I'm using a Stranger Cube 20W amp + Philips Microphone (MD650 50-15000 Mhz, 600 ohm). The amp has a low impedence mic-input, and the sound isn't that bad when we jam with power vocal (heavy metal, grunge). The vocal is then pretty audible with drums+guitars going in parallel. However, if a song has whispering or close-talking or even growling, then the vocal is lost... we only hear the guitar/drums. I know I'm not using the best configuration, but that's why I'm here. What can I do to make the vocal sound reproduction come well ? Since I'm a guitarist as well, I can buy a 40W stranger amp as I need an upgrade for my guitar as well.. but buying a stage monitor should be the last option if I can somehow make-do with a stranger or kustom guitar amp. Note: Only Stranger/Kustom amps have a mic-in with low impedence, so me being a guitar player and vocalist, and have a processor I prefer buying those when compared to a Marsh/Laney amp. So, the question is, will upgradinng to a 40W stranger help ? Will some sort of processor help (lol how about my zoom 505II guitar processor ?)... We are really tight on budget, so keeep that in mind.
