![]() ![]() On the rear panel you´ll find jack sockets to hook up external speakers with an impedance switch. Tremolo has been retained, with speed and depth controls, and finally there´s a master volume and the traditional backwards ‘cut´ control, which takes out highs as you turn the knob clockwise. As it was with the AC30HW, reverb is an integral part of the Custom Classic, featuring tone and level controls combined with a useful Dwell switch that varies the reverb circuit´s input level. Then there are volume, treble and bass controls for the Top Boost channel and another switch that allows you to swap between standard and ‘custom´ EQ types. The normal channel has a single volume control with a toggle switch marked ‘brilliance´ that adds extra highs. Next to these is a small toggle switch that allows you to ‘jumper´ both channels together, replacing the patch lead many players use on standard AC30s, to thicken up the sound and widen the amps tonal range. There are two input jacks - one for the normal channel and one for the Top Boost channel. ![]() The Custom Classic´s controls are an interesting mix of old and new with a number of cool ‘boutique´ features. ![]() Just like an original AC30, to replace any valve means taking the chassis out and you may also need a soldering iron to disconnect the speaker leads. Preamp valve bases are soldered into the main vertical PCB, while the power valves are hand-wired. The electronics (including all the controls) are PCB mounted on a mixture of double and single-sided boards connected by neat wiring. The chassis follows the original AC30 L-shape layout, with preamp valves mounted horizontally and power valves (including a GZ34 rectifier) mounted vertically. ![]()
