Analogue Waveform Perfection Tremolo is one of the earliest effects to be applied to the electric guitar, and its timeless quality has ensured its popularity across many genres throughout the years. Signature Analogue Tremolo is our take on this classic effect, created with the refined analogue engineering that Hamstead Soundworks is known for. The MkII Signature Tremolo takes our Signature ‘Sinewave’ circuit straight out of the Artist +RT series amplifiers and packages it into a pedalboard-friendly format. This is coupled with two additional tremolo modes, and the features of Wave Shaping, and expression & speed control pedal support.
