From the vendor
Based on the EQD Acapulco Gold with an optional pre-gain mod. The Dirty Aztec is a super distortion board based of the sound of a cranked vintage Model T amplifier. The original version came with just one dial…volume…and by god – this thing is loud!!! So, we added an optional “pre-gain” pot. This replace the volume pot on your guitar, allowing you to control the gain – again, this is an optional extra and if you want to build the board without it – just jumper it!
The tone is set with your guitar, so if you want a darker, moody, doom sound…roll down the tone knob on your guitar.
Pre-Gain Mod
Without the pre-gain pot, this board is….LOUD! The pre-gain acts the same as the volume control on your guitar, so if you don’t want to mess with the guitar volume pot whilst you’re playing – the pre-gain pot is for you! However, if you want a one knob board that will fit in a 1590A and blow your ears off….there’s a simple way to do it.
Use the leg of a diode or some wire, and jumper pins 2 + 3 of the pre-gain pot. This will bypass it. leave pin one empty. If you wanted you could also wire this to a trim pot and have an interal control, the order for the pins goes 1/2/3 starting at the square pad.
That’s it, pre-gain by-passed. When you’re getting used to this pedal, we suggest the pre-gain all the way and slowly start the output at 1 and build up…then play around – it really is a face meltingly loud board!
