Please read the following, although it's a bit long. This is the official guitar controller for Konaste GITADORA. I am selling it because I haven't been playing it at home as much. Purchased in June 2022. This unit has been modified to arcade specifications after receiving the neck button replacement for the initial lot. Modifications and Feel: * Adhesive lead sheets were applied inside the neck and body, increasing the weight from the default 1.4 kg to approximately 2.5 kg, which is close to the arcade feel. It feels quite similar to the arcade version. * Neck button springs removed (I was told by the staff at the home that they were removed, so I removed them, but the feel is still slightly more distinct than those in well-used game centers. It's closer to the Arena model. The original springs are also included.) * The pick springs were replaced from the default to the push spring C199 standard. (Initially, it was too heavy, so I changed it to C181 -> it became too light because the stickiness was completely gone, so I changed it to C199. It's a little heavier than the well-used cabinets. The original springs and C181 standard springs are also included.) * To address the metallic sound during picking and the feeling that the stroke was a bit deep, I adjusted it with masking tape. The sound that was bothering my ears has been significantly reduced. Product Condition: Regarding scratches, etc.: * The initial screws were quite tight, and when I turned them for the first time, a crack like the one in the photo appeared on the pick cover. The screws themselves are structured to go into the metal inside, so there is no cracking or spreading, but please be aware of this if you are concerned. * There are circular marks from the wrench rotation on the back, which occurred when opening the unit. * There are noticeable scratches near the USB port, as shown in the photo. Otherwise, the condition is generally clean. Playability: There have been no malfunctions such as dropped notes or stuck notes, and I have cleaned the inside and reapplied grease during the shooting this time. The lead has not deteriorated or peeled off and is integrated, so please rest assured. I highly recommend it in terms of playability, as it is very close to the arcade version. Accessories and Shipping: All accessories are included: the guitar strap (shoulder belt), USB cable, and instruction manual. The strap has been cleaned. The springs before modification and the springs that were not used are also included. * Please note that the stand, grease, silicone, and other items shown in the photos, as well as purchase bonuses, are not included. Shipping will be done in the manufacturer's original box used for the initial delivery.
