The MXR Micro Amp has been a staple among the world’s top artists because of its ability to boost and sweeten up your guitar or bass tone and drive the front of your amp. The Micro Amp+ builds on that classic pedal with EQ controls and other upgrades that take this powerful boost box to the next level. With its Gain knob, the Micro Amp+ allows you to dial up just as much gain as the original - up to +26dB - but with added EQ controls, you can now finely sculpt your boosted signal. • MFSKU M233 • UPC 710137095274
