Williams OC44 Ranger - Germanium Treble Booster

Based on the original Range Master Treble Booster, this little box was the secret ingredient of many of the 1960's guitarists from the UK. It's sound is heard at its absolute best on early Eric Clapton recordings, most notably the Bluesbreaker album with John Mayall. Set your tube amp to the edge of breaking-up, just at that sweet spot, and dial in the The Ranger. The Ranger kicks the amp into tube heaven, highlighting the upper mids, giving all those Rory Gallagher, Eric Clapton tones we love. Dirty, raw and fiery but with that shimmer and sweet tone that also cleans up amazingly well with the guitar volume control.

The Ranger is fitted with a switch that lets you choose between the normal, sweet sounding, upper mid boosted Range Master tone to a similar tone but with a bit more body and add lower mid tones mixed back in. This is a super useful switch that as well as offering a whole bigger range of tones from the pedal, also allows you to quickly and easily match the pedal with different amps and / or guitars. A really great addition to what I think is one of the best sounding pedals currently available.

The Williams Ranger features an original nos Mullard OC44 / OC44K or Mullard OC71, not an equivalent transistor as usually found on most other modern Range Master pedals. Vintage Capacitors carefully selected to match the tone.

This is a short demo of the old style Ranger before the new tone switching option was added. This video nicely demonstrates the difference between the pure amp tone and the Ranger being used. Coming soon will be a new video including the tone switch. - Williams Audio Ranger Treble Booster (Dallas Rangemaster w/ NOS Mullard OC44'
