I am thinking about building a Boss OD-1 clone.
The original had the RA3403 quad op-amp chip - are there any close equivs - couldn't find a data sheet for the 3403 - did find someone using a TLC2274 somewhere.
Any help would be appreciated.
Thanks
Bill
I found this:

if you ignore the prefix, it is a quad opamp (4 x 741? we can do better than this), optimised for single battery supply. looks a bit like an lm324. the tlc series also does single supply.
Smallbear carries a JRC3403, which ought to do you nicely.
