Analogue Distortion/Compression based on the Battery Acid IDOW edition module by Hexinverter

DIY distortion with custom panel.

BatteryACID is a unique voltage controlled analogue distortion module for musical synthesis. It is loosely based on the infamous MXR Distortion Plus guitar pedal which acid house musicians have taken to processing distorted acid basslines and other synthesizer textures through.

Where batteryACID differs greatly from its guitar pedal counterparts is that it has been designed to have voltage control of the distortion amount. This makes it right at home in a modular analogue synthesizer, as fun modulation of the distortion parameter is of course possible! It sounds great on synth leads, basslines and of course drums!

For anyone that might be familiar with the older DIY ("do it yourself") batteryACID project offered by hexinverter.net in PCB form, to answer your likely question: This is an entirely different and updated circuit. It features a slew of new features and differences, as outlined below.Technical/Mechanical Specifications

==Base Features==
- Voltage controlled all-analogue distortion effect
- Onboard compressor for automatic gain correction (the signal volume would otherwise vary drastically with the distortion modulation)
- Designed anew specifically for musical synthesis and drum processing
- Can function as a basic standalone hardware compressor when the distortion effect is switched off

==Analogue Distortion with Voltage Control==
- A new take on the classic diode overdrive distortion circuit found in many infamous guitar pedals of the last half-century
- Fully analogue voltage control of the distortion amount parameter
- The high-pass effect (ie: bass frequency loss) commonly experienced with using guitar pedals to process synths and drums has been reduced
- Effect wet/dry mix control for dialing in the perfect amount of distortion
- Attenuators for input/output levels
- Bypassing is possible via the panel switch

==Onboard Compressor==
- Can be disabled easily via the switch on the panel
- Compressor Threshold, Ratio and Gain parameter controls for locking in the desired dynamics after distortion
- Functions as a basic analogue hardware compressor when distortion is disabled
