Location: Boise, Idaho | The guy that bought my 99 Collector wondered if a preamp other than the Optima would eliminate the piezo quack on the bass strings. I did a little reading and didn't find an answer.
Anyone know if the newer preamps cause less quack. We've lost him now to the Taylor side and I don't know if there's any hope of bringing him back. |

Location: Flahdaw | That's why I don't "plug in" my '99 much. I'm so used to the warmth of natural acoustic that all electrified sounds harsh and quacky to me. I'm looking forward of the OFC get together this weekend so maybe g8r and iffy can show how to get a good, warm amplified sound. |

Although I notice it in solo applications, I don't really hear it in the band mix and nobody ever complains. |

Location: Orange County, California | an active DI, or high impedance pre-amp (Dtar stuff is good, Boss AD-5 works great).
Sometimes just figuring out how to run with the gain below 12 o'clock is all it takes to give you more headroom and a cleaner sound plugged in. |

| When the pre-amp died in my T****r, I put in a B-band and it was quackless. I eventually got tired of looking at the hole in the side of the instrument, so I got a new Fishman pre-amp and reverted. The downside is that B-band pickups only work with B-band pre-amps, so I don't know how well they could be adapted to Os and As.
I do know that B-band now makes a direct replacement pre-amp to fit in the side of the T, so I'll be retrofitting in the near future. |

Location: SE Michigan | I have a 1581 Adamas with an Optima preamp. I also am a pretty heavy-handed and percussive player. So far the best solution I have found is to use a Fishman Aura Dreadnaught pedal. I find setting 13 sounds the best. It really cleans up the quack and makes the amplified sound much richer.
That and trying to lighten up on my attack a bit helps, but that's no fun! |

Basically they exagerate an already huge response peak. There's not much that can be done to cure this (extra preamp headroom can help a little, but this is a design consideration rather than a twist of the volume knob) The fact is that Ovation pickups are among the least "quacky" but really it's the nature of all undersaddle pickups. Other types of piezos such as SBT's like the Baggs I-Beam or K&K don't have this problem, but the payoff is a significantly lower feedback threashold.
One way to tame it a little is to learn how gain-stages work, and make sure your entire signal path has plently headroom. |

SBTs are a HUGE compromise, IMO based on experience. They work well only when blended with a UST, and then only in a small percentage of the total signal. |

Location: Scotland | Of Course they're a compromise, and that was my point. If you use an undersaddle there will be a certain amount of "quack" and that is one compromise. Use an SBT and you have a different compromise. Use a soundhole magnetic there will be another different compromise, and stick a mic in front of the guitar and have a few more compromises. Blend any combimation of the above and you can get a really good sound, but it's still a compromise compared to the ACOUSTIC sound of the instrument.
These are the choices when you perform to an audience with an acoustic guitar: hire the finest microphones, sound engineer, sound system and venue money can buy, or play acoustic and keep you audiences to less than a couple of dozen, or use some kind of pickup and deal with the compromises. Life just isn't fair. BooHoo. |

In compressor terms attack determines how quickly the compression kicks in. A slow attack setting would be used for sounds that do not have fast transient peaks (bowed instruments or wind instruments played legato for example) but anything which is struck such as drums and plucked or strummed stringed instruments have a huge attack spike, and it's this that contributes to the quackiness. So you want the compressor's attack time towards it's fastest setting or it will miss the transient. |

Location: Colorado Rocky Mountains | Thanks, Paul. That explains why the slow attack compressor isn't effective for some models, while the fast attack does work. The Trace SMX two-stage compressor provides this flexibility with its dual compression (fast and slow) features. Oddly, every model seems to have its own quack threshold and different response characteristics to compression. It really pays to understand how everything in the signal chain impacts output, or like me, surround yourself with good sound engineers. |

Location: Nova Scotia, Canada | I run all (4)of my O's into a L. R. Baggs Para Acoustic DI and they sound super...no quack. I would like to try a tube outboard DI but I so rarely play acoustic plugged in that, for me, it's hardly worth the bother.
Do you stock any of these Baggs units, Paul T? |

Location: Scotland | I own a couple of Baggs Para-coustic DI's but I don't stock them. They're a very nice unit.
The new Baggs Venue acoustic processor/DI is worth checking out. |

Location: Scotland | Mark, if I'm not mistaken the 99 Collector has a Thinline pickup. Unlike the original Ovation pickup the thinline is variation on the pressure-sensitive undersaddle type. That pickup is not doing him any favours in his quest to be quackless. |
