Description

Edit description

There are two parts to Robert Keeley's mod of the Boss DD-3 digital delay pedal. First, he adds switchable analog feel to this industry-standard compact delay by incorporating two different smoothing capacitors. Use the small three-way switch to select between these caps or the original stock sound of the DD-3.

The second mod takes the DD-3's direct out and turns it into an effects loop, allowing you to add any external effect just to the DD-3's repeats. Add slight chorus or phase to the signal to simulate tape effects, or experiment to find whatever your imagination wants!

Modded for analog feel and incredible tonal possibilities!

The high-cut mod might not work on the version C of the DD-3 due to a change in how the control works since 2010.

It's essential to examine the main PCB for a small DIP8 IC and a larger DIP IC to verify compatibility with the mod.

The high-cut mod is likely compatible with the DD-3T, but testing before drilling is advised to avoid unnecessary damage.

Keeley Modded Boss DD-3 Digital Delay –

effectsbay.com

The Keeley Modded Boss DD-3 Digital Delay pedal is a creative powerhouse for delay enthusiasts. With a switchable analog feel and an effects loop, it offers versatility not commonly found in compact pedals. The added capacitor gives the repeats a dark, analog texture, while the effects loop allows for customized, effected repeats. Users can toggle between a warm analog simulation or the original digital sound, making this pedal a flexible choice for those seeking variety in their soundscapes. However, the $209 price tag might be a deterrent for some budget-conscious musicians. Overall, this pedal is a compelling choice for those wanting to experiment and expand their delay options.

"Anyway, I now prefer a Keeley-modded Boss DD-3 pedal. The Keeley modifications provide some 'warmer' delay effects choices while I am still able to get my old DD-3 weirdness happening (as in, really fast, heavy repeat-laden, digital-sounding, electro spazz-outs that I can cut on and off with no trail off). And, of course, I can get simple, tasteful bounce. I can get by with a plain old DD-3, too, but the Keeley one is just a bit better."
