Mesa Boogie Stowaway Compact Class-A Input Buffer Pedal

Reclaim Your Tone: The Ultimate Pedalboard Insurance Policy

The Guitar Sanctuary is proud to present the Mesa Boogie Stowaway Input Buffer—the ultimate compact tone-saver hand-built in Petaluma, California. If you are running a pedalboard with multiple true-bypass stomps, or utilizing cable runs longer than 15 feet, your guitar's signal is suffering from high-frequency roll-off caused by cumulative cable capacitance. The Stowaway acts as a vital security gate right at the front of your signal chain, converting your guitar's sensitive high-impedance signal into a robust, low-impedance output that passes through complex routing networks completely untouched.

100% Discrete Class-A Performance in a Mini Footprint

Unlike cheap utility utility switchers or standard IC operational amplifiers that introduce harshness or digital coloration, the Stowaway features a 100% discrete, all-transistor Class-A circuit design. This premium architecture provides a completely transparent, dynamic interface that mimics the direct, organic feel of plugging your guitar straight into a world-class boutique tube amplifier. It delivers an optimal input load for your pickups, restoring the sparkling top-end chime, immediate touch-sensitive transient response, and foundational low-end punch that gets lost to pedalboard signal drag.

Stow It Anywhere: Clever Compact Utility

Engineered strictly for utility and convenience, the Stowaway's ultra-compact micro chassis is specifically designed to fit almost anywhere. It easily mounts beneath heavy-duty pedalboards, tucks away into a tight corner on top of your board, or mounts inside an amplifier rack system. Equipped with robust RFI filtering to reject unwanted radio frequency interference and unwanted noise, it ensures your rig stays dead-quiet whether you are tracking pristine clean tracks in the studio or running through unpredictable venue power grids on stage.
