Your general opinion of this product.
Excellent preamp to use in your electrified aocustic sound chain. two inputs - selectable with a switch or blendable, and with separate switchable piezo boosters if your guitar does not have a built-in preamp.
Dedicated tuner out (don't have to worry about a noisy tuner in line); built-in boost to jack up your volume for leads, switch also controls an FX loop. XLR balanced and 1/4" (amp) outputs. Notch filter to take out the bad feedback frequency. Semi-parametric EQ.
