I'm new to the MFX game, so I need some unbiased input. I want an MFX unit which: 1) can live happily either direct to a PA/mixer or in front of an amp, 2) can be used in a preset or stomp box mode and 3) has rich, realistic sounding od/distortion and timed effects. The older DigiTech RP1000 and the new Zoom G5 can both be had for $300 NEW, so which offers the better value? Being an avid hobbyist, I'd like to hold my expenditure to $300 or less, so are there any other worthy options to consider? Thanks so much!
