In a guitar, the mic feds back horribly at even modest volumes, and no amount of positioning can correct this. The sound is terrible, like a really cheap tuny mic. I would only recommend this in situations where there is absolutely no other solution.
A lot of bass and dark sounding. Doesn’t go well with the tone zone I have in the bridge. Not great for classic rock . I did my research and took a chance but you never know until you get a pickup in your guitar with your amp.
