StereoSteel/ProfexII "Settings"

Ed Iarusso · From: East Haddam, CT US of A

I use the above units into two 15" Marrs cabinets, with a Goodrich 6A Super Sustain Match box on my guitar leg. I am questioning the minimal range of ajustment (settings) on the Profex. I run the output level on the back of the Profex at 4 (11:00) and the input on the front of the Profex is barely "on" at about 7:00. I have a factory circa 1993? Lashly LeGrande. Why is it I have such a minimal range of control on the Profex? Without the Goodrich unit I get wicked break up or distortion, even at low volumn if I'm not real careful with the Profex settings. With the Goodrich unit I run it at about 12:00. Can anybody help?
Thanks to all of you who respond. The convention was great!

Ed,

It sounds to me that you are overloading the input to the profex. I run from my steel to the profex at a level of about 12 oclock. This makes the green led on the unit flicker to on constantly. Check and see how much gain it takes on the input of the unit until the light stays a steady green. Then adjust the output of the Profex.

Anytime, you barely "crack" a volume controll and you have distortion then you are overloading the input side of the unit. There are also settings for volume internally in the Profex on each of the effects and depending on what you are doing you might be overloading the effect chain as well. Try going to a very basic patch in the Profex and see what that does.

Good Luck

Best Regards,

Thanks for the reply Mark. I also thought the Profex input is being overloaded, but from where? Is it from the preamp gain control on the Stereo Steel amp? I will try some different settings and see what happens.
Thanks again, Ed

Ed- give Gerry Walker a call- he's very helpful, knows the Profex fairly well and designed the Stereo Steel-- 619-460-5008

I talked with Gerry at the show, took his suggestions, tried them...... and continue to experience this condition. Gerry said I should be able to run the Profex output allthe way up, loose the Match Box and adjust the Profex input accordingly. No way!
The Profex output and input are still extremely "sensitive". (I really have to watch my language, in front of them). I end up using the Match Box as a "throttle" if you will. Oh well.What next?

I think if you're not running the ProFex II in the effects loop of the Stereo Steel, you should be.

I downloaded a copy of the ProFex 11 manual from the Peavey web site. The basic instructions say to start with both the input and the output off, first turn up the input until the green led filckers on and off, then turn up the output to get the desired volume. On mine, the input is about 12 or 1 o'clock, the output is about 8 o'clock. Probably the best thing would be to download the manual.

After reading the posts( all the above) I am seeing a thing that suggest maby the pick-ups are too hot. I have BL-705 pickups on my axe and run the profex II at about 12:00 and 12:00, and expericence no problems. I have tried other pick-ups and noticed a marked difference in the distortion/sound.

I remedied this by changing the input resistor to ground at the pre-amp section of the amp. After satified test of this, I returned the resistors back to its original value.

Sometimes, in our effort to get a better sound (in our opinion) we perhaps over-do the pickup thing. IMOHO "Hotter is not always better".

Look at it this way too. If you have to run the volumne control almost at 0, you are not getting the full dynamic range of the pick-up, and at best, the overall sound isn't what we wished it was !!

Ed, have you tried using a reqular amplifier, to see if it might be a problem with the way you are connecting to the Stereo Steel amp? Ed, try the Goodrich unit, to the ProFex, then to a different amp. Sounds to me like the Stereo Steel unit is not able to take the line level signal coming out of the ProFex.

Yes I have tried other amps. I was using a Webb and Nashville 400 as a stereo combo through a Boss SE 50 and input/output levels were never an issue. I would have quite a range of setting available. My guitar is a "factory" Lashly LeGrande. (not a II or III). I never changed or modified the pickups. Exactly what they are I would have to determine that. Thanks again to everyone who has responded. It helps. Eddie I

From what you just said Ed, it seems the signal does not get distorted until the Stereo Steel is added. Is this what you are saying? Is the Stereo Steel input designed for a instrument level signal,or a line level signal? Could you find this out? If it is designed for a instrument level signal, any type of pre-amp feeding it could overdrive the input. This is something I would really like to know.

I run my Boss GX-700 in the effects loop of my Stereo Steel, as I suggested in a previous post. I run the input volume (the small knob by the input jack) of the Stereo Steel only about 1/4 open, or at 9-10:00 on the dial. I still haven't been able to turn the master volume up past half way without blowing the doors off, and have NO distortion.

Jim, i'm going to try different setting on the stereo steel. I've typically run the gain control at 12-1:00 and the master output at 1-2:00. I'll try the gain backed way down to 8-9:00 as you do. I'll see what that allows me to do with the profex input and output. Thanks again, Eddie I

BTW I patch through as follows:the Profex outputs to the SS returns the SS send to the Profex input My guitar is to the SS input.
This is per G D Walkers instructions. and...if I remember correctly when I first got the SS I did try going through the Profex Effects loops and got nothing. (That was when I picked up the phone and got hold of Mr Walker)

If you are using the Profex II as an effects processor only(and not as your preamp), I suggest that you connect it into the effects loop of your Stereo Steel rig. The input of the Profex II is for instrument level and not line level, so the front input will clip sooner with a line level signal plugged into it. When you connect it into your effects loop, you may have to pad the signal down if it is too strong for the input.

It could also be that the output of your pickups are too hot for the input of the Profex II, but I don't think so as I haven't run across that symptom yet.

The GLOBAL volume control of the unit would probably not cause the symptom that you have described, but the input sensitivity control adjustment would.

We're getting there! I've backed down the SS gain from 12:00 to 9:00, backed off the SS master gain some, lost the Match Box. This has allowed me to up the Profex input up to about 10:00 and I'm getting more dynamic range out of my guitar. The true test will be this weekend. I have an outdoor gig. Thanks to everyone for their help. I'll let you guys know how it goes.
