For those of you that have experience with the GT multi-fx unit, how would you rate the preamp? Separate rack mount power amp, 2 speaker cab configuration.

I know they're a little long in the tooth. Are there amp models or just speaker sims etc. as in many of the earlier units of this type? Sound quality? Noisy? Idea re: value?
Thanks.

Jerry, I'm still using mine that I got 20 years ago. The display went and I replaced it. The external power supply gave up the ghost but was real easy/cheap to replace with a generic unit as it is a 9V AC.
It has two cabinet simulation programs that I don't use now but have in the past.
At the time the unit was quiet compared to other digital offerings like the Digi-tech stuff.
It seemed to have more headroom than the Yamaha RV500 I replaced. I found it quite easy to set up.
Back when I was playing lap steel/pedal steel/6s guitar in a commercial country band I found it great for switching settings quickly.
I recall the sales guy saying it wasn't as "over the top" like the other multi-affects units that all the young kids were buying to get a shred metal sound mixed with reverberation effects.
The GT has the pre-amp with overdrive feature. There is a non GT version called simply Quadraverb if you don't think you'll need overdrive. I'd get the GT as you can always turn off or bypass the preamp.
I recall using the cab simulator to fatten up my lap steel sound along with overdrive. I got "good tone" comments from many players with that arrangement.
The bypass is a true bypass.
I think they can be had used for ~ $200.00 if you can find one. I think the display problem may have been systematic though and you may be able to pick one up for real cheap missing a row or column or two of display segments. I could guide you through replacing the display.
I think it is a very sensible unit for we clean players. for instance I like the way you can assign one of a few EQ settings to any or all of the other program selections.
Some dedicated reverberation effects units like a Lexicon are probably better in that department alone but the Quadraverb offers more sound variation at a pretty good quality.
I've been able to store all my personal settings on a computers hard drive via its midi interface to be recalled if the back up battery ever fails (not yet).
I've never owned the any of the Peavey multi-effects units but I'll bet it is similar.
I velcro mine to the side of my pacaseat - I've never had the the floor pedal unit for it as I have too much to do already with my feet....blah...blah...blah.. you got me going now.

BTW - I've always used it in an amps effects loop. I prefer the sound of my magnetic pickup hitting that first preamp tube in my amp. My chain is: guitar to volume pedal to amp input then amp effects out to Quadraverb and back in to amp effects return.

Thanks Jim. Yes, I'm familiar with the std. Quad. I know where one of these GT's is for pretty cheap so I was wondering about the pre-amp behavior mostly, for use in a rack system. Probably just as a back-up to my other brands similar units.

I'm used to programming multi-fx units, so no problem there. The info about the display failure is valuable too. I'll be sure and check out all the segments when I see it again.

TY, JO.

i loved it ,very handy,but it seems like there may be other option now,i used to play directly into the mix at small gigs,and no way is it the same as a small amp.
Some of the small pevey amps have great modelling on them now which are even better than the Quad,plus you get a small rehearsal amp.
my 2 cents worth.

Thanks Sam. I don't use a combo amp. Just a MosValve rig with a stand alone power amp so I require a separate preamp. I have a couple, but just considering the GT as a backup for the future.

Appreciate the input.

If you are using a Mosvalve rig, it's hard to beat the Blue Tube II for a pre-amp. You might even be able to find one with the steel mod.

Yeah, I know Erv. I got a couple of those already. I'm just looking for more info about the GT.

I have the original Quadraverd. I was not impressed with it. I have a Walker Stereo Steel, and with the quad I was not getting stereo with it. I bought a Pro Fex a week ago, and found out how user friendly it was. And it has true stereo on it. I put a couple of Newman presets in it. I still have the Quad, as a backup.

Tommy you may be right concerning the QV is not true stereo in that it takes one channels signal input and then works on two versions with different delays that get sent out the two, left and right, output jacks.
Are you sure you had different delays set up for left and right?
Since at some point all PSGs are mono (unless you run two pickups) I don't see the point of having a two channel signal chain from start to finish. I do see the point of having stereo amplification with two speakers. When you have different delays set up you get dramatic delay separation effects.
I have the GT version which has two jacks in and two jacks out. I suppose if it is how I describe, one of the stereo ins is a "feels right" feature that has no real consequence.

Yes sir I am sure. I got mine used at a pawn shop. When I had it hooked up and pulled the effect knobs on my Stereo Steel, it would come out of one side. I talked to Gerry Walker about it.I thought it was the cables, but it wasn't. I tried to adjust the EQ, and I thought it was the problem. I had stereo, when I would pull one knob out, and leave the other pushed in. The Pro Fex has more user friendly set ups.And has a great pre amp.
