Hi Mark:
I have a Melody "Grabber" - I bought it new in the early '80's and it's just going through an electronics restoration now (new pots and rewiring) as well a general clean-up since it's been sitting in my studio in the USA for 30 odd years! It is in pretty decent shape though with just some dings, notably on the bottom bout. I do plan to bring it back to the UK later this year, so if you are interested, drop me a note. Dave.
