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!

EQ

While Ed Sheeran primarily relies on the natural sound of his acoustic guitar and vocals, he occasionally uses EQ (Equalization) to shape and enhance his tone during live performances or in the studio. EQ pedals or onboard preamps can allow him to adjust the frequency response of his guitar signal to suit the acoustics of different venues or to achieve specific tonal characteristics. Here’s how EQ might be utilized in Ed Sheeran’s setup:

1. **Tonal Shaping**: EQ can be used to adjust the balance of frequencies in the guitar signal, allowing Ed Sheeran to shape his tone to his liking. For example, he might boost the midrange frequencies to bring out the warmth and presence of his acoustic guitar, or cut certain frequencies to reduce any harshness or mud in the sound.

2. **Feedback Control**: In a live setting, EQ can help control feedback by notching out problematic frequencies that might cause the guitar signal to feed back through the amplification system. This can be particularly useful when performing in venues with challenging acoustics or high volume levels.

3. **Room Correction**: In situations where the venue’s acoustics are less than ideal, EQ can be used to compensate for any deficiencies in the sound. By adjusting the EQ settings, Ed Sheeran can tailor the guitar tone to sound more balanced and natural, regardless of the room’s acoustic properties.

4. **Matching Gear**: EQ can also be used to match the tone of Ed Sheeran’s guitar to the sound of other instruments or equipment in his setup. For example, he might adjust the EQ to complement the tonal characteristics of his vocal microphone or to blend seamlessly with backing tracks or other instruments.

Overall, while EQ may not be a central component of Ed Sheeran’s guitar effects setup, it can still play a valuable role in shaping his tone and ensuring that he achieves the desired sound in different performance environments. Whether used subtly for tonal shaping or more aggressively for feedback control, EQ allows Ed Sheeran to tailor his guitar tone to suit his musical vision and performance needs.

Preamp

A preamp pedal shapes and boosts your guitar’s signal before it reaches your amp or recording interface, giving you control over tone, gain, and headroom. It acts as the first stage of amplification, adding warmth, clarity, and character while preparing your signal for the next part of the chain. Some preamps emulate the response of classic valve circuits, while others offer clean, transparent tone shaping ideal for acoustic instruments or direct recording setups.

Used on its own, a preamp pedal can serve as the foundation of your tone, providing a consistent core sound wherever you play. When combined with other effects, it enhances dynamics and helps each pedal sound more defined and natural. Whether you’re looking to push your amp harder, bring life to a dull signal, or refine your sound for the studio, a good preamp pedal adds presence, punch, and musicality to any rig.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
