Fantastic old dual drum trigger, very synthetic sounding, bright and grainy. Capable of producing some crazy noises. This one is the clown of the kits, always fooling around and making people laugh.

One of the many 'accompaniment' preset rhythm boxes. Full of bosa nova and teen beat groves, this machine rises above most thanks to the number and quality of different blips and splats it can produce. To top it off, some of the sounds are easily adjusted, producing longer 808 style kicks that are quite weighty.

One of the custom Kinloch Electro Acoustics made Moog filter devices, these sounds were made by plugging in an old Simmons pad into the filter, setting the resonance up high, and sampling the outcome. A good variety of sounds, from bassy kicks to sharp tones.

This is a five input drum trigger unit. White noise everything, the sounds are nonetheless useful.

One of the most basic drum machines ever made, the DR-55 still managed to have a unique character, with very short and clicky sounds. Some people prefer the kick on this to the 606 for electronic beats.

Single drum trigger box, this was designed to clamp onto the rim of a tom or snare and be triggered by the vibration when the drum was hit. Simple percussive synthesiser produces clangy metallic sounds, boomy kicks and the dreaded disco tom sound.

Another 'accompaniment' style rhythm boxes, a little more aggressive than the Selmer but with a more limited range of sounds. To get some variation, the kicks are recorded clean, with a little distortion and finally with a lot. This machine lent its name to the big beat outfit Bentley Rhythm Ace.

A true, inbuilt rhythm machine in a cheep Italian home keyboard. Horrible amount of noise, with the weedy sounds just about poking above the sea of hiss. Lovely.
