Using this Fender Blues Junior IV amplifier is a breeze. First, connect your guitar to the input jack. Plug the amp into a 230V EU power source. You can use the 1 - button footswitch to control certain functions. When you're on stage or in the studio, adjust the tone controls to get the warm and versatile sound you want. Remember to place the amp on a stable surface. Keep it away from moisture and extreme temperatures. For maintenance, clean the exterior regularly with a soft cloth. Check the tubes occasionally, and if they start to wear out, replace them with the same type (3 x 12AX7 preamp tubes and 2 x EL84 power tubes). Also, make sure the speaker is free from dust and debris.
