Got an email from Becos today. My compressor is on the way, but apparently they have upgraded the pedal with a new feature which mine will have. It is not yet on their website, so they sent me a link to the manual.
The new feature is a Side Chain Filter switch. Here's what the manual says about it and a picture of what the new pedal will look like:
View attachment 3855873
SCF SWITCH ‐ Side Chain Filter switch has two positions: Normal (N), Deep (D). In Normal position, the Side Chain Filter is set to accommodate a large range of audio signals and instruments. By design, it has an attenuation of lower frequencies below 1 KHz,which allows the compressor to act with a short delay and let lower frequencies pass through without triggering the compression right away. This setting renders a natural response that is suitable for most cases. In Deep (D) position, more of the lower end frequency (an additional ‐12dB@130Hz) is freed up to prevent triggering compressor kicking in too early. This setting lets more of the low end pass through at the output, while also lowering the amount of compression. This is a proper setting for guitar if a fuller sound is needed and especially for bass instrument.
Wow. They really pack this little box with features. I think I want/need one of those in the near future...
