Solid state AMP
Looking for a solid state AMP that's a tube-alike sound..
I want something versitle that can sound vintage and Hi-gain I choosing between Peavy xxl combo or Tech 21 trademark60 any suggestions? thanks.. Ka-el |

Ka-el I just got rid of my Tech 21 because I bought a Vox AD30VT. It also comes in an AD50VT which is comparable to the Tech TM60. Here's a link. Good luck. http://www.voxamps.co.uk/products/va...15vtad30vt.htm Jim -- it is better to remain silent and be thought a fool, than to open your mouth and remove all doubt.... |

You want a tube amp sound live - you get tube amp. Thats one thing im sure  kisses. |

Check out the Vox modeling combo amps

Take a good SS amp, and ruin its low output impedance with a series power resistor whose resistance is in the 0.33 to 4 ohm range. That will give you a fair approximation of tube amp sound. |

No. This will approximate the load the speaker sees. But with a guitar amp, you are normally running the amp well into the nonlinear region. That's the whole point of the thing. And the nonlinear region is totally different between a typical tube and solid state gain stage, plus the tube amp has an output transformer (which is usually undersized so it can be overloaded). I have seen some FET-based guitar amps which use output transformers, in order to get similar effects to the output clipping and transformer overdriving of a standard tube guitar amp. I didn't think they sounded all that great, though. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Agreed that tubed amps that are designed to be EFX devices can be effective as EFX devices. I have seen some FET-based guitar amps which use output transformers, in order to get similar effects to the output clipping and transformer overdriving of a standard tube guitar amp. I didn't think they sounded all that great, though. I suspect that the way to most closely approach the sound of a tubed amp that is designed to provide EFX would be to use an accurate SS amp combined with a complex (perhaps digital, even computerized) line-level EFX generator. |

Been done. Doesn't really work very well. The nonlinearities in a severely overloaded guitar amp-speaker system turn out to be quite hard to model. They include not only active device overload (preamp and power stage) but passive device overload (transformer) and back EMF from the speaker making its way back into the amplifier. A highly complex dynamic system, one which we really don't have a handle on, at least not well enough to model it. Peace, Paul |

Good luck. http://www.voxamps.co.uk/products/va...15vtad30vt.htm I have a Tech 21 Trademark 10 I've been continuously happy with. If you go with a Vox AD50VT (or one of it's smaller brethren) make sure you play it first. The one I played through had a lot of noise in the preamp, no matter which 'voice' was selected. Keep an ear out for it. jtougas listen- there's a hell of a good universe next door let's go e.e. cummings |

On a bad day you have this big multidimensional lookup table. Collecting the data may be a lot of work, but it can be done. |

No, put half a 12AX7 (or two halves as a "Darlington pair") as the last gain stage after the preamp. Works great. -- Les Cargill |

Something about time spent developing and testing tube amps in the day of. |
