The ANNEX MKII 100 Watt Quad Voice Dual Channel Tube Head brings versatility and sonic possibilities to a new level. The Annex Line was developed by Jonathan Nuñez and Gary Phillips of Overtone Works using a new approach in design. The mil spec point-to-point construction, unique design, as well as the highest quality components are all key in achieving true extended range and tone sculpting possibilities not available until now. The ANNEX MKII offers simple, straightforward, and intuitive controls along with a wide range of sounds, perfect for plug-and-play simplicity or in-depth sonic tweaking.

The ANNEX MKII is a 2 channel design where both channels can provide their own unique flavors of pristine cleans, clean with breakup, overdrive, punchy distortion, and high gain along with independent boosts per channel. You can dial back the amp and achieve a wide range of laid back and vintage tones, push the amp into new and modern territories, or merge the two channels to create something new altogether. An ideal amp for any style/genre no matter how extreme or particular the targeted tone/sound might be.

The ANNEX provides a unique low end depth along with the most powerful and musical equalization available. The 6-position Voice switch shapes the signal’s low-end before hitting the preamp section, allowing you to thicken up or tighten up your sound depending on your guitar and pedal layout. Each EQ knob in both channels is a push-pull pot that allows you to get full-range (out) or a tightened-up sound (in) for each frequency, giving freedom for all players to achieve their desired sounds whether extended, tight, or hybrid. You’ll be able to dial in clarity whether on stage or in the studio, while never having to sacrifice your tone or disrupting your band’s balance.

The "Range" control adds a top end detailed air with a silk lush quality to both channels which is fed into the power section. This control along with the rest of the EQ stage was designed to close the gap between what you get out of your amp and a completed record sound.

The ultra-transparent effects loops can be set to Series or Parallel. Series sends the entire signal through the effects loop, while Parallel lets you blend your dry and wet signals using an independent Return knob. The effect loops can be configured in different ways: 1 loop for both channels or loop 1 and 2 separately for each channel for your favorite pedals and effects. Selectable Hi: +4 / Low: -12 nominal sends and high impedance return levels make it extremely easy to use pedals or studio rack pieces.
