| 1381.1 | Boogie Preamp has one built in | ANT::JACQUES |  | Fri Jul 14 1989 08:27 | 11 |

    I saw the ad for the GT unit, and choked on the price. 
    For $500 you can buy a Mesa Boogie Studio Preamp, which 
    has a builtin speaker-emulator circuit. Rick Busenbark
    is the proud owner of one of these. I would like to demo
    one. I just happen to have two empty rack spaces in my
    rack.

| 1381.2 | ... it's emulating a speaker, I know... | NRPUR::DEATON |  | Fri Jul 14 1989 14:54 | 4 | 
|  | 	What is speaker emulation?

| 1381.3 | Direct Box With Color | AQUA::ROST | It's the beat, the beat, the beat | Fri Jul 14 1989 14:59 | 10 |

    A speaker emulator is a box which allows you to go from the speaker
    output of an amp to a line level input; i.e. a direct box which
    "colors" the signal the same way a speaker would.
    
    It's two prime uses are recording/sound reinforcement applications
    to avoid miking amps and for use in a amplification system where
    you generate the guitar amp "tone" by using a small amp, then crank
    the line level "enmulated" signal into a super hi-fi power amp/speaker
    combo.

| 1381.4 | could it be....? | VIDEO::BUSENBARK |  | Wed Jul 19 1989 08:50 | 22 | 
|  | 	Hm.... However a speaker emulator on the Boogie is very
different from what GT is selling. They seem to describe this 
$450 gem as an active load box with tone controls which would provide 
an overdriven sound.(this is like a bandmaster wide open in a 4 12 cab)
	The speaker emulator on the mesa is colored differently
from the main outputs but is a preamp out not the output of an amp
loaded down.
	GT must be using a stepdown xformer/resistive load and then putting
it through another preamp stage or something. They probably use negative
speaker energy to add some tone(presence)
	It's interesting that Aspen makes a distinction between yesterday's
player and today's with perception of distortion. Now maybe people will realize
why these old vintage amp's are worth so much. Not to mention the level
of complexity that music performance has become with all the hardware
available it really is mindboggling. I still think there is beauty in
simplicity...
BTW 2 space's for the Mesa is not enough... You need a space for 
cooling.....

| 1381.5 | A happy GT owner | KIPPIS::LEHTINEN | He's here! The Phantom of The Opera... | Sun Jul 23 1989 08:44 | 25 |

    I have GT's rack mount preamp/poweramp w/ speaker emulation. 
    Both amplification stages use tubes. The power amp is 25 W's 
    and the speaker emulation output comes after that. There is 
    also a standard line level output after the preamp and an
    output after the power amp to drive a speaker cabinet. 
    
    I have been extremely satisfied with my GT. I have previously
    owned a 100W Marshall with master volume, a 12" Mesa-Boogie
    combo, and a VOX AC30. Because I work allmost 100% in my
    home studio for me the GT was a dream come true. It's so
    easy to work with in the studio. I can get more gain 
    (i.e. more distortion) out of it than I got from the Boogie.
    I used to drive the Boogie with an external preamp but the
    there is a limit to how much gain can be obtained before the
    hiss and noises become too loud. The GT is the cleanest amp
    I've heard so far. 
    
    I have also tried the Hughes-Kettner Cream Machine. It was
    _very_ noisy. Also since it's just a preamp the character
    of the distortion and quality of the sound wasn't anywhere
    near that of the GT.  Albeit the H-K is much cheaper.

| 1381.6 | GT Speaker Emulator seen? | XERO::ARNOLD | Sarcasm, Unlimited | Mon Mar 05 1990 11:34 | 16 | 
|  |     re: .0
    
    >>> Groove Tubes Speaker Emulator
    >>>
    >>> Probably an expanded version of the speaker emulator in the GT preamp.
    >>> Single rack space, a couple of knobs.  Reviewed in the new GP. 
    >>> $450 !!! sputter!!!
    
    Has anyone seen one of these in a store.  (Preferably in the MA/NH/RI
    area.)  I'd like to try one to compare to the cheaper alternatives. 
    I've read the reviews of the circuit in Guitar Player and want to (a)
    try one and (b) see if anyone discounts them.
    
    Thanks for any pointers (local or distant),
