I know the going rate for 2x12" Maverick combo is about $750 in decent condition. If I recall member claimed he got his for $550 (I'm guessing ... or was it $450 which is a steal).
So for a head and 1-12", I'm guessing $600 to $700 depending on condition. Now this is if you are in the US. In foreign countries, Boogies in general is like at least 125% or more than US prices.
example: Here a mini-Recto is $999 and I think in England its $1795!
I seen in Craiglist someone locally (Bay Area) wanted $1295 for a 1-12" Maverick combo claiming its early MESA prototype. Maybe a collector would be interested but that's too much for us lookers (lol).
Are you selling or buying?
