Portable Guitar Amplifier - DIY
Welcome To "Sam Technology Professionals" Hi Guys..!! This is a portable guitar amplifier with some exclusive function. It gives you clean sound, bright & loud sound and distortion guitar sound. Even if you connect a semi acoustic guitar it will work as it do. It is good for high impedance pickups and microphones as well. ________________________________________ Details : It is based on two IC "LM386" and some capacitors and resistors. It works fine...
