Guitar Effect Bypass
How do you troubleshoot a broken guitar pedal?
There appeared to be only one burnt out component and I replaced it but it still doesn’t work. it was the D1 diode that I replaced. It was broken (had burst) and there’s also a burn mark on the perf board. A near by wire was also singed but I replaced that. It did look like something was spilled inside the pedal and I’ve cleaned that out. When in bypass, the signal passing through is distorted and garbled, like hearing it on a faint radio station. But when the pedal is engaged, it doesn’t pass signal at all. I’m pretty certain that this is a copy of the Boss TR-2 because the schematic seems to fit with the exception of the IC chips.

Since the “bypass/engage mode” is triggered by a momentary switch, and the dry signal goes down a very processed chain of components, I haven’t been able to figure it out. What typically goes bad when there are spills? How would I go about figuring out where in the bad components are?
fix it?

How to fix the delayed sound produced when using Guitar Rig 3 software ?
How to fix the delayed sound when using Guitar Rig 3 software (sound produced is not synchronizing with the strumming) ???
i’ve properly plugged the guitar into the computer’s microphone input. it produces sound on the computer, but it is delayed at about 1 second…
thus when i play a song, the sound is not properly synchronizing with my strumming though i play it really right when i’m not using that software.
also the “delayed effects, reverb, etc” was disabled on Guitar Rig software, however it outputs delayed sound from the guitar…
i’ve tried to bypass or turn off the effects, and still it was also delayed. 
Does anyone out there knows how to fix that prob ????
i don’t have the Guitar Rig 3 Kontrol Foot Controller, btw, so how to fix that without this foot pedal controller…
Please post your answers here if you really know how to fix that…. thanks so much and keep rockin! 
This is called Latency — it is the time required for you interface to digitize the sound, buffer it, the computer to read the buffer, process it, write the results back to the buffer, the interface to read the buffer, and finally to convert it back to analog for you to hear it. Look up the manuals of GuitarRig and your audio interface for instructions.
You can never completely eliminate latency, but you can bring it down to livable times.
To adjust latency, you need to choose a good quality driver for the sound interface, then change the buffer size. It is also dependent on having a good quality audio interface card. If you are using onboard audio or a basic Soundblaster card, you’ll have fewer options.
First of all, go into the Audio settings or Preferences of the software, and choose the ASIO driver for your interface (not the WDM or other driver)
Make sure your audio software and interface drivers are up to date. If your sound interface did not come with an ASIO driver, try asio4all http://www.asio4all.com/
Then change the buffer size. It is expressed in bytes, you probably have it set to 1024 or more. Reduce this to 128 or less. You’re shooting for a latency of 20 ms. or less, which should be tolerable as a lag time to your playing.
The trade off us that when you reduce the buffer, you reduce latency (because it takes less time to fill the buffer) but you increase the chance that your computer processor won’t be able to keep up, and you may get audible glitching in your audio. You need to strike a balance between audio consistency and latency. You can try reducing the amount of things you are asking the computer to do at the same time — turn off all unneeded programs, use only the minimum EQ, compression and effects software while recording (you can add them later in processing the track or mixing), minimize the number of audio tracks you have playing as you are recording.
If you have selectable bit rates and bit depth for recording, then reducing the rate and depth will reduce latency problems. 16 bit / 44.1 KHz sampling is way easier for the computer to process than 24 / 96, so you can reduce the buffer size.
The other thing you can do is to reduce the buffer size for recording live, and the increase the buffer again for when you are mixing or working ‘inside the box’
Lastly, if you are relying on the computer to supply the effects, distortion, compression and EQ on your guitar sound, consider using outboard hardware effects to create the sound before recording it. You will lose some flexibility in modifying the sound later, but the load on the computer will be lessened greatly. Look at amp simulation and effects boxes from Line6, Johnson, Boss, Digitech, Korg and others. A bonus to this is that you can monitor the analog signal while you are playing, with no latency. If your track ends up out of time with the computer tracks, no problem, you can shift it forward or back on the timeline, or apply the software’s latency compensation features to line it up again.
