    MM SR4 2007 pre-amp

    Good afternoon!
    I'm new here and sorry for my very bad english but I don't speak/write in english since 2009...
    I've bought a MusicMan Stingray 4 Strings built in 2007 and now he makes me some problems. After 7sec of playing the volume turn off... I replace the OpAmp with another one like first one. Now I have 1/3 of volume and a bad distortion... What can I do? Oh, a little detail, I'm italian... (I hope to have explained good! )

    oh, I think that the problem is in the Pre-Amp Section, but I can't find the electric diagram!

    or call mogar music, the mm distributor in italy.

    they might be able to help you out

    MrM
    just put flats on the bongo!!
    just put roundwounds on your fretless!!

    eb customer support:
    E-mail: musicman_customerservice@ernieball.com
    Telephone: +1 866-823-2255

    trussrod adjustment:
    Click here for an image!
    less relief / flatter = lower action
    more relief / bow = higher action
    do NOT use cheap tools to adjust with. they might break and scrape up your pressious!
    also, if you are lucky enough to have a 100th namm sr4: the truss works the other way around on that one!
