Two of the Best Boost Circuits Are Now Available in One Pedal, Here's What That's Like | Ultimate Guitar

ultimate-guitar.com

Summer School Electronics' Extra Credit Boost pedal hits the right notes by combining two classic boost circuits into one compact design, offering both sparkle and warmth. It shines in enhancing guitar tone without merely cranking up the volume, which is perfect for musicians looking to add depth without overpowering the mix. The op amp boost reminiscent of the DOD 250 and the Bootster's chimey profile offer distinct tonal options. While it may not dazzle at first glance, its practicality and tonal versatility make it a serious contender for a permanent spot on any pedalboard, standing out in a crowded market.
