Vann; Jan-olof is an amazingly nice guy. He played a superb set at Bass Day Uk several years ago then got sidetracked by the three Alembic players that went along. Needless to say, instead of heading off to the performers private area, he spent the next couple of hours chatting and drinking with us. We also managed to lure Trip Walmsley into the conversation with promises of Beer. Jan-Olof allowed me to play his custom bass with Alembic electronics (albeit not plugged in) and it was an excellent feeling instrument.
We did have a chat around his electronics and he did state at the time that they were 36 volt which we thought was strange. He wasn't using a power supply as he felt there was the potential for a catastrophic failure which wouldn't happen using batteries.
