OR100H The 100 Watt Head For the Rock Guitarist

The Orange OR100 Head is an amazing rock amplifier that any metal guitarist will have on their shopping list! Now 3 years old it was top of the OR Series tree then... and it still is today! Better still, the new amp utilises the very best valve technology to create a tone that is “oh so very special” to a rock guitarist! Essentially it recaptures a vintage “Old School British” tone but keeps a careful eye to modern day functionality.

Pushing out 100 watts of characteristically Orange tone, this crown jewel of the OR series can also be reined in for smaller venues or a more “gentle” atmosphere. The output power can be scaled down to settings of 70, 50 and 30 watts. Even the low power setting has more kick than many guitarists expect!

The unusually rich tones come from an array of valves that the Orange design team spent a long time over. Eventually they developed the perfect combination for you metal players out there! The power amp is driven by 4 el34 valves with the pre amp pushing the pickup signal through 4 ecc83/12ax7. The unusual branched power supply runs the preamp stage at a slightly higher voltage to deliver cleaner headroom and a slightly beefier tone.

The FX loop is driven by a 12at7 of its own to produce sounds of thermionic mayhem! This unique Orange sound – the supposed ‘the holy grail’ of tones didn’t just happen by accident!
Its twin channel technology gives enormous flexibility to guitarists. The clean is a non-master type that gives a tight low end but with good headroom and some serious Orange “character”! The dirty channel has been engineered with 3 gain stages. Rich in high end harmonics, this can take the OR100 Head from rock to thrash at the twist of a knob! You’ll be playing in hard rock heaven with the huge dynamic range, ultra clear note separation and wealth of colourful gain textures

The OR100’s valve buffered effects loop and the switchable power output settings are supplemented by foot-switchable gain boost on the dirty channel. There’s also a foot-switchable global boost that delivers an additional 3dB to either channel for that song that just makes you want to rock the roof!

The “Pics Only” fascia pays further tribute to Orange’s ‘Graphic’ amplifiers from 1972 onwards, making the OR100H a powerful player’s blend of the best of the old and the new: in its rock tones, rugged construction and modernistic design.
