Inside A Guitar Amplifier – Part. 2

By Line6Tony. If you are having trouble with your Line 6 amplifier, please check the following points before taking your amplifier to your local Authorized Service Center:. Recall a preset once the knobs are parked to ensure the tone you are working with is a preset rather than the current knob position.

Q: My master volume has almost no change past 6? A: This is due to the volume pot installed on all Line 6 amplifiers. A solution to this would be to replace it with an "audio" pot, but this modification wouldn't make it louder - just smoother. Line 6 originally installed audio pots on the AXSYS, but players didn't like them because they made the amp feel "wimpy". Players also did not like the fact that they had to turn the amp up to about before it would start "happening" and on the gig.

Even though there was still a good amount of headroom, player feedback was that they preferred the amplifier with the traditional volume pot, so that is the style used with Line 6 amplifiers.

Factory Reset Procedures. Volume and Signal Troubleshooting - turn off other volume controls not being used i. Try the amplifier with another instrument you know is functional if possible. Make sure all the input and output jacks are tight. Check the instrument with different pickup settings to make sure it is not a bad pickup connection.

Likewise, with a source feeding the input, plug the SEND into another line level device to see if you're getting signal. Tone and Rattle Troubleshooting - Check the make sure all buttons on the unit are not stuck - Be sure that all screws on the unit handle, corners, baffle boards, speakers are snug.

Q: Are the tone controls on the on a Line 6 amplifier passive or active, and where is the "flat" level? A: Each amp model is different, and the controls behaves like the target amp. Most tube amplifiers will have a passive tone stack with makeup gain. Line 6 tone stacks are designed to behave just like the modeled amp both the good and the not so good. Some amplifier tone stacks are the closest to flat when set B-0, M, T-0, but it is different for each model.

Power Troubleshooting - Ensure that there is sufficient power coming from the power outlet into the amplifier. Try a different circuit to ensure there is not a power issue at the outlet. Tube Amplifiers Troubleshooting - Make sure the tube is firmly seated in the tube socket.

Replace the 12AX7s individually and the matched 6L6 pairs to determine if a tube has failed. The digital stage and analog tube stages communicate with one another, and so are not like the all analog tube valve amps from the 's and 70's. As a result, one cannot swap tubes out like in the old days.

So please use the following specified tubes valves when the amp is taken to a service center. Presque rien ne se passe si je tourne le Master Volume passe 6, pourquoi? Ist die Tonsteuerung aktiv oder passiv?

Und wo ist die flach Einstellung? Manche Modelle sind sehr flach, wenn sie auf B, M und T eingestellt sind, dies trifft aber nicht unbedingt zu da dies auch unterschiedlich ist zwischen den verschiedenen Modellen.

Factory Authorized Warranty for Mesa Boogie & Engl

This troubleshooting page was created to help people diagnose problems with their First Act MA guitar amplifier. One factor to overheating amplifiers is dust build-up. Dust blocks ventilation often causing the amplifier to reach dangerous temperatures. The best way to remove dust and small particles is to spray the inside of the amplifier with a bottle of compressed air. Remove the back panel of the amplifier so that you can see the open wires, audio board, and other electronic parts.

Ezine Articles

In our previous article see Inside a Guitar Amplifier Part 1 , we learnt that guitar amplifiers, no matter how complex, consist of three parts. These are the preamp, a power amp and a speaker. While this basic design holds true for all guitar amplifiers since their origin, a number of key design innovations have been introduced over time. It is what the control knobs link to. The preamp receives the input signal waveform from the guitar and shapes the tone. The power amp uses the AC voltage from the mains power to convert the tiny waveform into a larger signal, capable of driving the speaker.

Bass Has Stopped Working – How To Fix It Step By Step

First, start with the basics. Check if the amp or PA you are plugged into is turned on. If using a mixer, make sure it's not muted and that all cords are plugged in all the way. Always make sure your amp is working and the cables are in good working condition. If possible, plug in another guitar to the same line to see if it works. If you don't have another guitar, plug a cable into the amp and turn the volume up slightly. Touching the end of the cable with your finger should make a loud hum noise. This tells you the amp and cable are both working.

Chris Fantana: Hi, Gareth. I sit on the preventative-maintenance side of the fence, knowing that speaker vibration, travel, and general use can cause things to come loose, components to drift in value, and wear out. It only costs a few quid and will see someone competent make sure that your amp is at least safe to plug into a mains socket. What is actually done during an amplifier service? The tech will visually inspect both the exterior and interior, examining for anything out of the ordinary.

The Musikmesse in Frankfurt was a great year for ENGL and laid the foundation for a success story that is second to none. The first programmable guitar amp was simply a sensation, something that had never existed before. Back then, when two channels and a master volume on an amp already counted as comfort features, ENGL's futuristic concept was equivalent to a landslide. Edmund Engl had the brilliant idea in the early s. He wasn't an electronics freak, but a musician.
