Peavey Mark IV and 1820 cabinet

I bought this cab and head after listening to a local band. I replaced an Acoustic 140 head and Acoustic 2/15 cab (105?) that I regret selling (could be nostalgia). I just never got the sound I wanted out of the Mark IV. I had trouble selling it in the early 90's but that worked out well because the trades I was forced into resulted in my ownership of the bass in my avatar photo (78 MM Sabre). I replaced the Peavey Mark IV and 1810 it with a GK 400RB (deeply regret replacing that also) and a no name 15 cabinet taken in trades.
