I show how to repair the input jack for a Roland Micro Cube Guitar amplifier for less than $20. A common problem with this type of amplifier, is that the input jack is easy to crack. Also, the plastic nut that holds it in place, can easily loosen, which can cause damage when plugging your guitar chord in. After repeated use after 6 years, I cracked the input jack and could no longer use the amp. I decided to try and repair it myself, instead of buying a new one. I called Roland, described the parts I needed and they sent me new ones. The jack and nut cost around $5 each plus shipping. It took about 5 days for the parts to arrive after ordering. Here are the part numbers: (Note: A viewer reported that Roland will no longer sell the parts anymore. Please provide your experience in the comments below)

Jack Nut - #22150756
