MXR M133 Micro Amp Gain / Boost Effect Pedal

Take Control of Your Guitar Rig's Gain Levels!

The MXR Micro Amp level booster pedal lets you take control of your volume level before your signal goes to the amp! Boost your signal for leads and switch it on when you need it. Use the Micro Amp to match the output levels of your humbucker-equipped guitar and your single-coil axe. Push your tube amp into that golden tone zone. If you use several pedals, this handy unit lets you bring your signal back up to the level you need before it goes to the amp. Give your rig a boost — use the Micro Amp!
