I know that you mentioned in an earlier thread that you didn't like the Aggie pre but you may also want to expand the search to include an Aguilar OPB-3. It may have just been the wood combo that you heard it in because it really is very similar to the Bart 3-band with a bit more open sounding highs (still great mid's). Most Roscoeheads that like the Bart pre like the Aggie too.
Just a thought...........
Here's a link to an Aggie OBP-3 for sale:
