Tremolo; And the day London fell silent

Tremolo; And the day London fell silent

Tremolo (Italian pronunciation: [ˈtrɛːmolo]), or tremolando ([tremoˈlando]) in music, is a trembling effect.

‘Amplitude variation’ rapidly turns the volume of a signal up and down, to create a “shuddering” effect.

Some electric guitars use a (somewhat misnamed) device called a “tremolo arm” or “whammy bar”. The pitch of a note or chord is lowered or raised, which is known as vibrato.

This non-standard use of the term “tremolo” refers to pitch, rather than amplitude.

Tremolo on BASS

The Nova Modulator NM-1 pedal by TC Electronic has a Tremolo effect, which sounds good on Bass, but as the Tri-chorus was the only other effect I liked, the NM-1 was moved on.

The mini size ‘Trelicopter’ by Mooer audio had some good reviews from other Bassists and sounded fine on youtube. I decided to order one.

My isolated power supply provided the milliamps and I switched in the ‘Trelicopter’ pedal in both my amps effects loop and direct between my Bass and amp. But, there were major issues.

The biggest one was the ‘depth’ control operating like a volume cut/boost control.

The ‘speed’ dial had a very limited range with little ‘effect’ on the sound. The ‘Bias’ knob was almost inaudible.

I’ve owned more effects pedals than I’ve changed strings on my Basses, but I can’t remember ever having to return a single one.

The supplier gave me a full refund. In the grand scheme, a minor disappointment.

July 7: London 7.7.05

2005. At this time, I was working just above Baker Street tube station. A commute of around 45-minutes (on a good day) via the Piccadilly and Jubilee Lines’.

Today was one of those days. The signals had failed somewhere, and the Piccadilly Line came to a halt.

It was around 08:00. The train stopped at Stamford Brook, and with the District Line moving on the adjacent line, I changed so I could get to Hammersmith.

I thought it might be quicker to get to work on the Circle Line instead. I arrived at Baker Street at around 08:45 and walked up the platform.

Train 216 was arriving and I looked to see if it was being operated by someone I recognised from one of the Depots. It wasn’t.

The next time I saw the train (number 216), a bomb had been detonated on board, which killed six passengers.

Four extremists has separately detonated three bombs in quick succession on board London Underground trains at Edgware Road, Aldgate and Russell Square, and later, a fourth on board the No.30 bus in Tavistock Square.

It is understood that this bomb was originally destined for Bank station on the Northern Line.

52 passengers were murdered and more than 700 injured in the four incidents, which was the United Kingdom’s first ever suicide attack.

26 people died at Russell Square on the Piccadilly line. 6 died at Edgware Road on the Circle Line. 7 died at Aldgate on the Circle Line and 13 died on the bus at Tavistock Square.

Olympic bid euphoria and then Silence

The euphoria of London winning the bid to host the 2012 Olympic Games the previous day, was short-lived.

All of the emergency services and London Underground staff displayed extraordinary bravery in descending into dark, smoke-filled Tube tunnels, aware they could face further bombs.

“I headed home as soon as I could. The trains were eerily silent on the return journey.

In the weeks that followed, there was understandable nervousness everywhere”.

A terrible feeling knowing we could be potential targets as commuters. Two weeks later on 22/7, another four would-be suicide bombers launched failed attacks on the Tube and a bus.

An innocent Brazilian, Jean Charles de Menezes was killed at Stockwell Underground station, when Police suspected him to be a terrorist.

“I wouldn’t go below ground on the tube for at least a year afterwards. It was difficult not to be suspicious of anyone naive enough to carry a rucksack on their back”.

The last word

2015 and the 10th anniversary of 7/7. A day etched into the memory and lives of so many people, who will remember; those who were lost, and those who survived, but at great cost.

“I will remember the day that London fell silent”.
