Instead of digital modeling or layered menus, they focused on real circuits, immediate control, and a signal path that behaves like a proper pedalboard.\nQuattro is built around four independent analog sections: Compressor, Overdrive, Chorus, and Echo. Each effect has its own dedicated controls and footswitch, allowing the design team to engage or bypass sections instantly during a performance — no scrolling, no presets, just play.\nThe signal starts with the Compressor\/Limiter circuit, offering controlled dynamics and level balancing without squashing the tone. From there, the two-channel Overdrive provides both crunch and high-gain stages, selectable on the fly. The voicing stays tight and articulate, with a tone control that works as a low-pass filter to keep the drive focused.\nNext in line is the Vintage Chorus, delivering classic modulation with simple Speed and Depth controls. Subtle settings add movement and width, while deeper settings bring out a more pronounced, vintage character.\nThe chain ends with the Echo section, voiced for warm, musical repeats. With controls for Level, Tone, Repeat, and Tap Tempo, we can move from slap-back delays to longer rhythmic echoes that stay clear and controlled.\nCarl also built in an effects loop between the overdrive and chorus sections. This allows us to insert a favorite drive or fuzz pedal exactly where it belongs in the signal chain — without rewiring the entire rig.\nQuattro runs on an internal regulated ±12V power supply, providing the headroom needed to use high-quality components and maintain low noise throughout the system. The result is a multi-effect that feels open, dynamic, and transparent — designed to sound like your amp, not like a processor.\nKey Features\nFive classic effects in one unit\nCompressor, Over Drive x 2, chorus and tap tempo delay\/echo\nSend\/Receive loop – for extra effects\nBuilt-in power supply\nEasy layout for fast live use\nStudio-quality analog sound\nDimensions: 410 x 160 x 70 \/ 16.14″ x 6.30″ x 2.76″\nWeight: 2.0 kg \/ 4.41 lbs\nSpecifi\ncations\nInput: 1M Ohm\nOutput: 100 Ohm\nS\/N Ratio: 56 dB\nCompression range: from 1:1 to 1:00\nGain range compressor: +-20 dB\nGain Overdrive max: 89 dB\nTone Overdrive: Cut filter (low pass)\nEcho time max: 1000 m.sec\nSend impedance loop: 200 Ohm\nReturn impedance: 1M Ohm","brand":"Carl","offers":[{"title":"Default Title","offer_id":51895715954973,"sku":"57385PT","price":1189.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/2092\/9309\/files\/57385PT_20b582fa-826d-4300-af6d-d1703f0c1757.webp?v=1782123083","url":"https:\/\/scarlettmusic.com.au\/products\/carl-martin-quattro-multi-effects-guitar-pedal-with-compressor-overdrive-chorus-delay-and-send-receive-loop","provider":"Scarlett Music","version":"1.0","type":"link"}
