This is a compact and easy-to-build compressor circuit designed by Jon. It is known for its tonal transparency and low noise. The compressor knob allows for a wide range of compression, from almost none to a noticeable effect. The L/H toggle switch offers two decay options: a short decay for subtle peak limiting and a long decay for a mild “duck and swell” sustainer effect. This switch also affects the overall amount of compression available.

In addition to its compression capabilities, the Bear Hug can also function as a lead boost, providing a boost of approximately 10-15dB even on higher compression settings.

The controls on the Bear Hug include:

– VOL: Output level control.
– COMP: Compression amount control. Turning it fully counterclockwise results in little to no compression, allowing the circuit to be used as a boost.
– BIAS: This trimmer is used to set the bias voltage of Q1.

Overall, the Bear Hug compressor is a versatile and compact option that offers a range of compression options, from subtle to more pronounced, as well as the ability to function as a lead boost.
