Rich, fat, warm sound and well thought out functionality makes the Mad Professor Dual Blue Delay one of the most clever, intuitive, and easy to use delay pedals currently available.

The short delay has a maximum delay time of 315ms and a fatter tone well suited for slapback and old-school tape echo tones. Long delay reaches 810ms and has a modern delay voicing, great for lead and ambient tones.

Both delays have wide range Tone controls for dialing in the perfect setting. Switch between the two delay channels or combine both together for huge dual-delay sounds. Keeping the On/Off switch depressed for 1 second brings you an exciting rhythmic multi-head mode. A must-have for all instrumental rock and Pink Floyd fans.Tap Tempo function is also included for use on the Long delay channel.

Dual Blue Delay is a powerful and intuitive pedal for the progressive musician.

Dual blue delay

A compact digital reverb pedal with pure-analog dry signal path, true-bypass switching, and controls for Time, Tone, and Reverb (depth), the Silver Spring proved a sparkling little performer in a range of settings. It ably subbed for a tube Fender Reverb Unit in front of a tweed-like combo for some surfy instrumentals, and worked equally well replacing a Bogner Goldfinger’s builtin spring reverb in the amp’s parallel FX loop. It doesn’t go splash when you kick it, and you might detect just a hair of pulsing in the wash of the effect’s decay, but all in all it’s a stellar sounding unit

Manual

Silver Spring Reverb

Hand-made in Finland premium quality tremolo pedal. Mad Professor Mellow Yellow Tremolo (MYT) is a true sine wave tremolo effect designed for tremolo tones from the of 50′s type soft swing to deep modulation with great playability, regardless of tremolo depth or speed.
The strength of the incoming signal is modulated by a sinusoidal oscillator, just like in the early amps, and modulation bias is set to give symmetrical modulation. This gives a very musical tremolo effect that blend very well with both clean and distorted guitar tones

Mellow Yellow Tremolo

The Golden Cello pedal delivers a huge singing overdrive tone, with high-quality tape echo type delay. To get this kind of tone anywhere else would cost you thousands of dollars and hours of knob twisting.

Just plug your Golden cello into your clean amplifier, and you’ll experience, mountainous, juicy lead tone at any volume level that only takes up one space on your pedal board. Sonic perfection is now in your hands and at your feet.
