Fisher Dynamic Space Expander K-10

1960s valve spring reverb unit. Overhauled and fully functional.

NOTE: photo is of a previous unit we sold. Photos of the current one will be uploaded shortly, or can be sent to the purchaser before shipping.

Made in the USA, originally with RCA/Sylvania valves and a Gibbs reverb tank, this is the sound of King Tubby and Lee Perry. A valve spring reverb is not something you’ll find (effectively) replicated in plug-in form: it’s a living, breathing sound. 

This Fisher Dynamic Space Expander is for sale serviced and in good working order (bear in mind this is based on vintage 60s technology so isn’t whisper quiet). Fitted with a three-core mains cable for electrical safety and should be securely-mounted when installed. See detailed photos to assess condition.

USA 110v model. Will require a step-down transformer for use in the UK/EU. We do not recommend using cheap generic Chinese mains transformers and can supply a high quality UK-made transformer if required.

Here’s a demo from a while back featuring one of these in our old studio:

For sales in UK/EU the price will include VAT. VAT-free sales are possible to businesses and individuals in the EU (outside the UK) with a valid VAT Number – please get in touch if you wish to buy this way.
