Hamstead Soundworks first put the tremolo circuitry from its Artist +RT series amps into a pedal in 2016 with the Signature Analogue Tremolo, and now the company is back with a MKII version. 

This time it loses the extra footswitch for the boost circuit but offers a smaller footprint, a control input, a third waveform for the tremolo and a Shape control delivering the ability to tilt any of the waveforms to the left or right. 

As an all-analogue design, the pedal eschews the common use of digital waveform circuitry for an analogue circuit, resulting in three subtly different but great-sounding waveforms. 

The Classic setting delivers the authentic sound of output bias tremolo as found in some vintage amps, while Hamstead’s signature sinewave tremolo is buttery smooth, melding naturally with your tone.

• Walrus Audio Monument V2
Pretty much a do-everything trem, this features an extra tap tempo footswitch, five tremolo waveform shapes, and the choice of standard trem or the Harmonic type with a whisper of pitch shift.

• Supro 1310 Tremolo
A straightforward design with standard or harmonic tremolo. Extra tonal mojo comes via a Gain knob, which sets the level of preamp gain, adding various degrees of overdriven texture to the tremolo.

• Effectrode Delta-Trem
This is the UK-based valve pedal specialist’s take on tremolo. The vacuum valve design combined with with Raysistor photocell circuitry offers vintage tremolo sounds in mono or stereo with tap tempo.

The new kid on the block is the Triangle waveform, which you might expect to be more defined, but it’s not too far removed in flavour from the sinewave. Still, the Triangle waveform is capable of sawtooth and reverse sawtooth patterns with the Shape knob in play.

That knob has no effect in its notched central position, but turned left or right it skews the tremolo waveform in that direction. To the extreme left, the swift rise to the peak gives you a sharp attack for a choppy rhythmic sound.

Piling on the Shape knob with the Sinewave and Classic modes can deliver similar sounds, but it’s great in moderation for a little lopsided wave action to recreate some of the tremolos of certain vintage amps.

From a slow deep throb to a fast shimmer, the Depth and Speed knobs give you a great range, and the speed can be placed under the control of an expression pedal for changes on the fly.

The pedal displays none of the typical perceived volume drop when the effect is kicked in, so you can use the Gain knob (with up to 10dB of transparent boost) to emphasise the effect or use it to naturally push the front-end of your amp.


Waveform-shaping versatility adds another level to this excellent source of old-school ’board-based analogue tremolo.
