This is my DIY try build guitar amplifier using LM3886 gainclone IC.

I design this project with some feature like Clean/Drive switch option, Time/Delay effect like echo that can costumize, and also tone controll : Bass, Mid, Treble, and Volume.

I add an aux input so you can use for practice with sample music from your phone/mp3.

It also have headphone out but you need to costumize the R34, R35 to make it work with your headphone impedance

By the way this guitar amplifier can give power about 50-68W according to your speaker impedance and your transformer. Here for test I use 24V-0-24V /10Ampere transformer, but you can use about 3-5A transformer.

So, what does it sounds like? please check the video on Barlex Respectaizer Youtube channel
