| 1381.1 | Boogie Preamp has one built in | ANT::JACQUES | | Fri Jul 14 1989 12:27 | 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.

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 12:50 | 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.....

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 14:34 | 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),
