if it was a pedal, it may have been one the Roland guitar synths. The current version is the GR-55

You can get guitar synths all day long on eBay for pretty good prices (compared to new.. Roland is really proud of their products, if you know what I mean)


I recently bought a GR-55, and it is one of the best gear acquisitions I've ever made. Above and beyond the synth capability is the guitar and effects modelling. It is amazing what they can do to reproduce the sounds of just about any guitar, amp or effects pedal ever made.

For example, if you want the sound of a strat played through a vox amp with gain at 50% and volume on 3, select those attributes, and that's what it will sound like!

Or if you want the sound of a rickenbacker 12 string played through the clean channel of a fender twin, they modelled that too.
The acoustic guitar models are also good.. you can make your electric sound just like a steel string acoustic.. or a nylon string guitar.. you can even create custom instruments by swapping pickup models (single coil, humbucker, lipstick, p-90 whatever)

And you can even program special tunings without having to touch your machine heads at all. They're pricey, but all things considered... Best bang for the buck I've ever seen.

If you go to youtube and search for GR-55 you'll get enough hits to watch for days without seeing the same thing twice.
