAA or 3v socket and solder some wiring. Is not so professional work, but functional in some way. The battery leakage is my worst nightmare. Can an aditional 3v battery connected in parallel override or erase the Eprom data? I'm afraid to mess up with the C. I's. Well, keep making more videos, the contents are so great and have huge information and knowledge. I'm so thankful for your atention and dedication to us, guitars and gear lovers. Long life to your channel. Excuse my sloppy english... Rock on!!! Cheers from Viamao City - Brazil 👊😃🎸🇧🇷
@@eliasfigueroa8791 thanks for your message and try it with battery replacement and some wiring if you are not able to find the part. Battery leakage can happen. But remember you will not loose the factory preset they are stored in hard in the chips. So whatever if you remove the battery for replacing. When restarting it make a factory reset. Hope this help good luck 🎸

Biasing is for power tubes !
That’s right cheers 😊🎸
Dont you need to adjust the bias when you change the tubes ? I got a JMP1 too and would like to change the tubes for myself
Hi, no you do not need to adjust the bias especially if they are brand new as I did.
