Install the Effects loop.

Unplug the internal speaker, run a 1/4" from the Effects out to a power amp. Tube or solid state, although you might prefer the sound from a tube power amp.

Plug cabinet into the power amp.

I'm using my VIP-1 (the one in the pictures above) as a preamp myself. :D
Just curious, what are you playing it through?

You could wire these speakers in series for 16 ohms :idea: http://www.google.com/url?sa=t&rct=j&q= ... tNi-ERlXpQ
You probably wouldn't want to go higher than 16ohms, but it would work. Which vypyr do you have?
VIP 2. Is it safe with solid states to run 2 speakers in 16ohms since the VIP2 is only an 8 ohm amplifier?

I think it would be wise to read up on this a little. I haven't done this myself so not ready to say absolutely yes on this one. From what I have read it seems like the answer is yes, but you will probably suffer a little volume loss for the extra load. This might be a good topic for another thread where traffic outside of the effects loop mod can see it and maybe someone out there has done this very thing.

Effects out into the computer, then I run a power amp plugin (Ignite's freeware TPA-1 is a good one, and Revalver comes with a bunch) and speaker cabinet IR.

I've seen used ones in the $100 price range. Lots of leftover rack stuff from the 90s is out there. :)

They should be wired at 16ohms, at 4ohms the solid state amp will fry is the word. Tubes on the other hand handle things differently. Is there a chance I can make a speaker out mod from anything on this board?

Yes. I did a search on this forum and indeed this is a topic that has been talked about and done. Not sure if any post include pics or not. I did find this rather quickly by searching the google. It seems to be a pretty easy, cut and dry mod. Very little surgery. Using the speaker wires connect them to a 1/4" female jack. make a cable with 1/4" male end and crimp on spade connecters on the other for using with the vypyrs own speaker. When you want to drive an external cab just use a guitar or speaker cable and you are done :mrgreen: http://www.agileguitarforum.com/showthr ... ?tid=14377

Thanks for the compliment, but God's works is really much harder. I mean people die doing that stuff! :o I like my vypyr, but I don't think I am willing to die for it. :lol:

So FYI, I had been experiencing some radio frequency coming through my amp. Very faint, almost airplane like up and down sine wave. One day it was loud enough to hear some voices coming through. It wasn't real loud and couldn't notice it while playing guitar. Just loud enough to be annoying when guitar was at rest. Anyway. I figured it had to do with the un-shielded effects loop components. I found some ferrite that came out of an old printer and made a one pass loop through it with the effect loop wires that connect to the board. For now, this seems to have totally cured the problem. I was very happy. Anyone doing this mod may want to consider doing the same to save a little potential heart ache down the road :mrgreen:

Hi, I felt really brave and try this mod, but couldnt make the modified tip for the iron pencil, so lets start from the pulled traced wire of the board ... after trying hardly to solve it decided (fortunately) to take it to a technician to get the wire to connect it to the potenciometers, the day I collect the board couldnt assemby there, so I'm proving again at home, but its acting just like I left it last week, it has signal, but its hard to hear even at max volume, after the technician I think the sound is just a little louder, but not enough to play over a song :( I've check the wiring change the potenciometers, looked after false contacts, again and again and again ... also have tried the aux input and it works fine with the volume, so I think its a matter on the pre amp section. Does anybody have any input, before I take it to the technician again? Please let me know

Thanks

Sorry to hear of your struggles here. Without seeing what you actually have it may be hard to diagnose over written communication. One thing this is reminding me of is a similar problem I had with volume when I reconnect the dsp board and powered back up with a sanpera pedal also attached to the amp. Like you were saying volume was incredibly low no matter what I did with the volume knob. As I recall it took several tries of disconnecting power and unplugging the sanpera, but finally it came back to normal. Hope this is helpful. If you have time maybe PM me with some photos of what you are working with. Especially the pots and jacks section just to be sure everything is healthy there.

Thanks for answering, I've just left the board with the tech today and couldnt take photos, but I'm confused, so you have this problem when connecting with the sampera, but how it was solved? Just by turning it on/off w/wo the pedal?

Yes, I have had a similar problem when re-installing a dsp board in a modified Vypyr 15. Things are cloudy with my memory because it has been quite a while ago. I do believe I had the problem when powering up the amp after just installing the board. This happened multiple times and I believe I had the Sanpera I pedal pluged in (modified 15 with stompboxes and midi jack). It seemed that once was able to cure the problem by cycling power after removing the sanpera. I think another time it took a few more trys of cycling power and possible even trying to reboot amp to default settings. That being said, I don't want to lead you down any wild goose chases. Logic would dictate that since you recently modified your board then we should make sure it is healthy first. In the how to pdf I mentioned using an ohm meter to test between the send and return connections. You should have no connection between them. Then you should be able to have ohm connection between one of them to one post of c79 (can't remember if send or return connection. please verify in the "how to") and the other should have ohm connection to one of the pins on u14. I personally had a board that I modified for the effect loop that looked good, but had a bad solder joint and also produced very low volume through the amp. A quick reheat of the solder joint and better connection was made and problem fixed. I would definitely check for this first.
