1 Kevin Frye 9 months ago My friend whose thrifty nature has led him to purchase an entry-level Behringer acoustic amp has presented me with a conundrum that I seem unable to answer- at least, not the answer he wants to hear, at any rate. He picked up an AT108, which has one XLR (mic) and one guitar input, bass, mid and treble tones a 1/4in "CD input" (?). It's important to note that this model is utterly devoid of any sort of auxiliary input-output jacks, which is the problem.Being Behringer, the amp is Gobi-desert dry, utterly devoid of any presence a problem easily fixable in my world by added a pedal or pedals to the guitar side, but not so easy when the user ALSO wants to add some presence to the vocal side of the equation, so here is his question."Is there an effects pedal that would provide a "two in, two out" configuration that would allow one to add the same effect (reverb in this case) at slightly differing levels to both channels on the Behringer?"My feeling, which I did tell him, is that it may indeed be possible, though I haven't yet seen one, but the investment in such a device would likely be well in excess of his investment in the little amp.Am I right?
