About us

Since 2008, DoxyWorld has been manufacturing 1W-style transistor recording amplifiers. Our goal is to replicate our model, a small amp based on the Supersonic PR80 radio audio amp section, in tone and in look.

Our range

Our products are designed to sound as close as possible to their model. Each product differs on the accuracy of its tone, of its look and the presence of some additional features.

How we work

Our products are manufactured by hand in France. When impossible to source, some electronics parts are also hand-made to exact specifications of their vintage counterpart.

Our customers

Most of our customers use our products with a Red Special guitar and a treble booster. While the treble booster is a 'must-use', our amps will give good results with different type of guitars.

Technical specifications

The Supersonic Doxy is a small recording amplifier. This amp-in-a-transparent-pedal is a modern replica, using off-the shelf components, of the Supersonic PR80 radio amplifier section. This is the circuit enclosed in Brian May's recording amplifier, that can be heard on most of the famous Queen hits.
The Supersonic Doxy needs to be plugged in a small bookshelf speaker cabinet, whether home-built or vintage.
DoxyWorld will not supply the speaker cabinet with the Supersonic Doxy. So there will be an element of experimentation with speakers and crossovers.

Build yourself a speaker cabinet, including a woofer and a tweeter, or buy one off any auction website. Then, you will have to include a crossover in your speaker cabinet. A Butterworth 1st order crossover will be the best technical choice for that matter.

Most modern woofers and tweeters are 8 ohms, but if you buy a vintage speaker cabinet, please check the speakers impedance, and use these values with the above simulator. Experiment with the a low-pass and high-pass frequency varying between 2000 and 3000 Hz. This will give you some choke and cap values to work with. From there, you can compare the results you get with the Supersonic Doxy against the tone heard in Queen/Brian May's original recordings, until you are happy.
Please note again DoxyWorld won't supply speakers or crossover elements with a a Supersonic Doxy. Shoud you feel uneasy with making your own speaker cabinet, please consider buying a Supersonic Pro instead.
