• EDP Wasp Repair

    I suspect this Wasp was bought of ebay here (at Matrixsynth) as it had the same crack and the cloth tape on the back. The drone is caused by a faulty AR (with broken CMOS IC’s) not capacitance.

  • Roland Space Echo RE-201 Repair

    This space echo didn’t have anything major wrong with it, just there were a lot of small problems that made it a bit poor for performing. It is a really excellent tape delay .. partly because it has a nice muffley effect on your sound and partly because there is something quite special about the way the delay moves when you change the tape speed. It is one of those machines that feel nice to play with even though you could probably do the same with a much more compact plug-in or simulator ( Boss RE-20 .) It is quite common for people to think that it doesn’t work properly when they plug in a guitar, this is because the impedance of both the ‘mic’ and ‘instrument’ inputs are quite low so when you plug the relatively high output impedance of a guitar into it you loose a lot of the high end. To solve this you can use a guitar pedal before the input or get it modified.

  • Octave Cat SRM Repair

    This keyboard has a strange duophonic mode that is fun but slightly useless, it assigns one VCO to the lower pressed key and the other VCO to the upper pressed key but doesn’t touch anything else. So rather than 2 ‘Voices’ it is 2 pitches. Its quite well known that Arp sued them claiming it was a copy of their Oddesey design 1. Great thing about the design is that there is almost every type of modulation you could wish for and it has both an ADSR and AR both assignable anywhere at the flick of a switch. Making the VCO’s modulate each other is particularly interesting, there are therefore quite a lot of FM sound opportunities.
