Been experimenting with a few inexpensive Dyna Comp/Ross clones after building the BYOC version. Have decided I like the BYOC I built the best so on the block these go. Both are in as new/mint condition and were only tried once for comparison at home. Both prices include shipping to the lower 48 USA and as always trades are welcome. $40.00 OBO. Joyo JF-10 Dynamic Compressor. Cool compressor with CA3080E chip and added attack control knob. Very versatile and low noise. $50.00 OBO. Biyang CO-10. Has he coveted CA3080E chip mounted in a socket ready for experimentation. This one sounds closest to the BYOC and is one of the quietest compressors I have ever tried.
