Project overview:

Based on Walrus Audio Deep Six Compressor with roots on the DynaComp and Ross Compressor. This four knobs beast works great for guitar or bass thanks to the internal trimmer that regulates how much of the signal is feed into the IC. Designed to operate with the IC LM13700 instead of the obsolete CA3080 that most of the compressors use. It’s recommended to operate this circuit at 18v, but remember that all the capacitors should be rated for more than 25V.
