Verified · 89/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Magnatone Custom 450 is an Estey-era deluxe combo built around Magnatone's patented varistor pitch vibrato. Two channels, each with high- and low-gain inputs on a 12AX7 and their own Volume, Tone and Normal/Bright switch, feed 6CG7 varistor stages with a 12DW7 oscillator (Speed, Depth, footswitch). A 6DR7 drives spring reverb with a footswitch, and a pair of 6973s on an EZ81/6CA4 rectifier drives a 12-inch and a 5-inch speaker.
