I thought someone might also be interested in my compressor design. It originated from looking at the Orange squeezer, but has more features, namely, totally discrete signal chain, gain control via a H11F1M opto FET and uses a zetex ZXCT1041 current sensor as a ideal full wave precision rectifier. I also have a simple op amp implementation that works fine(for rectifier) but the ZXCT1041 is really great for converting signal level to control voltage- it works reliably up 50Khz or so. The circuit provides control for compression level and out level. Its quiet, has no critical adjustments and uses little power.

I am new to this forum and thought someone might find my amp design interesting. Its a guitar amp designed for busking and uses a cordless drill or SLA  battery for power. It has discrete circuitry until the final amp which is a TDA7360. Its relatively simple but has all kinds of potential for tweaks and I am sure others can come up with improvements.
I have attached the schematic. Sound samples, circuit variations and pictures can be seen at:
