Title: help me debug boss ce-2 chorus please!...
Post by: tasos on February 27, 2011, 02:42:05 PM
hey!this chorus is digital right?[hope it is in the right category]
http://www.madbeanpedals.com/projects/PorkBarrel/docs/PorkBarrel_ver.2.pdf (http://www.madbeanpedals.com/projects/PorkBarrel/docs/PorkBarrel_ver.2.pdf)  this is the application file...
here is my problem...i get nice chorus as i should but the output is really low!nothing like a misbiased circuit!all my voltages are ok...
could you please tell me what is wrong or which part of the circuit should i examine some more?[i have already spent many hours on it but nothing!
thanks! tasos.... :)

It's not digital. Digital would be basically 1's and 0's - programmed devices utilizing binary. BBD's are analog devices even though they are quantized in time, they store analog voltages sequentially (infinite possible voltage states at each sample).

Did you adjust the trimpot correctly?

Is it LOW low, or just kinda quiet?
