Up for sale, a 2013 Cornell Custom Amplification Plexi 45/50 1x12” combo amplifier in exceptional condition and in perfect working order. Hand-built in the UK, this finely crafted boutique combo features a dual-channel, dual-input design, with a 45/50 rectifier switch for maximum versatility and breadth of Plexi tones.
Simple, user-friendly controls include independent Volume controls (Normal Volume: Channel 1, Treble Volume: Channel 2), Treble, Middle, and Bass EQ, and Presence knobs. At the heart of this Cornell is the 45/50 rectifier switch, which toggles from valve (45) to semiconductor (50): the valve rectifier yields a bluesy “sag,” extremely soulful and dynamic to user inputs, and the semiconductor rectifier has a quicker response and improved transient attack. Additionally, the High/Low switch reduces the output to 15 watts, ideal for controlling headroom at any volume level. The Cornell 45/50 is at its best dialed up, delivering super creamy breakup with fantastic harmonic texture and ripping crunch, while the cleans are muscular and silky smooth.
This Cornell features point-to-point wiring, with components mounted onto a proprietary board and then sealed in conformal coating for noise prevention and component life extension. The matched JJ tube complement comprises a pair of KT66 power tubes, with three ECC83s in the preamp section, and a GZ34 rectifier. The Scumback S75-PVC 12” Alnico speaker (dated 12-27-13) is designed as a cross between an early Kraft paper voice coil-era “Blue Alnico” (seen in original BluesBreaker combos) and a Silver Vox Alnico, rated at 65 watts, delivering woody upper midrange cut and sweet, bell-like trebles.
Cosmetic touches include black tolex, gold hardware accents and piping, and a salt-and-pepper grillcloth, and wear is limited to a couple small tolex tears and scuffs.
