    Product Description

    Hamstead are renowned for their guitar amps, but their growing pedal range has garnered plenty of plaudits in recent years. The latest stompbox to join their stellar lineup is the Zenith - a flexible tone-shaping pedal that combines EQ, boost and compression effects. The unit is designed to ultimately get the most out of any amplifier; refining its sound to perfection or pushing it to a whole new level!

    From subtle compression through to extreme sound-sculpting and sustain, Zenith’s three distinct circuits cover it all. Digitally-controlled switching allows the fully-analogue EQ and compression circuits to be accessed independently too - all via one reliable 'OptoKick' footswitch made by The GigRig.

    Musical EQ & Compression

    Treble, Middle and Bass controls are customary on many guitar effects, but Hamstead endeavoured to voice these parameters to not only sound great, but feel natural to use too. Boosted high frequencies are present but not harsh, boosted lows remain tight while adding warmth, and the Middle control offers a huge amount of range with its three position ‘Q’ and Frequency switches.

    Compression is often misunderstood, which is why Hamstead designed an easy-to-use circuit that delivers incredible fidelity yet provides enough versatility for fastidious players. This circuit has a very fast attack and medium/long release but remains very transparent, while the feel of the compressor can also be dialled-in with the Blend control - allowing for a natural picking attack while dramatically increasing sustain.

    Secret Switching

    The Zenith is Hamstead's first pedal to feature "Secret Switching" for independent control of its EQ and Compression circuits. By holding down the OptoKick footswitch, the pedal enters the programming mode with 5 switching options; Standard (both on, both off), Flip/Flop, Comp always on, EQ always on, and Cycle. For example: Zenith can be used as an always on EQ with compression engaged via the switch, or used to Flip/Flop between the two effects.

    Circuit Order Function

    One of the coolest additions to Zenith is the 'Circuit Order' switch on the rear of the pedal. This enables you to place the EQ either before, after, or in parallel to the Compression circuit. While a common studio practice, this is the first time this feature has been included in a compact guitar pedal.

    Effective in the Effects Loop!

    With its balance of EQ and Compression, Hamstead's Zenith is the perfect effects loop attenuator. When you have found your tonal nirvana at gig volume, turning an amp down to practice levels often results in EQ changes and lack of output tube sag and saturation.

    By running Zenith in the effects loop, you can first bring down the volume with the Level control without affecting preamp gain. Adjusting the EQ then brings back your original tone, and by adding a touch of compression - the feel of tube sag returns with musical bloom. With Zenith, you can recreate the sound and feel of your amp at its best - at all volume levels!

    Mr Alan Parkinson17th Jan 2022

    Very pleased with this. The compressor and boost functions have been very well thought out and there are a plethora of options without being overwhelming. The effects themselves are very musical and enhance everything in a pleasing way.

    Versatile tone shaper - does exactly what I hoped: high wuality clean compression, versatile EQ and boost, with easy control and option to switch the order of EQ and comp. Very well made and looks classy too. High end price, so I marked it down a little on value, that said it’s high-end quality so this may be a little unfair!

    Zenith compressor/boost/EQ just makes everything sound so much better. Really flexible and works brilliantly with all my amps and different humbucker/single coil guitars.
