Diamond Pedals updates Memory Lane delay with STM32 core

October 1, 2025 · 3 sources

Diamond Pedals unveiled an updated Memory Lane delay in October 2025, built around a new STM32 core¹. The pedal is the latest version of the company's delay line, which the original Memory Lane began in analog form before digital replacements arrived from 2011¹.

The new version uses Diamond's digital Bucket Brigade Device design, a digital replica of a BBD that the company's team created in the last decade¹. Guitar Pedal X describes it as a BBD-style circuit using three distinct delay lines paired with analog companding and anti-aliasing and reconstruction filters². The STM32 processor extends the delay range to up to 2400 ms, with lower noise, more headroom and improved signal-to-noise ratio and frequency response, according to that report². Gearnews gives the maximum as 2.4 seconds³.

Four modes are selected via the Tap/Mode switch: MLjr, a fixed-rate delay with silent tempo changes; Vintage, with warm, saturated repeats; Galloping 2-Head, a dual-head rhythmic pattern inspired by the Counterpoint delay; and Ambient 3-Head, with cascading repeats¹²³. Controls are Mix, Feedback, Delay, Modulation and Tap [Mode], with an on/off footswitch and a dedicated tap tempo footswitch²³. Tap subdivisions are quarter note, dotted eighth and half note, shown by green, yellow and red LEDs³. The tap footswitch also doubles the delay when held, in momentary or latching operation³. Other features include Auto Div, which doubles or halves tapped tempo outside a mode's range, Geezer mode for classic Memory Lane operation without secondary footswitch functions, Trails mode, and momentary or latching modulation¹². The pedal has top-mounted jacks, Burr-Brown equipped buffered bypass with optional trails, and soft touch relay switching, and is handmade in Montreal¹². It runs on a 9V DC supply at roughly 50 mA².

Pricing differs between the two reports that give a US figure: Guitar Pedal X lists $259², while Gearnews lists $294 and says the pedal is available now at Thomann³. Guitar Pedal X reported it available for orders, with international dealers to follow².
