J-TONE "John East" preamps

[kiat]

Hi, about a year and a half ago I bought and installed a new (version: Volume/Blend/Tone) J-TONE into my Lakland JO5.  Although it's been stable and I can mostly get the sounds I want, I'm pretty certain I'm not getting the best out of it yet, nor is the battery life great.  If you have or have had one, what are your impressions?  How much tweaking did you do? Do you use Passive often and when do you?  Are there some pedals or other things in your chain that doesn't like Active being on? 

 

Things I'm considering

• getting into rechargeable batteries and installing a permanent charger extension cable neatly into the bottom of the bass through to the cavity
• fully trying out the various adjustments that can be set, interoperating my amps and IEMs
  • frequency wheels
  • plug-in tone cap
  • bass control (boost/cut or boost only)
