Slowing becoming un-noob.
Alright. So this is another curiosity question...As in, I'm not going to do this for a great long while.

Would there be a way I could get another SCXD(I already have one) and use both them...Use them as in, use one for one voice, and use the other for another voice?
Yeah, waste of space. But is this an easy thing to do?
Just curious.
Thanks.

Reason for asking this if you're wondering:
I found I love the clean on voice 1. Can't get enough of it.
I also use distortion a fair bit as well. I sure can't switch instantly between the two due to them both being on the same channel. So there is my dilemma. I still like the channel 1 clean, so I can deal with that just fine.
 
A/B box (between your guitar and the two amps) -- doubles the fun :) I don't have many effects, but I've got two of these
 
el, Voicing #4 on Ch. 2 of SCXD seems to be about the same as the clean channel 1. Try that.

otherwise, yes, you could have 2 and a/b with a footswitch.

I have a channel footswitch and I'm quite happy with my 1 SCXD, although in a perfect world i'd like both channels to have all the different voicings, cuz maybe i want some different cleans :rolleyes:

Um, as far as the #4 being the same as clean channel 1. That would still have the same problem. Maybe I worded my first post wrong. But both effects I want to use are on channel 2. Voices #1 (clean), and #3 (distortion).

I have the footswitch as well, which is why I won't buy another SCXD for a while, I can live just fine with channel 1 clean.

But that A/B footswitch thing sure seems promising.

Thanks for the info guys.

oh, I see: you want to use 2 different voicings from Channel 2 (modeling), one as your clean, the other as your "crunch". Me too :D

it would've been so easy for Fender to make both channels identically versatile (modeling). but oh, well.

Yeah. Oh well...

wait...

Are there any mods that are able to make that happen? Or is that just WAY too complicated?

i haven't seen any. among other things you'd need a "drive" knob added. i really don't think so.

what you COULD do is the "line in" mod and then use a modeling preamp (like pod or vamp). That's like turning your SCXD into a "power engine" - just the Class A/B power section.

MODS like that VOID WARRANTY!

Yeah, I've heard of that one, but I don't feel like buying anything more. I love the sounds that are in the amp, so yeah.
And yeah, I know the warranty deal too, screw that.
 
A/B box will do the trick, make sure you get a good one, i bought an ART and when A/Bing there is bleed from one to the other- faint but still not a true bypass of the other signal.

Oh, alright, will do. Like I've mentioned, I won't be getting a new amp for a long time.
 
New Question

So lets say I do this whole 2 amp deal.
The question is now...
[size=+3]Would I be able to use both of the speakers at all times? somehow hook them up, so whatever amp I was switched to, I could be hooked up to both speakers?[/size]

No...not without mods that would make the above mentioned mods seem like mere child's play.

Really?
Dang. I figured there would be some combination of daisy chaining that would work, like a 2-1 splitter that is like... I'll try and make a little diagram.

Amp #1-->SPLI-->speaker of amp #1-->(daisy chained)-->speaker of amp #2
Amp #2-->TTER

Something like that wouldn't work?

An A/B box will only activate 1 amp at a time-if I understand what you want I think a 'Y' cable with a mono send and 2 mono outputs is what you are looking for. It will look similar to the picture below, and would be easy to build with 3-1/4" phone plugs and some shielded guitar cabling. This will let you use 2 amps together all the time.

I've got two A/B boxes, and actually, they're both A or B or A+B -- one is a whirlwind, and it works great. The other works fine, too, but I can't remember what brand it is. The A+B sends the signal out to both amps - obviously, there's a battery involved that keeps the signal strong in both directions.

Did you say you want to wire both speakers to each amp? That's kind of spooky sounding, and I'm not sure how you'd make it work. Also, you should experiment with speaker loads, because if you mess up, you can damage an amp (or two :D).
 
Alright, so here is a rough diagram of what I was thinking.

I diagrammed it with the speakers outside of the amps to make it more clear. Just think of the speakers as separate cabs, and the SCXD's don't have speakers.

Would this work?

apparently not, because you're basically trying to drive the two 8-ohm speakers with 1 power amp (which has a 8-16 ohm power out).

From what I understand, if you run the 2 speakers together (I wanted to do that too) you'll end up with a 16 ohm load, which will defeat the purpose of having 2 speakers (if I understand that correctly). Plus, you'll still need to do some soldering to even make that possible.

