Equipped with Proper Passive™ Electronics.
All of my Proper Equipped guitars sell quickly. I’ll have more if you miss out.
This brand new 2026 Firefly Madcat comes equipped with our proprietary Proper Passive™ tone system while remaining 100% factory original otherwise. See the video below.
Proper Passive™ is designed around one simple idea: give players everything they need and nothing they don’t. No batteries. No active circuitry. No gimmicks. Just an incredibly musical passive control layout that transforms the way your guitar responds.
Cranston Guitars Tech Summary:
• Brand new 2026 Firefly Madcat.
• Equipped with our proprietary Proper Passive™ tone system featuring premium paper-in-oil and silver mica capacitors.
• Crank your favorite tube amp into its sweet spot and simply roll the guitar’s volume back to 1 for home use while retaining exceptional clarity, dynamics, and touch sensitivity. No attenuator required.
• Tone control is fully usable from 0–10. At 0, it delivers a warm, chewy, vocal John Mayer-style cocked wah EQ with incredible clarity. At 10, it delivers maximum presence, sparkle, and attack. Every setting in between is musical.
• Position 2 has been specifically tuned to remain full, punchy, and dynamic. Unlike traditional Tele-style wiring that can sound thin in the middle position, Proper Passive™ keeps Position 2 every bit as inspiring as Positions 1 and 3.
• Original factory pickups, hardware, finish, and cosmetics remain untouched.
• Complete professional setup performed before shipping including neck relief, action, intonation, electronics inspection, and multiple days of play testing.

We don’t just love Strats—we adore them. Proper Instruments redefines the simplicity of Leo’s original design. Most Strats are muddy when the tone controls are below 7. Players just live with it—or add a treble bleed.
That’s child’s play.
Proper Passive is built to be usable from 0–10—you can’t get a bad sound, even at bedroom volumes. 0 starts your journey—JM/BB-style. 10 delivers full SRV bite and presence. Everything in between is there for the taking.
All with no batteries or useless blender controls, Ever.
Setup, overhaul, or full restoration—we’ve got you.
Every guitar is different. We take the time to understand what you have and what you want before recommending our services. No upsells. No guesswork. Just real guidance backed by experience.
For larger or specialty work, we partner with Boylan Guitars in Harrisville, RI—our community partner.
