Fender has stuck with this type of layout from the beginning and while it’s more than adequate, we’d be happier with through-plating on both boards and stranded hook-up wire replacing those ribbon connectors. The layout for all three amps is more or less the same: a large vertical single-sided PCB holding most of the small components including the panel knobs and switches, linked by ribbon cables to a more robust through-plated board sat horizontally in the bottom of the chassis, which holds the valve bases.

There’s also a new ‘lightly aged’ variation on the familiar sparkle grille cloth, which blends nicely with the black textured vinyl covering.īoth of the big combos feature a new loudspeaker, the very popular Celestion ‘A-Type’, with a single 12-inch driver in the HR Deluxe.īehind the rear panels of all three new amps, the electronics sit in robust open-ended steel tray chassis, which are secured to the cabinet top and sides with substantial mushroom-head machine screws. The black control panel has a slightly different textured finish, with more visible graphics and ivory chicken head knobs, which don’t quite match the lettering - a very tiny annoyance that could easily be tweaked with a different shade of paint.

Today, we’re looking closely at the Deluxe.īoth larger Hot Rod IV combos feature the same familiar cabinet design as their predecessors, which was in turn based on the legendary narrow panel ‘tweed’ amplifiers of the mid-to-late 50s. Fast forward to today and it’s time for another update: three models from the new Mk IV range: the HR Blues Deluxe IV, the HR Blues DeVille IV, and a limited edition of the Pro Junior IV.
