Excellent condition 428 preamp for sale. This is the first version with the much desired vu meters for determining levels. This preamp sounds great on pretty much everything and has enough versatility to be modified for any type of microphone you plug into it.The unit functions 100%, but is missing the yellow cap on one of the knobs on channel one. You can see it in the pictures - doesn't affect functionality at all.Shows some cosmetic signs of use on the rack ears and some scratches on the body of the unit that can't be seen when racked.
