When you take your guitar to a pawn shop, the first thing they will do is assess the value of the instrument. They will look at factors such as the make and model of the guitar, its condition, and any special features it may have. Based on this information, they will give you a loan offer for the guitar. The amount of money you can get for pawning a guitar will vary depending on these factors, but you can typically expect to receive around 30-50% of the instrument's value in cash.
