For a long time, I insisted on having a tube pre. I call it my purist period... but I tried a GK head while doing a comparison of rigs at a local Guitar Center, and I noticed that the GK SS head was a lot faster than an Ampeg tube pre and an Alebic pre... while the tube pre's were buttery and pillowy soft, the GK was quick and hit harder in my opinion. I've had An Alebic, a Demeter, a Navigator, and an Avalon 737, all with tubes... this SS Quest is noticeably different and IMO has that same fast attack. It's just as "good" and in some ways better. I really like it's simplicity. The EQ section is easy, and it's hard NOT to dial in a good tone that will work for jazz, funk, r&B, and especially gospel.
I'm glad that I got it. The price was right (From MF, of course), it looks good, and FOR THIS PRICE, it's better quality than a number of pre's on the market and more than worth it's light weight. Pair it with a decent power amp (QSC RMX for exaple) or a better quality one like a Crest CA9 or Stew 2.1 (higher power for headroom and all the little nuances of your playing) and this is a definite winner.
The highs are good and crisp, the low end is not wooly or woofy, it's clear and plenty articulate. The mids will definitley get you heard if that's your thing and dialing them lower (my thing) doesn't compromise the quality of the tone. There is a little bit of hiss, but it is a VERY little bit. Dialing down the highs and the treble on your bass will get rid of this as well as turning down the tweeters on your cabs if you have that option.
Drawbacks are: as I've said before, it should have come with rack ears.... in addition, it defaults to EQ channel 2 everytime I turn it on.... the pictures at the MF site and at the Epifani site show a limiter, it doesn't have a limiter... there is a button for either 3k or 6k equing on EQ channel 2, the difference is hardly noticeable. If you can hear it, your ears are better than mine. Could have left this off. The mid scoop button on EQ channel 1 is a bit extreme for my taste. I leave it out.
None of the drawbacks change the fact that this is a really good preamp. It is a set it and forget it kind of device. I don't see this thing failing me on a gig... I just can't get a bad sound with it.
