HH Electronic IC-100

It was quite common to see Pink Floyd with the HH Electronic IC-100 amps on stage in the early 70s. While the rest of the band used their IC-100s only as pre-amps, Roger Waters used it also together with a Binson Echorec delay unit to produce a tremolo effect. (See One of These Days track, 2:00 - 2:30).
"One day, Roger decided to take some of the techniques that I was developing and try them out himself on bass. And he came up with that basic riff that we all worked on and turned into One of these Days," says Gilmour to Guitar World magazine.
"For the middle section, another piece of technology came into play: an H&H amp with vibrato (sic). I set the vibrato to more or less the same tempo as the delay. But the delay was in 3/4 increments of the beat and the vibrato went with the beat. I just played the bass through it and made up that little section, which we then stuck on to a bit of tape and edited in. The tape splices were then camouflaged with cymbal crashes."
The IC-100 solid state amps were manufactured by the UK company HH Electronic (now owned by Laney). They offered the 100 watts RMS of undistorted output, two channels with a full range of tone controls and a volume control on each channel. Each channel had two inputs, normal and bright. In addition to a Volume, Treble and Bass knobs, the amp had a Presence control on channel 1 and a Brilliance on channel 2. On the first channel there was a Sustain that fattened-up the sound by adding an extra gain/harmonics in parallel to the existing signal. Effects (controlable with a footswitch) included a Reverb and Tremolo.
