Q: Is it bad to use a guitar with a bass amp or a bass with a guitar amp?
A: Yes, it can be bad. The most harmful combination would be using a bass guitar on a guitar amp. The bass guitar covers a much lower sound frequency than a guitar and therefore requires a bigger speaker. Playing a bass guitar on a guitar amp that has 8", 10", or even 12" speakers can damage the speaker.
Although it may not have as much risk of damage, a guitar played through a bass amp that has 15" or 18" speakers would not get the proper tone needed for a great guitar sound. Guitar is a midrange instrument and is best reproduced with a 10" or 12" speaker.
I strongly suggest that you get the proper amp for your instrument to ensure great sound and no damage to the amp.
