Here is a GRP Synthesizer A4 in very good condition which was purchased at the Vemia auction in 2022. Everything works fine. In the process of testing, I realised how much I will miss this synth. However, I do not currently have a dedicated studio so space is a problem for me.
I'm guessing that anyone looking to buy this synth will already know most of the details. The construction quality is truly fantastic, like an Italian sports car. The knobs are a joy to turn. The sound is extremely high quality. I would say a 60's/70's style sound, where it can do Radiophonic Workshop or more conventional tones. Jean-Michel Jarre is very fond of this model and has been using one with his live sets for the past few years. It has a large number of filter choices and routings. It sounds great alone, or connect a pedal or two and you can travel to other galaxies very easily.
I had wanted this synth for years, and it was too tempting to resist, but I live in a smaller house now and I really have to let the A4 go. Please note the fairly small scratch on the wooden casing. There are a couple of other smaller marks too. I genuinely cannot remember if they were there when I bought it. I've kept it covered when not in use.
See lot 30927 for a companion sequencer from the same seller.
