I'm looking for a little advice from those of you ladies and gentlemen who are more tech-savvy than me-- which would probably be most of you! I have a little Kustom 4-channel powered mixer, paired with some decent speakers, and I'd like to try just plugging my Tele directly into it for a coffeehouse-type gig that I have next week, rather than using a free-standing amp for the Tele. As I recall, the signal that was produced when I tried this once several years ago, although not horrible, was pretty weak. Is there a not-too-costly device out there that I could run my Tele into first, and THEN into the powered mixer, so as to make the Tele sound fuller and punchier coming thru the PA speakers? By the way, the other 3 channels would be occupied by my buddy's acoustic guitar, and each of our two microphones. THANKS!
