A few simple mods that can really clean up the sound from your EVJ. Part 1 cuts off abruptly cuz the whole video was too long, so watch part 2. I'm really just posting the video I was looking for before I started modding my EVJ and hope this will be usefull to the next guy.

  • Just did the jp1 mod, but surprisingly I kinda lost some signal instead of getting some gain. I get almost the same sound with the mod and the volume at 10 as i get without the mod and volume around 6 or 7.

    How? Why? Any advice?

  • @waarze1 It might be guitar. This jumper and corresponding resistor scrape higher frequency, cutting it should allow more to pass to the second pre-amp stage. If you're playing a "brighter" guitar like a Tele, etc. you might not notice the extra highs which could be overpowering the bottom end and making it "sound" quieter. I've found that I only use the mod at low volumes and others agree, w/other mods it sounds better loud with jumper in tact. Good luck and have fun.

  • Hey jak thanks for the great vid. One question, do you think it would be a good idea to install a 1/4" female jack instead of a manual switch? I want to try and use a foot switch with this. What do you think?

  • Hi,

    how about putting a potentiometer instead of the switch...to get something like a presence pot?

    Any risk to do so?

    Rgds,

    Eric

  • @jak442 tried it with several guitars now:

    the hights are there! THANKS!

    but the thing i dont get is: how can the signal be reduced in volume when i interrupt the jumper to a grounded capacity. this is what my logics says... i might be totally wrong since i ve never done anything with technical electrics - i dont even know how its called^^ (since im not an english native speaker).

    but thanks anyays!

  • Great video! Good instructions and high quality video. I'm gonna try it.

  • nice, very good instructions; modded my EVJ myself
