1477.0. "QSC Power Amps" by HAZEL::STARR (LGTFOOH) Thu Sep 14 1989 01:22

I'm looking at rack-mounted power amps, and a friend of mine keeps raving 
about his QSC powe amp. Anyone know anything about these amps? He said he can 
get a new one for me for ~$400. Its solid state, and runs 100 wpc.

Any more info from you guys?

> Alan is that Eddie tellin you that?

Yeah, it was. He's *real* happy with it, and it seems to work great with his 
MP-1. But I just wanted to know if anyone here had any opinions on them (ie. 
reliability, value [bang for buck], comparative amps, etc.)

1477.4great power amp!HAZEL::STARRWe're beating plowshares into swords...Thu Nov 02 1989 16:2812
Thanx for the info Mike. I got some recommendations for the QSC amps in the 
COMMUSIC file, and from my guitar teacher (who has one in his rack). I ended 
up puchasing a QSC 1200, which is 100wpc, or 150 watts in mono. This is a real 
nice, clean amp (solid state). It takes up 3 rack spaces, and cost only $325 
used.

I'm currently running from the guitar into a Chandler Tube Driver, then into a 
Digitech RDS3600 delay, into the QSC. Simple, but very effective for what I 
want, and nice and portable. I play it through a 4x12, but can use the rack 
with a smaller cab if need be. I'm very happy with it!

    How are these amps?  I got rid of my Carvers a few months ago, now
    I'm looking again.  Any one no of prices?  I'm looking for two amps
    at about 250 watts and one at about 100 watts.

Volume.

That's it! (And IMO, that's all a power amp should have!)

    Agreed.  The MOSvalve has presence though.  I don't know that
    this is necessary.

    I think you're both nuts!  The key to any REAL tube output stage is the
    presence circuit!  If you want a good PA-type (clean) sounding power
    amp, vol knobs are all you need (sometimes not even that!), but for 
    guitar purposes you NEED the presence!!

1477.11But I see your point...GSRC::COOPERMIDI Rack PukeTue Dec 11 1990 17:235
    Real men use preamps for tone, power for loud.   
    
    ;)

    Anyone who thinks the tone comes from the preamp stage is an idiot!

Who said anything about tubes??? Solid state (for a power amp)!

Power (imo) should be just that - power! It shouldn't change the tone at all 
(or at least as little as possible). All its there for is to amplify the input 
signal.

    	Boys, boys, boys...  Don't confuse hifi and guitar amplification.
    	The resulting tone from *all* contributors is important in guitar
    	amps, but straight, clean amplification is the goal for hifi.

    re: Power Amp coloration
    
    Think about it. If the power amp didn't color the sound, everyone
    would just use the cheapest, most reliable power amp they could
    find. Discounting snob appeal, folks buy what sounds good to 'em,
    not the cheapest.
