Hand-wired, 40-watt all-tube combo amplifier built by the Fender Custom Shop. It replicates the legendary 1964 "Blackface" AA763 circuit made famous by blues icon Stevie Ray Vaughan, incorporating unique modifications designed by his personal amp technician, Cesar Diaz. 

Unlike standard production reissues, this model was built with premium, point-to-point construction and featured highly specialized tonal controls on the rear panel. 

Key Specifications & Architecture

• Power Output: 40 Watts via two 6L6 power tubes.
• Speaker Configuration: 1x15" combo, utilizing a large speaker format that delivers a distinctively bouncy, scooped-mid tone with massive low-end clarity.
• Tube Layout: Four 12AX7 and two 12AT7 preamp/effects tubes, with a GZ34 rectifier tube.
• Cabinet Construction: Finger-jointed solid pine cabinet for superior acoustic resonance. 

The Cesar Diaz ModificationsThe standout feature of the '64 Reissue is its rear-panel toggle switches, allowing players to instantly change the amp's internal physics to replicate Cesar Diaz's personal tweaks for SRV: 

• Stock vs. Modified Switch: Flipping this to "Modified" results in a massive gain boost, sending a raw, overdriven signal straight to the Vibrato channel. 
• Diode vs. Tube Rectifier Switch: Players can choose between the classic sag of the GZ34 tube rectifier or the tighter response, faster attack, and increased headroom of a solid-state silicon diode rectifier. 

INCLUDED: Webber Mass 100w Attenuator. Perfect new condition and sounds fantastic. Unlike purely resistive attenuators that can make an amp sound flat, the MASS series uses a moving coil speaker motor as a reactive load, preserving the natural feel, dynamics, and interaction between your amplifier's output section and the attenuator. High-quality cables provided as well. Reactive Load Technology: Employs a real speaker cone motor internally. This mimics the complex impedance curves of a real speaker cabinet, avoiding the "fizzy" or heavily compressed artifacts common in cheaper units.
