Complex tone suckage problem

Hey all...I'm currently running a stereo setup with a Fender Twin on one side, and a Peavey Triple XXX on the other side. My pedal board is pretty massive, and at present, I'm running a Vox wah into a Boss SD-1 into an EHX Polychorus out front -- the Polychorus splits the signal. One one side of the split, the signal goes to a Boss DD-5, and then to the Twin. On the other side, the signal goes straight into the XXX, and then out to the FX loop -- an Ernie Ball VP Jr, a Boss PH-3, another DD-5, an EHX Holy Grail, and back to the amp.

 

Now, most of you are reading this and saying to yourselves, "You're having tone suckage problems? No {censored}." It's not quite that simple -- all I'm looking for is to clean up the signal to my Twin. I miss that sparkle when I plug in direct. The problem is, I've tried splitting the signal directly in front of the amp (so that the only amp running any FX is the XXX) with a Morley A/B splitter and I still have plenty of signal loss and white noise.

 

What gives? I can only figure that because the two amps are linked by the splitter (and the XXX is loaded with FX), the signal to the Twin is somehow being loaded by the signal to the XXX. Anyone know how I can prevent this? Would a good pedal power unit help this? A power conditioned surge protector (I will admit, I'm using my Boss Tuner to power all my Boss pedals as well as the Vox wah with one of those One-Spot 9V adapters)? I want a second opinion before I throw down money on any of these things.

 

Thanks!

where are putting the a/b? to keep the signal clean..it would need to be ran first with A going through the pedalboard to the peavey and B going directly to the fender...if there is still noise then you may need a better a/b...I have heard the morleys can have some affects on your tone.

I don't use a 2 amp setup but seems to me the major tone suckage comes from your pedals. Not one of them is TB(aside maybe the PolyC; then again, you're using it to split the signal) and I know the boss DD-5 sucks the blankets in your a-hole hard.

You could either use a TB strip for all the pedals in front or a good buffer at the end of the Twin chain. A lot of buffer type pedals are available. I've been using a zvex Super Hard On with excellent results.

I'm sure someone can come in here to help you out more then I can..

Good Luck!

So you have:
Vox Wah
|
SD-1
|
Poly Chorus
| |
DD-5 XXX
|
Twin

Does the Twin's tone improve when you unplug the xxx from the Ehx?
Does this problem occur when the chorus is on?
Splitters can cause problems with tone.

Break it down. Start by plugging strat into the Twin, then add the sd-1 and dd5. Listen for changes in tone. Add the wah, then the chorus. Then add the xxx to the chorus and see if that affects anything.

Vox wahs are tone killers also, unless it's been converted to true bypass.

Seems to me it could be related to the fact that you've got 2 amps that aren't isolated from one another; they are directly connected via the chorus. I tried to do a similar thing one time, I had an ABY with clean on one side and dirt on the other. The ABY, being not completely isolated A vs. B, had all sorts of "crosstalk" from the dirt side over to the clean side.

I bet if you used some sort of amp switcher (I'm thinking of the Lehle, but I'm sure there are others), you'd solve a lot of your problems.

This seemed like the most likely problem to me, at least given the experiments I've done with my setup thus far -- and it's too bad, because I really love the sound of that Polychorus split...

What you need, then, is an ABY with stereo inputs, buffers (to prevent loading effects) and isolated outputs, then a separate supply for any other pedals on the Twin side.

This seems like a good solution -- any other recommendations for an ABY? I checked out the Lehle.

To your credit, you advised him what he might need w/o plugging your own product. Only upon further questioning did you spam yourself. But in the future.....KEEP IT IN THE SPAM THREAD. :mad:


:D

Well, it's a vague term, but typically used to describe loss of volume or treble. Though I suppose it's just used to refer to any degredation in sound quality.

Specs and price?

I just discovered Startouch via a review of a Lehle switcher, and though their pedals aren't buffered, their A/B/1/2Y might suit my needs regardless.

Okay, one more question -- I emailed Startouch about their pedals, and the guy said that typically the pedals don't have isolated outputs, but he could build one. However, from the way he described the actual functioning of the pedal, he made it sound as though once both paths are activated, they would no longer be isolated.

Is it possible to avoid hum if I almost always leave the Y path enabled, or am I doomed to a life of signal degradation? I would prefer to leave the Y path enabled and just use the volume pedal in my loop to control my XXX.

Ah - I think I know how he's doing it. That method works fine for AB pedals, but as he says in Y mode you get a ground loop again. There are two ways to "properly" isolate an ABY; either you use a transformer (like mine and the Lehle units) or you can do something clever with op-amps, which is cheaper but I've not tried it.

 

If you want a permanent Y then I could do you a ground isolation box for
