CARLSBRO REVERB UNIT

Carlsbro 4 Channel Reverb for sale in very good cosmetic condition and perfect working order

For a unit made in the late sixties or early-mid seventies, this mains-powered spring reverb unit is in great shape. A perfect match for guitars and vintage valve amps, but also a very useful and unique sonic texture for studio use. It’s no slouch in the looks department, either – very cool…

If you want more information on which spring is best for you then check out our detailed spring reverb blog and “Springathon” demo (13 springs head-to-head). You can also see our full current stock of vintage studio signal processors here, but if you have any questions please get in touch as we have many years experience with these machines. 

Everything works as it should with this unit, though care needs to be taken setting the correct input level to get good results. The pots are smooth and crackle-free. (Please note: it is always possible that crackly pots/sliders may develop over time when equipment has not been used – even during shipping – this can usually be easily rectified either by use or judicious application of suitable switch-cleaning spray).

There are scuffs and scrapes to the tolex on the case but the face is in surprisingly good condition. See the detailed photos.

As it is a UK 240v model, it will require a step-up transformer for use in countries with 100-120v mains supplies. The UK plug will be removed before shipping overseas to any countries with 230-240v mains electricity unless otherwise requested.

We can supply high quality, UK-made transformers if required. We do not recommend using cheap generic Chinese mains transformers and can supply a high quality UK-made transformer if required.

Spring reverbs are a great ‘secret weapon’ to have in the studio arsenal – not just for the ‘boingy’ effect as used by dub and reggae pioneers such as Lee ‘Scratch’ Perry, but also for adding that unmistakable classic shimmery vibe to electric guitars. It’s a sound that lends itself well to modern production: the perfect treatment for overly-sterile  digital delays and reverbs and it can be heard all over today’s music. Whether it’s cutting-edge dubstep from Rusko, top pop mix engineers like Tom Elmhirst (who used vintage spring reverb all over the last Adele album), or the Alabama Shakes’ album, ‘Boys And Girls’, the sound of springs is everywhere right now.

Try using a little tape delay before sending to a spring reverb, or use a digital/plug-in reverb and send the wet output from that to the spring to add character.
