1966 Vox Pathfinder with Boss SE70 effects into 300 watt Class D amp

Running a Lace Pickup equipped Fender Strat through an old 8 watt 1966 Vox Pathfinder guitar amp with a tap off of the speaker into a Boss Direct Box and from the direct box into a Boss SE70 Effects box and finally the SE70's line level stereo outputs into a 150 watt per side Class D power amplifier that drives a pair of 8 inch coaxial full range auto speakers.
The concept is to ultimately design a similar compact and lightweight tube amplifier with effects that has an adjustable volume output for club work.
