The Twin Head pedal by Artec features amp simulation modeling which allows you to switch from American blues to British rock very simply without the need to buy expensive racks and the like. This is possibly the most cost effective amp modeling effect you will find.

There are two pre-shaping tone circuits in the design of this pedal, one being 'classic' and the other being 'crunch'.

Comes complete with instructions and a 9V battery.

Connections are standard guitar jack in and out and a jack for external 9V supply.

Bypass is true direct bypass to guarantee your tone.
