the "Get down make love" effects-wank is made with a harmonizer and delay pedal. The first album is indeed The Game / Fkash which used analogue synthesizers - a Hammond organ is no way a synthesiser, just like an electric piano isn't a synthesiser, because they generate a sound on a different way than a synth, like f.e. the Jupiter. The "no synth"-statement is just to prove the listeners and the guys from the production company (as Brian said once) that everything they hear is guitar, bass, piano and drums, so nobody could say "oh that Synth sounds nice".
That`s very true, and to add something:
Synths tend to be very under-rated in some ways, and overly so in others. Specially back in the 70s. Some people actually thought that the high "for me" in Bo Rhap was a synth, and there`s an interview to Roger in which they ask him if that`s really his voice or a synth. Now, very few people can make a synth generate a wolf howl. How could it be possible to make a synth pronunciate words and more to the point sing?
That`s why the band put the "no synths" statement. As far as I know, there`s no synth able to do the effects of Get Down Make Love either. Queen (and prog bands in general, if I dare call Queen a prog band, at least during their first 5 albums) used a lot more studio/contemporary effects, than synths. With very few exceptions (e.g. Genesis), synths were used in pop music only for the following purposes, which aren`t related at all with analog substractive synthesis:
- Bass lines (e.g. Staying Power, Body Language...)
- Pads (e.g. Invisible Man, techno music, New Era, etc)
- Robotic sounds (e.g. Machines, A Human Body, Radio Ga Ga, Styx`s Mr Robotto...)
- Arpeggiator (e.g. Duran Duran`s Rio, Queen`s Action This Day & Las Palabras De Amor)
- Instrument Impressions
By the last point I mean, for example, to do violin parts in the keyboard. That was very useful and is nowadays very popular, because, for example, in Led Zeppelin`s All My Love, they would have to hire a 40 piece string orchestra and a trumpet player just for that song; and it would cost a lot of money (besides paying the conductor, the orchestra, the instruments, the transportation, think of how many mics and amps they`d have to add to the stage, and all just for a song). So it was easier to have those sounds stored in a keyboard that Jonesy played.
Nowadays hardly more than 1% of semi-pro bands or orchestra (either salsa, pop, rock or whatever) use synths. Now they use "workstations" (i.e. keyboards in which you can`t create sounds in, but you can use the pre-sets which fullfil the already mentioned functions).
Yes and Genesis are part of the very few group of rock bands that actually used synths or samplers for effects. The rest used some of the following:
- Backwards
- Tape Phasing
- Looping
- Reverb
- Fade
Then there`s the combination of those. For example in Ogre Battle the outro has some reverb. When it was reversed (for the intro), the echo came first and then the actual part, so it was a "phantom" like effect which didn`t require synths at all.
There are also specific effects for each instrument. In piano the best known one is the Phil Spector effect (which he didn`t invent but popularized), consisting in one person getting inside the piano and plucking the strings, while other person played. That way the piano "rang" (check Nevermore at the end of the verse).
In guitar, specially electric, there are many well-known "weird" effects, most of them achieved through pedals (listen to Rage Against The Machine). A good one which I just love is the effect of using a Talkbox and start tapping, while you generate very low sounds with your mouth.
