Hi Butch, You bet I remember the GLB. A good friend who lived 2 blocks away from me had a Standard SR146 with a GLB synth connected to one of the crystal positions. Another friend had a GLB attached to his TR22. The whole thing was kludged together with tie raps. It was bulky and unwieldy but got the job done. Dave Marthouse N2AAM [log in to unmask]
