Thank you for viewing! This is the MXR "Micro Amp (M133)," an ultra-classic booster. A favorite of many professional guitarists, it's great for clean boosting, and also recommended for use as a preamp, leaving it on all the time to add richness to your sound. 【Condition】 • Condition: Beautiful item with little signs of use. There's hardly any of the paint chipping on the corners that's common with MXR products, and it's in very clean condition. • Operation: Operation confirmed, with power and output working. The knob has no scratchiness and works well. • Back: Rubber feet are attached, with no Velcro or other attachments. • Accessories: Only the main unit is included. 【Main Features】 • Gain Control: Simple one-knob configuration. Turning it clockwise boosts up to +26dB. • Sound Quality: While preserving the original sound, it adds a pleasant thickness to the mid and low frequencies. • Durability: MXR's traditional sturdy die-cast body. 【Shipping】 It will be carefully packed with cushioning material (bubble wrap) and shipped quickly via Rakuraku Mercari delivery. These units in good condition are becoming rare. If you've been looking for one, please consider this opportunity. #MXR #microamp #M133 #microamp #booster #preamp #effector #guitar
