    Hey all, my 2000 Modulus Quantum 5 string Bartolini set up has taken a crap. Anyone know of a specialist in SF Bay Area, preferably SF itself or the peninsula that could handle this for me. Tony Cimperman (new Modulus peep) has been great in responding and recommended Joe Perlman himself out of Stockton, CA. Tony actually sent info and pics on a pre-wired Bartolini pre amp set up that is almost plug and play they sell also.

    Thanks

    what exactly is the issue at hand?

    do you know what exactly 'crapped out'? are the pickups malfunctioning or is it the preamp?

    (i always change the batteries first to make sure i eliminate that option. can't count how many times it was the battery that somehow drained)

    if it needs to be replaced, are you looking to buy the exact same setup?

    if you need help in the city, you can't go wrong with the cats at sf guitarworks. i've had quite a few projects go through their doors. i basically became known as 'mr. modulus' since all my work needed was on modului or g. gould releated.

    if you prefer the south bay, my choice is keith holland's guitar hospital in los gatos. very knowledgeable staff. quick turnarounds and work is decently priced.

    Hey, thanks for the reply. I am not sure what exactly is wrong. It started sounding horrible like it does when the batteries get weak, so I changed them. But now, no sound at all. If I move the volume knob up and down, very slight scratchy noise and it causes the compressor to kick in on the input of my Eden Nemesis. I saw sfGuitarworks listed on Bartolini's website so I'll head on down there. Thanks again!

    My guess is that the connections to the pots need to be redone. I've worked on at least one Modulus of about that vintage with the same problem with the Bartolini electronics. After clipping and reconnecting all the wires, everything is good again.
