Demeter Windings was established in 1990 by Keith Ward who has over 60 years of experience within the transformer industry. Keith started working in the industry at Drake Transformers where he helped manufacture and deliver some of the first transformers for Jim Marshall of the slightly well known Marshall Amplification.

​​We supply customers in the Guitar and Bass amplifier markets. Working with our customers we have designed and produced many transformers to the required specification. Many of these transformers and the products which they are in have been through and passed UL approvals.

Having supplied some of the biggest names in Guitar Amplification manufacturing we are also able to provide replacement transformers for these. Even if we haven't produced the transformer you require we will still try to help you get your Amp up and running again as soon as possible. So please use our contact page to get in touch with us.
