Summer School Electronics Extra Credit Boost Pedal

The Summer School Electronics Extra Credit Boost is a compact, dual-voice boost pedal that gives you instant control over your level, clarity and grit. Flick the toggle left for a clean, one-knob op-amp boost that simply makes everything bigger, or switch right to engage a transistor-based boost with an adjustable Brightness control for added sparkle and bite. Whether you want a transparent level lift, a cutting solo tone or an always-on preamp feel, Extra Credit delivers it with ease.

Hand built by working musicians, the Extra Credit is designed to slot effortlessly into any rig. It works brilliantly at the end of your chain to push your amp for solos, in front of your favourite overdrive to add saturation and presence, or as a subtle tone enhancer that stays on all night. Powered by a standard 9-volt centre-negative supply and backed by a lifetime warranty, it is a reliable, road-ready tool that rewards every stomp with musical, usable boost.

Two Boost Circuits in One Pedal

At the heart of the Extra Credit is a simple toggle that completely changes the character of the pedal. To the left you get a straightforward op-amp boost, ideal when you just need more of your existing sound without extra colour. Flip it right and you are in transistor territory, with a more textured, harmonically rich boost that can add grit and presence. Having both options under one footswitch means you can cover subtle level lifts and more aggressive tonal shaping from a single compact box.

Op-Amp Mode for Clean, Transparent Lift

With the toggle set to op-amp mode, the Extra Credit behaves as a one-knob clean boost. This is perfect for pushing your amp just a little harder, lifting your volume for leads or tightening up your entire signal without changing the core voice of your guitar and pedals. It is an excellent choice if you love your base tone and simply want it louder, clearer and more authoritative in the mix.

Transistor Mode with Brightness Control

Switching to the transistor-based side engages the Brightness control, letting you dial in extra top-end sparkle and edge. Turn it up for more cut and definition so your solos slice through a busy band mix, or back it off for a warmer, slightly gritty push that wakes up darker amps and pickups. This mode excels when you want your boost to add character as well as level, giving you a more expressive, touch-sensitive response under the fingers.

Flexible Placement for Multiple Roles

The Extra Credit is voiced to work in several key spots on your board. At the end of your chain it acts as a powerful solo boost, lifting your entire sound without upsetting your carefully crafted pedal settings. Placed before an overdrive, it can add gain and saturation for thicker rhythm parts or more sustain. Used as an always-on preamp, it can subtly enhance clarity, presence and feel, making your whole rig sound more alive and responsive.

Hand Built with Lifetime Backing

Each Extra Credit is hand built in Syracuse, NY by working musicians who understand what a dependable boost pedal needs to do night after night. Attention to detail in construction and component choice helps ensure consistent performance, while the standard 9-volt centre-negative power input keeps it compatible with most pedalboard supplies. A lifetime warranty offers additional peace of mind, making the Extra Credit a long-term addition to your setup.

• Dual-Voice Boost Design - The onboard toggle lets you choose between op-amp and transistor-based boost circuits, giving you both a clean, transparent lift and a more characterful, gritty option in a single pedal. This flexibility means you can cover multiple roles on your board without adding extra boxes.
• Brightness Control for Extra Sparkle - In transistor mode, the dedicated Brightness control allows you to fine-tune the top end of your boosted tone. Add shimmer and cut to stand out in the mix, or roll it back for a smoother, warmer push that still enhances clarity.
• Versatile Placement in Your Signal Chain - The Extra Credit works equally well at the end of your chain for solo boosts, in front of overdrives for added grit, or as an always-on preamp. This makes it a highly adaptable tool that can enhance almost any rig or playing style.
• Hand Built with Lifetime Warranty - Constructed by hand in Syracuse, NY with careful attention to detail, the Extra Credit is built for real-world use by gigging musicians. The inclusion of a lifetime warranty provides long-term confidence in its reliability and performance.
