How do you make an amp cover?


Sometimes, we purchase a second-hand amplifier with no cover, and we want to protect that from harmful substances. Or, sometimes, the cover we bought years ago is starting to lose its charm. In this situation, we have created this guide for you to make your own amp cover. 

Here you go!

What are the first and second steps?

First of all, take measurements of your amp carefully. It all depends on the measurement, so you would not like to mess it up or ruin your efforts for nothing. Careful measurement is essential to move forward.

Secondly, buy a cloth or even canvas of your choice. The color and yards of the cloth depend on your choice and measurement of the amp respectively. You can buy any color you want. (We suggest buying a dark color since it does not get dirty easily). Now, for the inner liner, you might need to get a sheet with no elasticity, a cotton batting, and a bias binding tape for finishing off the bottom sides along with the hole of the handle.

What do I need to do after that?

Now, after taking the measurements, you need to make the top, front, and back of the cover as a whole piece. To do this, measure every side of your amp, and then add all the measurements together. 

So then, you will have three main pieces, one big piece, and two side pieces for the front, top, and back. After that, add ¾ inches seam allowance throughout the sides over and beyond the large piece. Then, carefully cut out the inside sheet (fabric). Now, cut the canvas for matching, and lastly, cut the cotton batting in the same size.

How do I sew them together?

Further, pin these three pieces together and quilt them with a horizontal straight line sewing 1.5 inches away from each other using the same color thread as the color of your fabric. For this, you need to have a sturdy sewing machine to sew and quilt, so it can work great with thick layers as well.

Your next step would be making the holes of the handles in the middle of the top. First, sew a straight line on all sides of the big piece for marking exactly where the top is and do your measurements using those lines in view of precision.

How do I define my cover?

To make lines on the cloth, use chalk to quilt to define the top part of the cover. Now, if you want any kind of barrier for protection on the inside back and front of the cover. Here is what you should do. Avoid using cardboard for this purpose because it might get soggy or moist if it touches the water. 

We suggest using a quilting template because it remains in place and it doesn’t get moist. Hence, you need to purchase some big enough quilting templates to fit the measurements of the back and front of the amp. You can try to find it in your local market and you can easily get it online. However, you would need a thicker base. After purchasing the quilting template, you need to cut every piece of it to fit.

Moreover, before starting to sew the sides on, cut 2 pockets for sliding the plastic into. In order to do this, use the measurements for the back as well as front but simply go up about ⅔ of the total height of the piece, then finish the top of every pocket piece (roll ¼ inches down at least two times and then stitch) and pin all pockets into their places on the inside of the large quilted piece. This will make your plastic removable, so the cover will be easy to wash as well.

For additional pockets on the cover

If you want a pocket on one or two sides of the amp cover for carrying the amp cables in. What you have to do is cut a piece of the inner fabric and then cut the canvas for matching the inches. Now, stitch them together round. Now, carefully trim the corners, and then turn them right side out and tuck in the open or unseen parts. Pin it on and sew it at least two times for sturdiness. For extra strength of the cover, you can also do some additional sewing along the top of every side of the cover.

In addition to it, pin one side on its place, taking the wrong sides out. For doing this, match the top corners of the sides with the straight lines you had sewn in for marking the top, pin each one of them. Then, pin the sides as well and match the bottoms. Now, stitch the side pieces in their places, pivot, and ease at the corners carefully, so you don’t get puckers. You might want to stitch that again for strengthening the seams. Now, make sure to clip the corners. Follow this process for the second side as well.

The last step to make it look even better

Now, at this point, trim down the seams within ¼ inches and use double bias binding tape and sew it on the seams. So the cotton batting will not get frizzy on the amp and it will look great too.

Now, trim the bottom for making it even and sew the double bias binding tape for finishing the bottom. To get rid of the chalk lines, wash the cloth in your washing machine and let it dry under the sunlight. If you want, you can cut every plastic piece to fit and tuck them inside every front and back pocket.
