i have a 100.4 in exceptional cosmetic condition but it has been used for around 7 months. purchased in dec last year, didnt install till i had all my gear which was around late febuary. id give it 9.5 of 10 cosmetically and 10 of 10 functionally, i have a brand new remote gain knob to use if u wanted to wire a sub to 2 channels bridged.
it has a little over a year left on warrenty, never had any problems with it at all.
Also have a sax 100.2 literally lnib. and a bnib us amps 05 - 06 model merlin md22 that was taken out two days ago to test out for making sure it wasnt a doa.
