Bogner Harlow Boost & Bloom Pedal

Written by

Elliot Stent

This latest range of pedals from amp genius Reinhold Bogner has been co designed with transformers coming from none other than Rupert Neve. Known for redfining the rock sound with rich overtones and excellent harmonics Rupert Neve's amazing transformers have made their way in to this pedal for the best classic rock sound possible.

The Harlow is a cool boost pedal that can go between a soft clean boost to a much more powerful gain filled overdrive that gives that broken up clean effect. What makes this pedal really special however is the built in Bloom compressor control. Set down low you get next to no compression but turn it up and you introduce more smoothing out your tone.

Simple Controls

With just three controls this pedal is incredibly easy to get up and running. Just set the level first to either match your amplifier or boost it however much you want, then set the tone to fit your amplifier and guitar. This is a wide sweeping EQ that covers everything from incredibly dark and warm to sharp and harsh so it is well worth experimenting with. At the higher end of the level control things start to get a little bit fuzzy for when you really need that extra gain boost.

The compression at 0 is pretty much off and by the time you are at 4 or 5 you will be getting sweet singing sustain. Turning it up further you start to really squash the sound in a more funky kind of way. This reduces the attack and smoothes out your whole sound for a consistant response.

A Pedal Like No Other

Bogner and Rupert Never have spent and incredible amount of time fine tuning not only the transformer but the pedals themselves. The goal was to capture that classic rock studio tone that became part of the Rupert Neve sound. If you wanted this sound previously the only way was a massive mixing desk worth thousands, now it is at your feet in this pedal.

Here's what Bogner say about the Harlow Boost & Bloom Pedal

The Bogner Harlow is a unique boost pedal with a "Bloom" compression feature, which serves up dynamic three-dimensional punch and tastefully transparent squeeze. The 100% analog circuit delivers a wide range of boost - from crystal-clear light boost to a thick and meaty high-output assault on your amp's input section - you'll never want to turn it off. At the heart of the Harlow is a custom audio transformer created by legendary audio pioneer Mr. Rupert Neve.
