I am trying to make a song and I have made the chorus to the song and I just want to paste the chorus two times in the song in different place. How do I do that?

I HOPE THIS IS WHAT YOU WANT

Pedals operate at a different level then rack units that go in the effects loop.
It needs to go in front of the amp input. Guitar to pedal to amp input.

You first need to deterime where the problem is, in the amp or the guitar? Plug the guitar into another amp, and then another guitar into the amp. Also try a different cord. That will isolate were your problem actually is, then we can better help you.

Always use echo and reverb, or just reverb for inexperienced singers. If I remember right this is from effect 19 but this is a very inflexible set-up with no control over the effects, just presets. You'll need to listen and decide what is best. You may also try chorus as with a decent effects unit this can be very effective plus a bit of reverb and echo.

Different songs like different effects and we will chop and change even in a single track when live mixing professional acts.

Can't find a manual but can still explain. Delays, chorus, flangers, and reverbs are all the same effect except the different names of them will allow you different adjustments. Chorus usually has a width control which controls pitch shifting. Flangers and delays will have a feedback control which simply means, how many times you hear the echo. On reverb units, room size means how long of echo(even though it;s short) you want. Delay is the same with much longer echo, feedback is the same as on flangers except the flangers time is very short meaning the effect is at almost the exact time resulting in feedback causing a metalic sound. I probaly just confused you but good digital delays usually have all the features and will usually do all 4 effects depending on how you set them. If you want delay, set width on 0 and adjust time and feedback. For flanging, adjust width and speed and feedback. Chorusing, adjust time, width, and speed. Reverb, adjust time, set width on 0, and feedback. I see it has a level(mixture, how much effect you hear), and a replay(feedback, how many times you hear it), and a delay knob,(how long the echo will be) The range/mode switch allows for settings of diferent time lengths and INF setting allows for infinite repeat. Hope this helps.

It sounds like the bypass contacts on the pedal are not working... this may be right in the pedal switch itself. With unit in off position, use an ohmmeter to check continuity between in and out cable tips.

I would check your fingering... You MAY be late in hitting a particular note and the using auto chord... this can cause the problem. Another thing is if notes are hit with different velocity that can affect the sound. Sometimes certain voices have VELOCITY switching which actually changes the voice depending on the velocity you hit a note.

Personally I recommend the following set up:

Distortion>Effects>Compression/Noisegates/Sustain

This will ensure that the signal won't have any odd hiccups due to an odd pedal setup. But if you play around with different orders, you can end up with some very interested sounds.
