Summer School Electronics Middle School Chorus Pedal

The Summer School Electronics Middle School Chorus is a lush, analogue bucket-brigade chorus pedal with a clever twist. Alongside its warm, liquid modulation, a second footswitch instantly flips the circuit into dedicated vibrato mode, complete with its own LFO and rate control. That means two fully independent modulation voices in a single, compact box, sharing a single depth control to keep your sounds cohesive and your pedalboard streamlined.

Designed and built by working musicians in Syracuse, NY, the Middle School Chorus is voiced to deliver everything from subtle widening to full-on watery warble. The analogue BBD core keeps things musical and organic, while the dual-footswitch layout lets you move between chorus and vibrato mid-song without touching a knob. Running on a standard 9-volt negative-centre power supply, it is ready to drop straight onto a modern pedalboard.

Warm Analogue Bucket-Brigade Chorus

At the heart of the Middle School Chorus is a true analogue bucket-brigade delay line, giving you the classic shimmer and movement players associate with vintage chorus units. The modulation feels smooth and three-dimensional, adding width and depth to clean tones and a gentle swirl to overdriven sounds. Because it is analogue, the effect sits naturally in a mix, enhancing your core tone rather than masking it.

Instant Vibrato Mode with Dedicated LFO

The second footswitch transforms the pedal into a dedicated vibrato, removing the dry signal and letting the pitch modulation take centre stage. This mode uses its own LFO and rate control, so you can dial in anything from slow, seasick wobble to fast, psychedelic warble without affecting your chorus settings. With a single tap you can jump from spacious chorus to expressive vibrato, perfect for dynamic live performances.

Two Independent Modulation Voices in One Pedal

Because chorus and vibrato each have their own rate control and LFO, the Middle School Chorus effectively functions as two separate pedals that share a single depth control. You can set a slow, subtle chorus and a faster, more intense vibrato, then move between them on the fly. This dual-voice design saves valuable pedalboard space and power outputs, while still giving you the flexibility of a multi-pedal setup.

Built by Working Musicians

The Middle School Chorus is made in Syracuse, NY by musicians who understand what players need from a gig-ready pedal. The layout is straightforward and practical, with clearly defined footswitches for each mode and controls that respond musically across their range. Powered by a standard 9-volt negative-centre supply, it integrates easily into existing boards and is built to deliver reliable, inspiring modulation night after night.

• Analogue Bucket-Brigade Chorus Circuit - The analogue BBD design delivers warm, classic chorus tones with a smooth, musical character. It enhances your sound with natural width and movement, ideal for everything from subtle thickening to pronounced, liquid modulation.
• Dedicated Vibrato Mode with Separate LFO - A second footswitch engages a true vibrato mode that uses its own LFO and rate control. This lets you craft a completely different modulation feel for vibrato, then access it instantly without disturbing your chorus settings.
• Two Effects in One to Save Space and Power - With independent chorus and vibrato rates and a shared depth control, the Middle School Chorus behaves like two pedals in a single enclosure. This reduces the number of pedals and power connections you need, freeing up space for the rest of your rig.
• Pedalboard-Friendly Power and Construction - Designed by working musicians in Syracuse, NY, the pedal runs on a standard 9-volt negative-centre power supply. Its straightforward layout and robust build make it easy to integrate into modern pedalboards for both studio and stage use.
