Using vocal mic through bassman
Hi All,
I've been learning sonny's bird from the artist study section and decided to record myself playing with a shure SM58 vocal mic through my bassman via a lone wolf reverb pedal. It sounds great but I had to turn the volume on the amp to nearly full to get any kind of volume, which even then isn't anything like loud enough if I was to perform it this way.
Can anyone explain what I need to do to improve this?
TIA
Scorny: Maybe someone with a PhD in electrical engineering could actually explain what impedence is, but all we harp players need to know is that if the mic is rated low impedence, if going into a guitar, bass or harp amp it needs to be converted somewhere along the way to high impedence to get the "ooomph" it needs. Glad to hear the conversion is working for you. The SM58 is an industry standard (and is essentially bomb-proof), and a lot of well-known harmonica players - especially jazz chromatic players - swear by it.
The standard SM58 is a low impedence output mic. When plugged into a high impedence input on a guitar or harp amp, the power loss can be quite noticeable. Try running your XLR cable from the mic to a converter like this: https://rockinronsmusic.com/collections/impedance-transformers-adapters/..., and then plug the 1/4" plug on the converter into your Bassman. You'll probably notice quite a difference.
