I ordered a used guitar, and the back cover will not fit on the guitar. It is about 1/8 inch to small and falls inside the back of the guitar when you try to put it on. It is an applause series AE148 Super Shallow Cutaway Acoustic-Electric Guitar. Is there a way to order a replacement part for this?

You'll need needle nose pliers, small phillips head screwdriver, soldering iron, electronics-grade solder, socket screwdriver or 1/4" wrench, black electrical tape. Purchase necessary replacement jack. Remove plastic electronics cover plate, located on the back of the body, behind control knobs. This will expose the electronics cavity. Locate existing jack and its wire connections inside the exposed cavity. Remove any electrical tape covering the jack connections. Using a hot soldering iron, touch each of the two soldered input jack connections, one at a time, just until the soldered connection melts. Then, disconnect the associated wires (taking note of which wire connects where!). Once disconnected, loosen and remove the nut on the outer part of the jack that holds it onto the guitar body. Remove the old jack. Insert the new jack (with the nut removed) into the existing hole, from inside the electronics cavity and tighten it in place, on the outside of the guitar body, with the nut. Re-attach the wires to the new jack, by using needle nose pliers to wrap them tightly around the correct posts. Touch the hot soldering iron to each post and apply a small amount of solder to the post as it's being heated. Once the molten solder runs over the connection and looks shiny, remove the tip of the soldering gun. This process takes only 2 to 3 seconds. Let the connections cool for a few seconds. To insulate, wrap connections with black electrical tape. Replace cover plate.

If you can see the socket, get a crochet needle that fits inside the socket and pull it back up through the hole. Good luck!

Yes, Some gibson electric's have long shaft pot's, they will still fit but you will need to use another nut to adjust the pot's so they do not stick through the body to far. Knobs should fit unless the old gibson's are solid shaft. Then you will need new knobs. Many guitar parts places on net to order standard pots and even wiring kits.

You will use microphone with balanced XLR connector into the XLR mic input. Note, the ALpha does NOT have phantom power so you cannot use condenser mics.

A guitar can be plugged into the hi-z instrument 1/4 inch jack on the left front of the unit.

To use the line 1/4 inch inputs you will use BALANCED TRS 1/4 inch cables from your source.for these channels. The level on these needs to be line level.

The line outs are for sending audio out to an amp. There appears to be RCA outputs you can use as well.

I am not sure what you mean by making your "amp record"... An amp PLAYS the audio, usually into a speaker.

If you are trying to play a guitar through your amp AND record, then you will connect your guitar to the Alpha, the amp input will have a cable from say Line 1 OUTPUT and when recording wou will have the echo feature on so your guitar is passed through to the amp.

Try taking the guitar back to the store where you got it. Recreate the sound. If it is a faulty connection they will know what to do about it.

you can use the line in/mic stereo input, but you will have to turn the input level way down to around 1 or 2.

i assume that the record outputd a re rca outs. you can get a rca stereo to 1/8 inch stereo adapter, like the ones they use to connect protable cd palyers to recievers, and then get a 1/8 inch stereo to 1/4 inch stereo adapter form radio shack to complete the connection.

Have you tried another cable between amp and guitar? Usually the cable goes bad first. Have you tried another amp or possibly tried another guitar on your rig? If this still indicates that your guitar's Standard 1/4" TS Jack is noisy, remove the oval cover over the jack and check the solder joints for the wiring. Follow the wires back to the tone and volume pots and check those solder joints. If everything is secure...Plug in, power up and check for noise while turning the volume pots stop to stop. If the pots make a scratching noise, shut down rig and unplug the guitar. Get a can of spray contact cleaner with a small extension tube (available at electronic shops) to spray in the pots while turning them. (May have to remove pots fom the guitar to get at small openings on side of pot can.) Spray jack and test for noise. Jack STILL
noisy...If you can solder...unwire old jack, remove from guitar, take to electronic shop, match to Standard 1/4" TS Jack, install in guitar, resolder wire connections and test. If you cannot solder...take guitar to
a reputable shop or dealer that does this repair. Good Luck! P.S. The
spray contact cleaner can be used on the amp jack, pots and switches
too...just make sure the amp is unplugged from the power supply before
doing any spraying.

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.

Typically you have to unstring the guitar to get access to the insides.

Use a small miirror to view the insides. You may need to drag the jack out of the sound hole to resolder wires if they are broken. There should be three wires on the jack. One carries the audio, one the ground, and the third connects the battery when the instrument cable is plugged in.

After re-soldering the connections if needed, procure a piece of 1/4 inch wood dowel from your hardware store. Push the dowel through the hole where the jack goes and near the sound hole. Push the jack onto the dowel and then pull it back through the jack hole and pass the nut over the dowel and onto the jack threads and tighten. The extract the dowel rod from the jack.

It is near impossible to reach clear into the guitar body to put the jack back in without the dowel rod unless you have very tiny arms.

Guitar manufacturers use generally one of two different knob types: (1) knob has a small set screw of some type holding it on or (2) press fit onto the shaft of the tuneing pot (volume knob in your case).
Now, the problem is if it is NOT a set screw type, it is press fit. You see press fit used most of the time on lower-end instruments (and a few high end). The BEST way to get a stuck volume know off is to get a shoe string, loop part of it under the knob, brace the guitar firmly and PULL SLOWLY WITH FORCE. Realize that it is possible to damage the guitar if you **** on the string too hard.
I have never seen where a stuck know did not come off (or hear of someone breaking their guitar doing it).
I have also resorted to using a small screwdriver: work it way under the know and gently twist it to loosen it so it can be pulled off with a string or your hands.
Be carefull not to scratch your guitar!
Good luck,
