"TAD redefines Spring Reverberation. When the manufacturing of Accutronics Reverb cans in the USA has been announced to close down in 2008 TAD started the research for an own high quality production of the classic spring reverberation units. The goal was to create a drop-in replacement bringing back that stunning reverb sound that Fender made so popular since the early 1960s.

The TAD Reverb Cans achieve this goal and even more: deep and smooth reverb, no fluttering but wide frequency response with airy top end instantly inspiring to enjoy guitar playing. The rock solid mechanical design assures a very dependable and consistent quality performance exceeding any expectation. A drop-in replacement and upgrade as well for vintage as for modern reverb cans by size, performance and tone."

Pure Tone’s new long threaded three pole (stereo) 1/4" jack provides full contact for improved connections and signal integrity. This jack locks the cable securely into place creating a greater surface area connection to carry more signal for an improved frequency stability. This jack is a great choice for both mono and stereo applications as well as guitars using active electronics.

Pure Tone has developed a high quality 1/4" three pole (stereo) jack using a new patented design that improves upon and offers a more reliable connection than standard 1/4" jacks. The Pure Tone design features two springs for both the tip connection, a spring for the ring, and an additional spring for the shield connection. These help to secure the plug into place and create a greater surface area connection at contact points to improve stability and signal integrity. These jacks also increase the current capability of 1/4" connections.
