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

Premium quality classic blues/rock pedal that works very well with complex overdriven amp sound. This pedal is now offered as lower-priced pcb-model or hand-wired pedal. Both share the same specs and tone.
It’s a low compression, high headroom overdrive with high output, and it has a Body knob for adjusting low-mid content and treble. The LGW was made to be a stackable overdrive that could go anywhere in the pedal chain and the compression normally associated with this type of circuit is reduced same as several distortion mechanisms.

Manual

Little Green Wonder

Like that legendary tone, this pedal produces intense drive while retaining high definition. The pedal also includes a built-in reverb circuit to add ambiance and depth to your sound.

“1”’s gain ranges from medium to very heavy distortion. The amount can be easily controlled via the volume control on your guitar. (Input impedance is set to facilitate this, and is somewhat negated if a buffer or buffered effect is used ahead of “1”.) The Brown knob controls the amount and harmonic overtones of the distortion. Getting the exact tonal quality is the key to this legendary sound and “1”’s Brown and Presence controls help it appropriately interface with a wide variety of pickups and amplifiers.

"The Blueberry Overdrive from Mad Professor offers a wide range of tones within quite a narrow part of the overall drive category. We’re talking about overdrive here, not clean boost, distortion or fuzz. Overdrive, baby!

Versatility is high and low at the same time in this case – low in the sense that it basically does one thing, and one thing alone. That said, the tonal possibilities within that limited range of ‘just’ overdrive, are quite amazing. And while you may argue that it is nothing but transparent and also adds compression that you can’t really control other than with playing dynamics, I find the drive both musical and pleasant when you find just the right setting which is relatively easy."

Blueberry Bass Overdrive

Royal Blue Overdrive offers a wide range of tones from light overdrive into distortion and at lowest Distortion knob setting works as an EQ. It can also be used to create tube amp-like crunchy ‘strike hard for distortion’ effect. There is not much filtering on the overdrive, to provide a transparent tone that you can tailor with both the Treble and Bass controls.