You'll also need to do some soldering to add a line-in on the driving amp, to run the other amp's line-out.

way too complicated and voids warranty on both amps.

you'd be better off getting an external cab, like the currently cheap Crate V-series 2x12 ($120 shipped!). Then you could maybe mod to add a line-in and get something like a modeling preamp, maybe a SansAmp, which would model a similar clean you want. Standard SansAmp GT2 has a "Fender" rig, but they also have their "character series" Bassman sansamp. Or maybe the Boss Bassman pedal?

Keep in mind, in your drawing you're basically using SCXD's digital preamp on one of them and using the power section of the other (with or without its preamp) to drive the 2 speakers.

With that kind of investment, why not just get a decent fender 2-channel all-tube amp, like maybe Hot Rod Deluxe?

I'm so confused by this.
I don't want to sound too much like a jackass here, so just so you know, I really do appreciate the input, and I'm really trying to understand:D

Alright. So the 2 speaker thing. They would be daisy chained. As if they were separate cabs. I've been told by members on this forum that when you daisy chain speakers it doesn't affect anything. But this is just what I remember, I might remember wrong, or have been told wrong. So I just want that to be clear.

when you say this...
"Keep in mind, in your drawing you're basically using SCXD's digital preamp on one of them and using the power section of the other (with or without its preamp) to drive the 2 speakers."
I don't get it.
Why? In my drawing I (this is at least what I thought...) I have it so the guitar will only be going through one amp at a time, and that the amps aren't connected to eachother in any way. Only one of them would be played at a time. And then only one of them would be powering the speakers at one time.
Does that make sense? I don't get the whole using digital of one and power section of other. If you could explain, that'd be sweet :D

Soldering I don't mind really at all. I'm just wondering in theory if something like my diagram up there would work.
Assuming I'd be using just the "amp" part of the SCXD's and that I'd just use 2 separate cabs.(both have in AND out on them for daisy chaining).


So does that make more sense? Did my diagram just not make sense? Or does everything you said still apply here?

Thanks again for the input. This stuff confused the hell out of me.

First off, it sure looks to me like in your diagram, assuming each of the two speakers is an 8 ohm speaker, you are looking at a 4 ohm load. For the 8 ohm output this is not a good idea and will add a lot of stress to your amp. It may handle it for quite some time, but it may not last long either before you are replacing an output transformer. What would worry me about this layout is that you have two amps hooked to one set of speakers. This could be an issue, but I am not sure how it will affect things because I think it depends partly upon other factors that are unknown to me. One thing I would at least be wary of in this situation is getting a GOOD A/B pedal that does not allow you to do a Y signal path like many A/B boxes do. If you were to accidentally hit a Y setting, both power amp sections would be feeding the same set of speakers at the same time. Technaically this may or may not be a problem, but it seems like there are some bad possibilities there.

If I am reading properly, you want to be able to use two settings on the same channel that are not accesible in a usbale and proficient manor. As a result, you want to add a second amp so you can just leave each one in its proper setting and instead switching presets, you just want to switch amps for each different sound. This is pretty standard practice and where an A/B or an A/B/Y pedal is pretty common and useful. Where it gets tricky is that you want to use the speakers form both combos simultaneously, but from the power amp section of whichever combo you are currently switched into. This is a bit more of a serious problem. Your solution may work, but like I mentioned before, I see some problems that might exist. Mostly the two power amps referencing the same set of speakers. In and of itself, this should be fine, if you run your speakers in series instead to change the overall impedence load to 16 ohms, but if both amps were to somehow kick in at once, I am not sure what would happen. If you could live with the sound of one amp driving its own speaker and the other driving its own, an A/B/Y pedal would be a fairly cheap in very useful solution, but it means you have to mic each combo up, and that each one gets only 1 speaker instead of 2 which changes the overall perceived output by quite a bit.

Also, if you are getting an A/B or A/B/Y pedal, I would seriously consider looking at the Radial pedals. They cost a little more than other brands might, but are also built much better.
 
Really?
Dang. I figured there would be some combination of daisy chaining that would work, like a 2-1 splitter that is like... I'll try and make a little diagram.

Amp #2-->TTER

Something like that wouldn't work?

Actually, you can. Radial Tonebone makes an amp switcher to switch between 2 amps to the same cab. You can wire up the two speakers together (As if they were together in one cabinet), and hook up the outs of the amp to the switcher, and the switcher to your "cabinet". Be aware, wiring the speakers together will change your ohmage. Doubled in series, cut in half in parallel. This will only work if the amp can be outputted to a different ohmage than the built in speaker by itself.

This also incorporates an A/B. It's pricy, though.
