Lab Gear

For a long time I couldn't afford synthesisers, so I settled for old lab gear. I guess it's the Sheffield way. There's a certain joy in experimenting with these things, the thrill of coaxing sounds out of a box that spent its previous life hooked up to a Vulcan Bomber...   ...and of course they're eminently modular. And quite a lot of them work right up into the video range, which is nice...
