The Quattro begins with Carl Martin's award winning Compressor/Limiter circuit with single controls for compression and level. The Two-Channel Overdrive has switches for on-off, and for selecting between the crunch and high-gain stages, and controls for tone and level. In classic fashion, the Vintage Chorus has a speed and a depth control. Finally, the vintage style Echo has controls for level, tone, repeat and tap-tempo, as well as an on-off switch. No hard to read screens, no menus to scroll through, just set-up and play. There is no simpler multi-effect available! There is also an effects loop built in between the overdrive and chorus effects for that special drive or fuzz pedal that is part of your sound.

You also get that famous Carl Martin build quality, ultra quiet switching, a high quality on-board regulated +/-12V power supply which allows us to use the finest components allowing the greatest amount of headroom, and low output impedance which leaves your amp sounding exactly like your amp.

It's about friggin time!


I own the best analog effects that money can buy. This box holds its own against them and is durable, inspiring, quiet and toneful. Add a tuner and you can gig and cover so much ground it's just fantastic. A super pedal that really has no competition in modern effects. The old Ibanez PUE5 is close but but I like this better. The two distortions give you just what you need to gig and it SOO small and sweet sounding. It is expensive but worth it. Value is measured in worth not price and this offers so much value. The chorus is nice and reasonable quiet, delay is comprable to the Carbon Copy, distortions are a little like a Mesa dirty channel - full bodied distortion that retains the character of the guitar. Compressor is better than Boss and not quite up to Keeley standards. Again - all effects are very usable. It's a professional piece of gear that pro's will feel right at home with. So simple - bless you CM and company!
