I just picked up a '66 Bandmaster head and cab with the original Jensen 12s. (Ain't it cool - real '60's vibe). The cab is closed back. When I opened it up to check it out, I found what looks like pieces of insulation stuffing inside. This is my first old Fender closed-back. Is the stuffing stock? What does it do? I suspect I should remove it. Any info, thoughts, suggestions appreciated. Especially if you know something about old Fender cabs. Thanks, Bill, tgo

Love the paisley Bill. I've never experienced a closed back instrument speaker, but the sound generated by the back of the speaker cone has nowhere to go so needs to be absorbed; hence the stuffing. So I'd leave it there: I would imagine it'll be less efficient (quieter!) than an open backed cabinet. Mark |

The stuffing makes it act like a larger box. It may need to be replaced if it's falling apart, or you might want to even add a little. Awesome amp, by the way! John |

I am in awe of the extreme grooviness of that rig! What a find! A physical & emotional match for Woody, Irv OR the '61 Strat, I would think. Should you ever want to unload it..... And yes, every closed-back cab I've ever opened had the insulation - leave it. Peter |

Am I the only one who gets annoyed with most cab makers for almost always making cabs slightly smaller than your normal rack/head unit? Does it have something to do with the # of cuts out of a standard sheet of ply and not wanting to waste wood/maximize profit? Cool stack Bill- sorry for the anal retentive hijack, but it's always bugged me and around here somebody ALWAYS has the answer! |

Well in this case Toby it is the owner of the equipment that has created the mismatch. :-) This cabinet was intended to be used with the speakers set horizontally. I've see this occur with other brands also where the owner sets the cabinet vertically. Keith |

Yup, off white/yellow fiberglassish. Each speaker has 4 pieces, about 12-14" x 6", just laid across the back of the speaker. I've been poking around the net and have seen some suggest that the foam should be mounted on 3 continuous surfaces. Is this preferable, or is is just as effective to leave it covering the speaker backs? Bill, tgo |

Were you seeing the paisley before you touched the mysterious cabinet stuffing, or did it appear shortly thereafter??! Larry |

I've never seen the insulation laid on the speakers - always attached to the sides & back. Peter |
