LOVE the GF-9494. It's got superb styling and features.
Really one of the 'perfectly' designed Sharps for it's time and has an excellent sound personality for music of the late 70s and early 80s.
And they're ohh so pretty!
Be aware that although being a very robust unit they nearly all have a disintergrated capstan tire that isn't hard to replace, but is necessary 9/10 times.
Also there's no traditional line-in on them. She apparently supports it via DIN plug, but I've never been able to get mine to work.
Rock On.
