70’s Carlsbro Suzz Pedal

The Suzz Pedal was part of Carlsbro’s aluminium range. Released in the 70’s, they were guitar effects pedals encased in large aluminium outer shells and built like tanks.

They were extremely large pedals and have, over the years, become extremely collectible. Not only due to their unusual look, but their vintage sound and build quality.

This particular pedal has an Electro Harmonics Big Muff type distortion / overdrive sound. It’s not really a fuzz pedal, as the name would suggest.

It’s an incredibly simple pedal. Just two knobs, gain (volume / level) and sustain (amount of distortion).

It has no mains power and will only take a 9v battery which means removing two screws from a panel at the bottom every time you need to replace it.

It’s a great looking and sounding pedal.

Here’s what it sounds like on both guitar and bass. Please let me know what you think:

70’s Carlsbro Analog Echo Pedal

Where do I start with this crazy pedal? First off, it’s ginormous. Like, unnecessarily vast. I don’t imagine it would leave much space on my tiny pedal board. BUT, once I got over the initial shock of opening the box to find a pedal twice the size of my foot, I plugged it in and actually warmed to it pretty quickly.

Here it is next to a boss tuner pedal:

I was initially surprised to find that it doesn’t do longer delays at all. I opened it up to see if I could calibrate it and make the delays longer but it’s very hard to get into. And to cut a long story short, I couldn’t be bothered! It may well be possible, but I’m not going to attempt it. What this pedal does do very well is shorter surf rock slap back echoes.

It is capable of everything from nice, warm, analog dub reggae tones to harsh, extreme noise rock abrasiveness.

I could see it being used in noise and ambient music to create vast soundscapes. Combined with reverb it creates a huge sound and when you turn the swell knob up (see vid) to the point where it’s almost out of control, it’s actually really exciting to use. I like the element of chaos you get from cranking everything up and letting this pedal go haywire.

It’s possible to run this echo pedal in stereo and mono modes. It has two output sockets. One for the effected signal and one for the clean. So you can run them out to two amps and blend the sound.

I bought this with the intention of reviewing it and selling it straight on but I’ve fallen in love with it. I don’t know if I can part with it! I seem to have found it in a rare finish, too. Most I’ve seen have been in a silver aluminium casing but mine is black and looks much cooler, in my opinion.
