{"product_id":"coppersound-cir-kit-breadboard-bundle-3-band-eq-422673","title":"Cir-Kit Breadboard Bundle 3-Band EQ","description":"\u003ch3\u003eA \"Baxandall\" EQ: the classic that teaches you to listen (and understand)\u003c\/h3\u003e\u003cp\u003eThe 3-Band EQ from the Cir-Kit range is based on the spirit of Baxandall equalizers, known for their natural behavior and effectiveness when you want to \u003cstrong\u003ebalance a sound without making it artificial\u003c\/strong\u003e. In practice, it's one of the best playgrounds for progressing in DIY: you immediately hear the impact of an adjustment and quickly understand the role of the components shaping the frequency response. This kit places you at the heart of this \"studio\" logic: adjust, compare, refine... and retain what really works on your rig.\u003c\/p\u003e\u003ch3\u003eWho is this kit for, and in which styles does it make the most sense?\u003c\/h3\u003e\u003cp\u003eThis bundle is aimed at curious guitarists, educators, makers, and pedal enthusiasts who want to \u003cstrong\u003emove from usage to understanding\u003c\/strong\u003e. New to electronics? The breadboard format (no soldering for assembly on the board) is ideal for stress-free learning: you build, listen, and correct. Already comfortable? You gain a quick tool to prototype an EQ section, compare several values, or prepare a \"final\" version intended for a future pedalboard.\u003c\/p\u003e\u003cp\u003eMusically, a 3-band EQ is a Swiss army knife: blues and classic rock to thicken the low end and tame overly sharp highs, funk to clean up the bass and bring out the attack, metal to adjust presence and control the low spectrum, ambient and post-rock to precisely place the guitar in the mix. In the studio, it's an excellent tracking companion: you correct the guitar at the source. Live, it's a formidable solution to adapt your sound to a venue (while keeping your identity).\u003c\/p\u003e\u003ch3\u003eA DIY experience designed for fast prototyping and clean progress\u003c\/h3\u003e\u003cp\u003eThe Cir-Kit principle is simple: you have a breadboard dedicated to the audio signal and an intuitive guide that walks you through the assembly \u003cstrong\u003estep by step\u003c\/strong\u003e. The goal is not only to get a functional effect but also to help you understand \"why\" each connection exists. You progress at your own pace, following a progressive method that greatly reduces common mistakes (polarities, power rails, placement accuracy, etc.).\u003c\/p\u003e\u003cp\u003eAnd because DIY is also about good habits: get into the habit of \u003cstrong\u003etesting your components\u003c\/strong\u003e and checking your assembly throughout the steps. A breadboard encourages experimentation, but that's also what makes it demanding: a misoriented component, a shifted connection, or reversed power supply can be enough to make you lose time. Here, the guided approach is precisely there to help you learn to diagnose, correct, and progress independently.\u003c\/p\u003e\u003ch3\u003eSound\u003c\/h3\u003e\u003cp\u003eA well-designed 3-band EQ doesn't just \"boost\" or \"cut\": it gives you the feeling of \u003cstrong\u003erepositioning\u003c\/strong\u003e your guitar in the mix. Expect effective equalization to tighten the bass (without muddiness), shape the mids (to move forward or back in the band), and adjust the highs (to regain brightness or, conversely, tame a harsh amp). On an already saturated chain (overdrive, distortion, fuzz), the EQ becomes a precision tool: you can tighten the low end, avoid the \"muddy\" effect, or highlight a frequency that makes your leads sing.\u003c\/p\u003e\u003cp\u003eAs with any breadboard assembly, the result will depend on your wiring, power supply, and tests: that's exactly the point. This kit is made so you can hear the differences, understand what you're modifying, and build your own vision of the \"perfect EQ\" for your guitar, pickups, and amp.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr)
