Watch the 'blend control on this preamp
I have 2 of these Berhinger Preamps and they are terrific for pickups without preamps - BUT BEWARE - the "BLEND" knob is a let down. Its supposed to blend in a modeling function but after about 10 minutes of use, with the blend at 1/2 to full - it clips in quite an ugly way. I use this for non-preamped pickups like K&K in my octave mandolin. Sound is good, strong EQ function - but leave the blend off.
