Please read the following description and profile before purchasing or commenting. [Manufacturer] MXR [Product Name] M80 bass d.i+ [Condition] Junk [Accessories] None (body only) ・Operation confirmed with both adapter and 9V battery. ・Confirmed that all knobs and footswitch are working. (Ground lift switch operation not confirmed due to lack of testing environment) ・Output confirmed from all outputs: output, parallel out, and cannon out. [Reason for being junk] ・The 9V battery cover is missing. ・The nut on the parallel out jack is missing. ・The volume is low. →The volume decreases when connected compared to direct input. The volume decreases further when the effect is turned on. This phenomenon occurs with the output jack and cannon out. The parallel out seems to have the same volume as direct input. Please refer to image 11. I have roughly measured the volume level in a DAW. All external factors such as DAW and I/F settings are the same, and the volume is measured when the E string of the bass is played. ① is the volume of direct input without connecting this product. ② is the volume of the through sound with this product connected and the effect off. ③ is the volume with the effect on and the volume knob at the 12 o'clock position. ④ is the volume with the effect on and the volume knob at full. Based on the above, this is being sold as junk. The color, distortion, and preamp are working correctly, so it might be usable if you use a booster to increase the volume and keep it on at full volume... but I don't recommend it. Please purchase with the assumption that repair or parts replacement will be necessary. Velcro is attached to the four corners of the back. This will be shipped as is. I am not considering lowering the price. Shipped via Yu-Yu Mercari.
