How to Get a Chicago-Style Sound Through a PA for blues harp

Black Dog amp tone - Tell me how you got that sound on Black Dog.

Page: We put my Les Paul through a direct box, and from there into a mic channel. We used the mic amp of the mixing board to get distortion. Then we ran it through two Urie 1176 Universal compressors in series. Then each line was triple-tracked. Curiously, I was listening to that track when we were reviewing the tapes and the guitars almost sound like an analog synthesizer.

Ridge Farm Gas Cooker - excerpts:

The Ridge Farm Industries "Gas Cooker" is a high performance all-valve, twin channel Direct Injection (DI) box, designed to meet the exacting standards of the studio, broadcast and live recording industries. It excels in direct injection of high impedance instruments such as electric guitars and basses and can be used to add controllable degrees of classic-sounding valve warmth and presence to any mono or stereo audio source. The Gas Cooker includes a switchable 20dB input pad, a buffered, unbalanced line output (pre-gain control), and both balanced and unbalanced post gain control outputs. The balanced output features transformer isolation and switchable ground lift, while the unbalanced output has a maximum gain of x30, so guitars and basses can be matched to the line input of a mixing console. Carefully designed, high voltage valve circuitry permits the drive level to the output tube stage to be varied, so the amount of valve colouration added to the signal can be precisely controlled.

Guitars & basses -- Use it on instruments with active or passive pickup systems. You can also connect it between guitar and effects pedals. High gain settings give exceptionally warm valve colouration. Use both Cooker channels to provide a balanced split to two amps.

Electronic keyboards -- Treat in the same way as electric guitar signals. High gain settings will introduce significant colouration. If the source signal is relatively strong, you can produce a classic 'rock organ' sound [better would be saturating power tubes directly driving speakers hard]. More subtle setting of the Gain control will affect mainly high frequency sounds, enhancing both transient detail and presence.

Consoles -- The Gas Cooker will subtly enhance any signal when connected to the console's insert points. The best results are usually achieved by setting the Cooker to unity gain. If this produces too high a level of colouration, switching in the pad and taking the signal from the unbalanced output will compensate for lost gain.

Mixing -- To enhance the complete mix, connect both channels of the unit via the console's master stereo insert points. For a more pronounced effect, use higher gain. High levels of colouration work best on individual instrumental sounds.

Microphones -- To re-create that classic 'valve mic' sound, connect one channel of the Gas Cooker to the insert point of a mic channel using, the unbalanced jack output. For subtle colouration,set the Pad switch to on and adjust the gain control to provide approximately unity gain. Higher degrees of colouration can be achieved on higher gain settings or by switching off the Pad.
