OUT OF THE BLUE
AION Bill of Materials (BOM) religiously followed here. Most parts were purchased from Mouser Electronics. Other parts came from Small Bear Electronics & Tayda. I also used parts that I already had in stock. Strictly – NO VALUE substitution in this project.
BBDs, Clock Generators & Companders: CoolAudio brands
I opted for the “Stock Bypass” wirng method.
OpAmps: OPA2134 & TL072
I noted that there’s a typo in the Calibration Instruction. Correction should be: TR1 adjusts IC3 & TR2 adjusts IC9.
I followed the CoolAudio bias voltage – 3.36VDC & courtesy of a helpful Aion customer. The chorus effect is excellent! All the toggle switch combinations work with discernible effect changes. Very cool chorus effects! I tested the Blueshift extensively on the Clean channel my Fender 2×12 combo amp.
I will do further testing with the MN3207/MN3102 BBD/clock combination to see if there will be big differences in the chorus effect. I’m also looking forward to calibrating Blueshift further with the LabNation SmartScope. Overall, the Blueshift Chorus is indeed a challenging project to build but very rewarding once you get it working!
FYI, I use a P-touch 2730, Mac & Win compatible tape printer for the labels, 3M vinyl car wraps for enclosure color & aesthetics.
Thanks to Kevin for resurrecting the classic Boss DC-2 Dimension C Chorus. It’s a labor of love!
How many Boss pedals projects have you cloned? Try the Blueshift Chorus & tell us about it. Thanks.
