LM3886 guitar amp with Distortion and Time/Delay effects

By Electronic Circuit Saturday, May 21, 2022 Post a Comment

In this post, I am interested in making an amp especially for guitars.

This idea started with a request by YouTube subscriber Barlex Respectaizer who asked to make a guitar amp using the TDA7294 ic, but after I thought about it, why not just use the LM3886 ic as well so that the sound produced is better and clearer like a famous guitar speaker.

Departing from this idea, I poured it into a scheme to be made into a guitar amp product.

LM3886 guitar amp with Distortion and Time/Delay effects

As you can see in the schematic, I've added some effects to this amp, such as Clean/Drive to produce distortion, and I've also added a Time/Delay effect which is similar to echo but can be adjusted according to taste. And of course, there is also a tone control for Bass, Mid, and Treble, so that your life isn't flat, bro. :D

Then departing from the schematic above, I proceed to design the layout so that it can be printed into a PCB:

After the design feels good, the next step is I will print the PCB on PCBWay.com

By the way, PCBWay provides New Soldermask Colors - Pink, Gray, Orange, and Transparent.

Each additional choice in PCB manufacturing, means adding more customization for those of you who want to make PCBs on PCBWay, this is very important to interpret your project perfectly, especially for electronics enthusiasts and creative makers who like to show individuality.

PCBWay offers you the most options for creating unique products, such as color and material customization.

The new solder mask colors include PINK, ORANGE, GRAY, and even TRANSPARENT. What’s more, to meet some clients’ needs, we also release the “Black Core PCB” materials, so you can use them for your specific requirement. Now you can check all the available solder mask colors at the "Advanced PCB" online quote page, and we're excited to see your new boards with these new glamorous colors!
