The Fruity Toot Compressor pedal sports a super fine 25-turn trimmer on the bias control. This expands the "sweet spot" to an easier to adjust option. 
A treble control has been added that is basically a treble boost. At zero it is the stock circuit with no treble added. As you turn it up it adds treble but DOES NOT cut bass at all. This adds a nice SPARKLE to your tine, and only vintage capacitors and resistors are used in the circuit. 
 
From Freakshow: "About 14 years ago I had a Dan Armstrong orange 'crusher' compressor pedal and loved it! I eventually traced the circuit and designed a circuit board for it. Well......I basically forgot about it for all these years and recently I said... "HEY that was a great pedal!!!!" so I decided it was time to make my own version of that classic compressor. SO here we are... the 'Fruity Toot' is born!"
