I am a new keyboard player and hoping to become an organ player since i always love the sounds of deep purple and Uriah heep.</p>
There is a Acetone GT-7 for sale at my local used instrument store. I cannot find alot about the gt-7 on the net. Some people seem to think it is very good.</p>
</p>
Can anybody tell me if it is worth owning, if it is fixable and the parts are available.</p>
Andy G lives in the Uk and will be awake in 5 or 6 hours from now. He knows a bit about them.</p>
If the GT7 is essentially the same as a T series Hammond, which I recall he may have said, then there's a whole stack of modification documentation available, which is a good thing. I think one of the acetones is completely solid state, one of them is a tonewheel job.</p>

Acetone was a Japanese brand that started out making rhythm boxes in 1962, adding a range of home & combo organs in the late 60's. The homeorgan models were all prefixed A, B & C with the last of them released in 1971. All had solid state divider tone generation & the B & C models incorporated a Leslie speaker.</P>
All this suggests that the GT7 is a combo product, ie. a one or two keyboard portable, no internal amp or speakers, no pedals, same technology as the home models.</P>
These products, along with the Italian Fartfizzers, really were a child of the '60''s, called "cheesy organs" by some, but very popular with bands that played the contemporary music of the day.</P>
Is it worth owning? If it provides the sound you're looking for, why not!</P>
Is it fixable? Probably, butshould it needs product specific parts you might be in a bit of strife given the age of these things.</P>
This one says Acetone was the predecessor to Roland, interesting! The pics on here show a VERY uncanny resemblance in the styling and choice of tabs etc to a T500.</P>
this onereveals it is in fact, as Ian stated, solid state tone generation:</P>
It sounds like it may have an amp board but that they sometimes have problems, but the internal amp is bypassed when you plug in a leslie. This fellow said that theother parts for the acetone are easy enough to find.</P>
Happy user reviews say its robust, has stacked contacts under the keys like a vintage hammond and is easy to repair. It sounds like it's a classic vintage instrument of its own type:</P>
Ace Tone GT7. Well, if you like the sound that the Hammond X5 makes, you'll love the GT7. The X5 was, I was told by a Hammond guy at the time, the Ace Tone GT5. If the X5 is akin to an L in its spec, the GT7 is akin to the T. It has presets on thumb pistons for rapid changes of sound without moving the hands too far. More percussions than usual. As stock, it was wired for a 147 leslie (at least it was here in the UK).</p>
Not quite the cheesy combo that Ian's thinking of, but not a tonewheel sound either. At the time, however, it was as close as you'd get, Hammond obviously thought so when relabelling the GT5!</p>
Not sure about the amp being bypassed when the leslie is used and not sure either about having multiple key contacts. I thought the organ's amp drove the leslie socket permanently and that the organ was all solid state - single contact keying.</p>
Like many clones, through a leslie it will fool a lot of people a lot of the time. Not Hammond afficianados, though.</p>

It's not what you play. It's not how you play. It's the fact that you're playing that counts.
One of these has just sold on ebay uk for over £300. Someone must think they are good. I do like the idea of more percussion that just 2nd and 3rd harmonic. Anyone ever played one? Any good?
It is to my understanding, and I could have gotten wrong info, that the same company that made this acetone made the Hammond X5. They repackaged it in a different but similar cabinet and it had a few less stops. I have an old X5 with a 760 Leslie that I haven't played in a long time. If the info I have is true then the acetone gt7 should be a fairly decent organ. The only drawback that I had with mine back in the day was that even though it was suppose to be portable, it was heavy as heck. I wouldn't pay over $500 for it ( or the equivalent to that in other currency). Another problem that I see is that parts may be hard to find and some of them may not be available.
Yes, as I said in 2009, the X5 was essentially the GT5, the GT7 was its bigger brother, more percussions, pistons for presets instead of tabs. Same overall sound.
Ace Tone is the name (or at least one of the names) that you're looking for.

HI ANDY
I mind reading about these organs a while ago,seamingly hammond bought into 0r took over the company
one of the head men in that company left and set up roland. about the one sold on e bay uk.it said at the bottom of the advert
it has a gold honeycomb contact strip under the keys which is pressure sensitive ie light pressure, low tone . heavy pressure, higher tone,
must have been early version of 9contact drawbar switch.
