USER MANUAL

Mercury1 is the single-channel evolution of the already famous Mercury EL34.

Mercury1 inherits many of the features that made its big brother famous all around

the world. Its DNA is therefore very similar, but with some new and brilliant reinter-

pretations that make it truly unique in its kind.

Quality control

This manual contains a lot of informations useful to have in-depth knowledge of the equipment. Therefore we recommend that you read this manual carefully in order to use its potentials to the very best. All of our products are made on an artisan basis and therefore you may nd some small acoustic and/or aestetich dierences. This is the very best guarantee of a truly hand-made product.

The Customwork series is equipped with specic components to achieve exactly

the sound result we were looking for. Every resistance, capacitor, transformer or

component on the signal path has a very specic role. Precisely for this reason

many of the main components are built according to our specications. Mercury1

oers features that are dierent from other amps for some absolutely original

circuit choices. You have purchased one of the more "modern" products on the

market if we can dene a tube amplier as “modern”. You will be amazed, like many

of our other customers who have a Customwork series amplier.

So... enjoy your Mercury1!

single channel series

edgy brown

gain : Controls the amount of gain of the pre-amp stages. You can obtain sounds ranging from

clean to crunch even pushed, up to the extreme super-lead Plexi style with the hi switch inserted

brown : Changes the distortion structure. With the switch to OFF, the sound is more balanced

and dened; with the switch to ON, harmonics and sound are richer at the ends of the spectrum

edgy : Increases high frequencies denition volume : Power amp volume control. It works after the eects loop treble - middle - bass : Equalization controls. They act softly and eectively presence : Increases the medium to high frequencies. Useful to emphasize the solo parts stdby : ON / OFF switch to play power : Main ON/OFF switch
