| I have wanted one of these amps for a couple of years and finally bought a new one last week. Up until now, I've been playing my Stringmaster through a HotRod Deluxe and liked the tone I was getting until my volume swells would cause it to get dirty. That's fine if you want that tone but I like it clean for Hawaiian and Swing so I sold myself on getting a more powerful amp. My question has to do with the hiss level of the Twin and whether it's normal and typical of this big beast. Plugged into the Vibrato channel, volume set at 3 or more, the hiss (white noise sound) is noticeable and on the Deluxe I never noticed this. I'm not talking about hum here but you folks know what it is that I'm hearing. What's up with this; is the bias out of sync or do these amps just idle a bit noisy? What are some settings you players like on the Re-issue Twin? |

Eric,
I had one in for repair awhile back but
didn't notice that it had that much more
hiss to it than any other amp, really.
The bias would have nothing to do with
the "white" noise you're referring to.
What settings are you using? Pretty
much the same as your Deluxe? Bright
switch set the same? Could even be
a noisy preamp tube. Do you have the
same amount of noise from the Normal
channel as the Reverb channel? |

Erik....
All tubes are NOT created equal !!!!!
Eventho they may be of the same brand,number(12AX7),they differ in even production runs. I would suggest you try several different tubes,vendors,before givin' up on the "white noise". Some tubes are "Microphonic" (meaning the elements inside the glass envelope are not stable and move around "microscopely") and lets face it,Nowadays, the quality control of off-shore manufacturers isn't anywhere near what it use to be with U.S.A. manufacturers. Like G.E., R.C.A., and Sylvannia use to be. Sadly,the tube as a sound device will demenish to the point of non-usuable.[This message was edited by Bill Crook on 23 June 2001 at 06:00 AM.] |

| Swapped out the stock Groove Tubes 12AX7's with Amperex Bugle Boys...still the "white noise". Have tried every imaginable setting...still the "white noise". Same on both channels. Guess I'll get used to it eventually. |

Eric,
Gee Whiz...if you've only had it for a
week, & you don't think it's 100%, then
take it back for a refund or exchange!
There shouldn't be any more hiss than
your Deluxe. You paid good $$$ for it
& you ought to be totally satisfied.
New amps shouldn't have "problems" that
you have to get "used to".  |

| The T/R amps have what is called a "negative feedback" circuit that helps eliminate the hiss. Could be that you simply have a bad resistor or capacitor. (The hiss also increases a lot when the bright switch is used.) |

| Try an Evans amp, I know they ain't cheap but will be the last amp you will ever buy. Made totally for Pedal Steel Guitar so there are no compramises. |

I agree that you should return the amp for a replacement if possible. It is likely bad tubes, or could be a bad cap. Rather than try to locate the offending member by process of elimination, just swap the whole amp. If you can't do this, I'd start by swapping ALL the tubes out. Most people agree the tubes that fender stocks in their new amps are junk.
A twin in good tune should be close to DEAD quiet at idle, even when cranked. Don't settle for any less.

| I appreciate the input and advice. I'm printing out this post and with the Twin in tow, will be visiting the Fender dealer this week. Thanks!! |

The lead guitar player I work with bought a reissue 65 twin last year. His was a lemon also. It would break up at small club volume. He took it in for repair and got it back again with the same problem. In the end he got his money back. Since then he put a retro kit and new speaker in his 1976 session 400 and is happy with the old bomb.

Eric,
I hate to tell you, but the reissue twins are kinda known for being a little noisy. Search on the amp discussion boards, there are fixes for it. |
