You plug into your headphone jack on the computer with a cable that has one jack on each side then plug the other jack into a 1/4 jack adapter & 3.5 mm then plug your guitar cable into the adapter and the other side into your amp

I plugged in my headphones, but it didn't eliminate speaker sound. What am I doing wrong? Thanks

Assuming you plugged into the headphone jack, the switch contacts on the jack have apparently failed.

A cheating way to disable the speaker is to plug in a plug that has no connection to the terminals into the external speaker jack.

My CD/MP3 in jack is pushed inside the cover plate

Open the amp and INSPECT the jack. It may require replacing OR simply need to have the pins re-soldered.

These jacks used on guitar amps for the most part are JUNK and easily damaged.

Hint: Loop guitar cables through the handles before plugging in or use a right angle adapter to avoid accidents that bend the plug sideways and BREAK the internal jack in the amp.

Epiphone BB King Lucille guitar treble pickup in mono mode

Realize that when you plug into the one jack it disconnects the fingerboard pickup from the mix.

DO NOT USE "stereo" cables as it is intended to use TWO MONO cables, one for each side of the stereo.

IF you plug into the one jack that will connect to the bridge pickup, it will disconnect the fingerboard pickup from the mix BUT leave the fingerboard on its own jack.
That same jack will have BOTH fingerboard and bridge pickups IF the second jack (bridge) is not plugged into.

This is according to the schematic. If you find that yours works backwards, then either the schematic is wrong OR your guitar pickups may be electrically swapped.

I own an akai XR20 drum machine. Was using it and the thing froze. The toggle still changes the bpm but nothing else works, and the (a) button is not flashing, though all else is lit. please help!

If you were in Record mode and forgot to press stop it will loop continuously until you do.Try holding Pattern/Song and press Play to see if it will play the demo song. What does the display LCD say? Are you stuck in System Setup mode?Are you stuck in Record Setup mode? If the record button is not flashing you are not in Record mode.Have a look at page 15 in the manual and see if it will go into Pattern mode. I forgot to ask you if you have a manual. If not you can download one here: The reason I asked you about the footswitch is that when you power up the XR20 checks the footswitch jack to see what kind of footswitch you are using. The manual unfortunately doesn't mention what would happen if the jack failed. This can happen sometimes when a cord plugged into a jack gets kicked. The solder joint between the circuit board and the jack fails rendering the jack non functional. I also didn't ask you if you are using batteries or the correct power supply. Try describing to me what the display says. Let me know if any of this helped.

BR 8 headphone jack

This may also sound stupid but; have you tried a different set of headphones? If you have never used the headphone jack there might be a chance that the contacts inside the jack are dirty from airborn pollutants such as cigarette smoke or cooking smoke. Another good example is if you have a flute or silverware laying around in the open , they will tarnish from the sulfur dioxide in the air. Try spraying a very small squirt of contact cleaner on a stereo plug and plugging and unplugging it into the jack. Make sure you do this with the power turned off. If that doesn't work, do it to the jack itself. Only use a very small amount. If that doesn't work you may have a bad solder joint in the connections to the jack or a circuitry problem. The jacks sometimes a have a built in switching circuit to defeat the signal when phones are plugged in and sometimes the jack fails. Hope this gives you some ideas.

No sound unless a plug is partially inserted into the effects loop jack.

The switch that is a part of the effects loop jack is making poor contact.

Open the unit and ALSO check the soldering of the jack pins.

MANY of these have a contact as part of the strip that contacts the plug. This spring strip often gets weakened and doesn't contact the metal contact below. The contact "forwards" the preamp to the power amplifier. If the contact doesn't quite make, no power will get to the power amp. If the jack is bad, you MIGHT also try a jumper plug. You MIGHT be able to bend the contact to get moore force as a repair.

If it is a mono 1/4 jack, then use a short jumper from the FX send to the return is another non-invasive fix..

IF it is a TRS type effects loop, plug in a plug that has the Tip and the Ring jumpered in the plug as a quick fix.

In general the jacks in these guitar amps are JUNK !!!

The guitar lead plug has fallen inside.

The safest way to fix this is to take the amp apart to get at the jack. If the jack is a solid black plastic shape, then you should replace the jack completely. Otherwise you should have access from the side of the jack to remove the piece of hte plug that broke off.

Getting Static noise when plugged in to amp

This is a very common problem that I have repaired for many friends. Sometimes the guitar jack becomes loose and gets rotated to the point where the wire breaks and/or touches the cord plug when it's inserted into the jack. You need to remove the access plate/panel at the back of the guitar body and see if the wire is broke or twisted. You may only have to loosen the jack retaining nut and rotate the jack to get the twist out or you may have to remove the jack and resolder the wire back in place. If its broke make sure to solder back on the proper terminal--the one with solder already on it and not the one that the cord plug touches when its inserted. Retighten the jack nut by firmly holding the jack from access side so it doesn't rotate again and cause that undesirable STATIC sound. Hope this helps.
