Rich, fat, warm sound and well thought out functionality make 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 dealing 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.

We Welcome Part Exchange

We welcome part exchanges on items over £500. We realise that sometimes you need to “move something on” to get your new guitar. We give fair prices and once agreed we stick to them. The only thing we ask is that you accurately describe your guitar. We have plenty of happy customers from our part exchange scheme.

How it works – If you are local, you can simply call in. If you are not local we will assess your guitar and give you a valuation via phone/e-mail (we may ask for pictures). Once the price is agreed, we always stick to it, and your new guitar will be removed from the market so the deal can be concluded.

You can either send us your guitar, or we can use our courier to pick up for a small charge (UK only). Once the guitar is with us and any balance is paid we can dispatch your new guitar.
