Got my Martamp 2 x 12 cab for sale. It's an amazing cab!
The speakers are 2 25w Celestion Greenbacks but with cream backing. I think they were made in 1974, but I may be off by a year or two. White tolex, gold piping and black and white checked grill cloth. It's also a ported cab but the projection it has is great.
The speakers alone are worth over £100 each but I'm only going to ask for £200. You can collect it or I can deliver if you live about 45 minutes from Hatfield.
I don't have a picture yet but I'll upload one later today.
