Bassbreaker question

Long_Ghost · August 28th, 2003, 01:12 PM

Although this is not my main rig I do enjoy the beefy tones.The problem I am experiencing is whenever I hit a large D chord the cabinet begins to resonate and will eventually begin to howl. I have tried stuffing some foam in the cab.,but to no avail.I really do enjoy this amp and if I could stop this minor annoyance I would be truly happy.

Any help out there?

Many cabs will do that atleast on one note , be glad its not on E that makes it resonate ! I had a bassman that had a really bad cabnet buzz on E. At practice I could sit on the amp and it wouldnt buzz but not cool to sit on it at gigs ! Now alot of the tunes we did were in E so we decided to tune down to E flat until I could get a different amp! Are you sure its the cab resonating and not something else in the room ? sit on the cab while playing and see if it goes away!

I don't know that sounds a little too kinky for my taste!

It is definately the cab and it has to be cranked pretty good to get it going,but does it every time I hit a D note/chord.The rest of the scale sounds great though.

Well, I'd say just grab a screwdriver, and have at every screw you see. Just make sure you don't overtighten. You're lucky in that Bassmans don't have reverb, so that's one less thing to worry about, but check all the screws around the speakers, and then check the handle, chassis screws, and anything else you find including tube sockets, and anything else sticking out inside the amp. Then, if all else fails, take it to a tech. It's a "custom shop amp" right? I would hope the Fender custom shop would have an interest in helping fix the problem.

Tighten every screw in sight... If that doesn't help, bring it in to a good authorized Fender dealer(under warranty I assume?)
BTW I LOVE that amp. That is just a killer, killer amp. One of my all time faves actually... I wish they made it as a head and cab, I'd probably even buy one new!

Uh well actually I added a bias pot and I believe
that may have voided any warranty issues.
It has been taken apart an inordinate amount of times
so I will attack it with a screwdriver post haste.
thanks for all the info .

I've heard conflicting stories about the Bassbreaker. Some say it's a PCB amp like the Bassman reissue. Others say it's a PTP amp like the Dual Pro and Vibroking. Which is it, once and for all?????

Long_Ghost · August 30th, 2003, 09:53 AM

definately a printed circuit board,although there are
PTP kits available.
Hope this helps.

Yo Ghost,

Thanks for putting this question to rest. I suspected it was an inexpensive PCB amp like the RI bassman, but just wanted confirmation.

I'm aware of the aftermarket PTP kits. I have a Hoffman kit in my RI Reverb, and it's better than the stock PCB. Not too hard to install.

It's PCB, but PCB or PTP - It's a great sounding amp in a beautiful cabinet..
